Abstract:

It is important to understand the physiological acclimatization process in order to provide the favorable growing conditions, to increase the survival rate and to produce vigorous seedlings for field planting for better establishment. These aspects assume significance because the embryo culture technique is used for germplasm collection in coconut. The zygotic embryos from eight month old selfed nuts from West Coast Tall (WCT) cultivar of coconut were collected for embryo culture. The field planted seedlings produced by embryo culture and those raised from nursery were compared for photosynthetic activity under field grown conditions. Photosynthetic and water relation parameters were studied in the embryo cultured plantlets at different stages of acclimatization under green net house conditions. The photosynthetic rate increased gradually during acclimation with maximum rate atfour months after transfer to pots (under 50% shade; stage 4). The embryo cultured plantlets had higher photosynthetic rates compared to the nursery raised plants under field conditions. Transpiration rate increased with stage during acclimation. Embryo cultured plants had low transpiration rate as compared to the nursery raised plants. Consequently embrvo cultured plants had higher WUE (A/E). The WUE increased during acclimation. The Fv/Fm ratio increased gradually from 0.69 to 0.72 till stage 4. The field‑grown embryo culture plants had higher Fv/Fm compared to the nursery raised plant. This increase in Fv/Fm during acclimation indicated the increase in photochemical activity and photosystem II electron transport efficiency. The study indicated increase in photosystem efficiency and carbon assimilation efficiency of embryo cultured plantlets of coconut during acclimatization.

Abstract:

As an important part of children’s literature, nursery rhymes are the earliest literary styles that children are exposed to after they are born. They can reflect objective things, living customs and national culture. Through the comparison of animal images in Chinese and English classic nursery rhymes, this paper concludes that there are cultural differences in animal images in nursery rhymes. Some animal images have similar cultural connotations in Chinese culture and English culture, while some animal images have different cultural connotations.

Abstract:

Pest attack, disease and soil fatigue have always been a great problem in fig (Ficus carica L.) nursery tree production, especially when traditional methods that use soil culture are applied. Therefore, as an alternative method, substrate culture could be a sustainable and favorable propagation method for growing healthy nursery fig trees of high quality. No information is available on substrate use and its effect on nursery fig tree production. The present study was aimed to define a favorable substrate to cultivate nursery fig trees in substrate culture, and to examine the effects of substrates on morphological and biochemical characteristics of the fig trees by growing plants in a high-tunnel. Fig cv. "Sarilop" (Calimyrna) cuttings were used in this trial as plant material. Three growth media based on perlite (100%), peat (50%) + perlite (50%), and fine sawdust (100%) were tested using soil as a control. Plants were grown in trough culture from the day of planting cuttings up to the uproot point of fig nursery trees, during eight months, and they were not transplanted into another medium during the growing period. To observe the effect of substrates on the nursery fig trees, some morphological and biochemical characteristics were determined. The use of peat + perlite and perlite led to increased plant growth and quality of fig nursery trees grown in high-tunnel.

Abstract:

The increasingly common use of English nursery rhymes intertextually has impacted upon their transfer into target cultures: entire nursery rhymes, fragments and characters are now found in translational situations. Most of these situations are adaptations of nursery rhymes into other media; and one of the most evident is the use of nursery rhyme characters found in a different context, frequently portrayed visually. Through a reception case study with Spanish students, this report intends to address issues about the relevance of intertextuality in translation, as well as the child’s assumptions in relation to discourse and visual input. Through a qualitative mixed-method study, children worked with nursery rhymes without visual prompts as well as intertextually presented nursery rhyme characters, and offered insight into acquired expectations and anticipations. Through the revision of the results, visual adaptation proves to contribute to children’s acculturation and assumptions, reducing the openness to foreignization. Key words: adaptation, intertextuality, nursery rhymes, translation, acculturation ResumenEl uso cada vez más común de las nursery rhymes inglesas de forma intertextual tiene un impacto sobre su transferencia a la cultura meta: rimas enteras, fragmentos o personajes se encuentran ahora en situaciones de traducción. Muchas de estas situaciones son adaptaciones de nursery rhymes a otros medios; y una de las más evidentes es el uso de personajes de nursery rhymes en un contexto diferente, normalmente con un apoyo visual. A través de un estudio de recepción con estudiantes españoles de edades comprendidas entre 12 y 14 años, este artículo pretende ofrecer respuestas sobre la relevancia de la intertextualidad en la traducción, además de las presuposiciones en relación al discurso y a los mensajes visuales. A través de un estudio de métodos mixtos, un grupo de participantes trabajó con nursery rhymes sin apoyo visual y con personajes de nursery rhymes presentados de forma intertextual y con apoyo visual. El estudio ofrece información sobre las expectativas adquiridas y los patrones discursivos de los niños y adolescentes. En la revisión de los resultados, se demuestra que la adaptación visual influye en la aculturación y las presuposiciones de los niños partiendo de un modelo hegemónico, y reduce su capacidad de extranjerización en transferencias culturales.

Abstract:

Hosta ×hybrid Tratt. `Blue Cadet' and Hosta tokudama Tratt. `Newberry Gold' were micropropagated in shaken liquid culture and on agar media, in conventional vessels and vessels modified for ventilation in vitro. Acclimatization under intermittent mist and growth in an outdoor nursery during the late spring and summer were monitored by dry weight analysis of sample plants every 4 days for a 60-day period (ex vitro growth). Results for `Newberry Gold' were 1) in vitro shoot growth was greater in liquid than agar culture, regardless of vessel; 2) shoots from agar or liquid culture grew at similar rates ex vitro; 3) ex vitro root growth was greater for liquid than agar cultured plants, regardless of vessel type. Results for `Blue Cadet' were 1) in vitro and ex vitro shoot growth was greater in liquid than agar culture regardless of vessel type and 2) ex vitro root growth was greatest for liquid cultured plants from conventional vessels. Ventilated vessels were generally beneficial for agar but not liquid culture. Benefits of liquid culture for micropropagation of Hosta found in vitro are at least maintained and sometimes enhanced during ex vitro growth in the mist bed and nursery.

Abstract:

Evaluation of rice for resistance to rice blast disease caused by Pyricularia grisea usually is conducted in upland (nonflooded) disease nurseries, although all commercial U.S. rice is produced under flood irrigation. Upland rice is more susceptible to leaf blast than is flooded rice, and the magnitude of this differential susceptibility can vary among cultivars. This 2-year study was undertaken to determine (i) the relationship between rates of disease development (slow-blasting) in upland and flooded rice and (ii) the value to a rice breeding program of establishing a flooded blast nursery, a facility far more difficult to manage than an upland nursery. Among 200 rice lines compared for leaf blast susceptibility under upland and flooded cultures, only 7 were rated as slightly more resistant under upland culture and 136 rated more resistant under flooded culture. Disease ratings under upland and flooded cultures were highly correlated (R = 0.819). Among 14 preselected cultivars over 2 years, disease development curves under upland and flooded cultures were highly correlated (R = 0.990). The cultivars with intermediate susceptibility under upland culture appeared to benefit most from flooded culture. Upland culture provided more opportunities to assess slow-blasting than did flooded culture, since many lines that produced susceptible-type lesions in upland culture failed to do so under flooded culture. It was concluded that adequate information on comparative leaf blast resistance among rice lines was attainable from upland blast nurseries and that routine evaluation of rice breeding lines for blast resistance in flooded nurseries was not necessary.

Abstract:

The nursery stages of mud crab, genus Scylla, proceed from the megalopa stage to crablet instar stages. We review the definition and several of the key stages in mud crab nursery activities. The practice of the direct stocking of megalopa into ponds is not recommended due to their sensitivity. Instead, nursery rearing is needed to grow-out mud crabs of a larger size before pond stocking. Individual nursery rearing results in a higher survival rate at the expense of growth and a more complicated maintenance process compared with communal rearing. The nursery of mud crabs can be done both indoors or outdoors with adequate shelter and feed required to obtain a good survival percentage and growth performance. Artemia nauplii are still irreplaceable as nursery feed, particularly at the megalopa stage, while the survival rate may be improved if live feed is combined with artificial feed such as microbound diet formulations. Water quality parameters, identical to those proposed in tiger shrimp cultures, can be implemented in mud crab rearing. The transportation of crablets between different locations can be done with or without water. The provision of monosex seeds from mud crab hatcheries is expected to become commonplace, increasing seed price and thus improving the income of farmers. Numerous aspects of a mud crab nursery including nutrition; feeding strategies; understanding their behaviour, i.e., cannibalism; control of environmental factors and practical rearing techniques still need further improvement.

Abstract:

Abstract A comparative study on the nursery culture of the spat of the tropical oyster, Crassostrea iredalei, in an earthen pond and a mangrove canal was conducted over two months. The results revealed no differences in the absolute growth rate determined by shell width between the two culture sites (P < 0.05). Sub-adult oysters cultured in the mangrove canal showed a higher absolute growth rate in shell length and a higher daily growth rate than the oysters cultured in the earthen pond (P < 0.05). The mean survival rate of sub-adult oysters cultured in the earthen pond (99.8 ± 0.2%) was significantly higher than for those cultured in the mangrove canal (66.7 ± 31.4%). Decreased density from the loss of sub-adult oyster nursery culture in the mangrove canal led to higher growth performance than in the earthen pond. However, no difference was found for the fraction of oysters larger or smaller than 5 cm for the two culture sites (P < 0.05). A significant difference was noted in the Condition Index (CI) between the two culture sites (P < 0.05). The high primary productivity in mangroves is a major supporter of higher CI in sub-adult oysters cultured in mangrove canals versus in earthen ponds. Water exchange in the earthen pond to maintain calcium and magnesium concentrations resulted in no differences in the shell compressibility of sub-adult oysters compared with those cultured in the mangrove canal.

Abstract:

High production costs in grouper nursery can be caused by the use of large fingerlings size and long rearing times. The purposes of this study were to evaluate the culture performance and economic profitability of “cantang” hybrid grouper juveniles reared at different initial stocking sizes and nursery periods. This research lasted from September to December 2017 in one of small scale hatcheries in Buleleng, Bali, Indonesia. This study consisted of two experimental treatments; the first treatment was different initial stocking sizes (body weight and total length) of 0.50 ± 0.07 g and 3.0 ± 2.1 cm; 3.50 ± 0.67 g and 5.0 ± 1.9 cm; and 6.10 ± 0.91 g and 7.0 ± 2.3 cm. The second treatment was different nursery periods with the following arrangement: 15, 30, and 45 days (initial body weight and length of 0.54 ± 0.067 g and 3.0 ± 0.09 cm, respectively). The stocking density in all treatments was 1,000 fish reared in a 2 m x 2 m x 1 m concrete tank. The observed culture performance parameters consisted of survival rate (SR, %), daily growth rate (DGR, g/day), and feed conversion ratio (FCR). The calculated economic profitability parameters were net profit, return-on-investment (ROI, %), and return cost ratio (R/C). The highest culture performance was achieved by the juveniles reared using the largest initial stocking size and longest nursery period. This was in contrast with the economic profitability, in which smaller initial stocking size and middle nursery period had resulted in the highest profit. Based on the culture performance and profitability considerations, the suggested combination of initial stocking size and nursery period for cantang fingerlings is 3.0 ± 2.1 cm initial stocking size and 30 days rearing times.

Abstract:

To observe the effectiveness of short time in-pond nursery of post larvae (PL) on the survival rate and production of shrimp (Penaeus monodon) under modified improved culture system, an experiment was conducted in earthen ponds at Brackishwater Station of Bangladesh Fisheries Research Institute, Khulna. Results of the experiment revealed that short time in-pond nursery of PL provided the significantly higher (p<0.05) survival rate (58%) than direct stocking of PL (47.81%) in the rearing pond. In-pond nursery of PL provided 9.95% better survival rate than direct stocking. The production of shrimp was 661 kg/ha under in-pond nursery of PL and it was 534 kg/ha under direct stocking of PL in rearing ponds. The production of shrimp was also significantly higher (p<0.05) under in-pond nursery system than direct stocking of PL in rearing ponds. Final weight gain and Food Conversion Ratio (FCR) values were similar in both the treatments. Water quality parameters in both stocking systems were insignificant and it was within the range of shrimp culture. In this study, the increment in production under in-pond nursery system was mainly due to the increase of survival rate in the respective treatment was ascertained.DOI: http://dx.doi.org/10.3329/pa.v19i2.16958 Progress.

Abstract:

Phytophthora ramorum, cause of Ramorum blight on numerous woody ornamental shrubs, is a regulated pathogen in the US and internationally. Currently, nurseries are inspected to detect infected plants; however, many plants are propagated by tissue culture nurseries and the behavior of P. ramorum in this system is unknown. Pathogen growth and sporulation in propagation vessels containing different multiplication and rooting media, with a range of plants and without plants, was evaluated with regard to pathogen visibility and induction of disease symptoms. Within 2 weeks, the pathogen colonies were visible to the naked eye on all 26 multiplication media and on 9 of 11 rooting media tested (without plants). The appearance of colonies on different media was variable and no sporangia but occasional chlamydospores were produced. The pathogen growth was very visible on multiplication media containing susceptible plants, inoculated plants exhibiting obvious discoloration and mortality. The pathogen was reisolated from terminal shoot tissue and roots of symptomatic plants. Variability occurred in susceptibility of different cultivars of a plant species, in virulence of the two isolates of the pathogen, and in recovery from shoot tissue. We conclude that fungal growth on the media, with or without plants, and symptoms of disease were apparent enough that contaminated vessels would be destroyed. Accepted for publication 9 April 2007.

Abstract:

Plant growth and nutrient uptake response to increased fertilization can be conceptually described by cur vi linear relationships depicting phases of nutrient deficiency, sufficiency, luxury consumption, and toxicity to rationalize fertilizer prescriptions and improve nutrient diagnosis. We validated this model to determine optimum nitrogen storage of young black spruce (Picea mariana (Mill.) BSP). Container seedlings were supplied with a mixed nitrogenphosphoruspotassium (NPK) fertilizer at rates ranging from 0 to 80 mg N/seedling and reared in a greenhouse for one growing season. Plant growth and nutritional parameters of the plants exhibited classic responses of N deficiency, luxury consumption, and toxicity that were corroborated by vector diagnosis and appeared consistent with the conceptual model. Seedling biomass production was maximized at sufficiency (30 mg N/seedling), whereas N content of tissues peaked at the optimum loading rate (64 mg N/seedling). Toxicity occurred at the 80 mg N/seedling dose rate that increased plant N concentration (5%) but reduced growth (17%) and N content (14%) relative to the optimum level. Plant N content was raised 150% by optimum loading, exemplifying the effectiveness of this practice for building internal N reserves prior to planting. The newly validated model will help refine fertilizer recommendations and nutrient diagnosis for other species or cultural systems.

Abstract:

Animal metaphors are commonly seen in daily language and often appears in nursery rhymes. With the Great Chain of Being as the theoretical framework, this study deeply analyzes and compares the animal metaphors in 896 Cantonese and English nursery rhymes from the cognitive linguistic perspective by classifying them and interpreting their formed images. It is found that the number of animal metaphors in Cantonese nursery rhymes is much higher than that in English nursery rhymes for Cantonese is a dialect of the Chinese language, which belongs to imagery languages. Besides, although in some way animal metaphors in Cantonese and English nursery rhymes are similar from the perspective of their educational functions, due to the cultural differences between the Cantonese-English ethnic groups, animal metaphors in Cantonese and English nursery rhymes present the cultural characteristics of Cantonese and English respectively in terms of the source domains, their metaphorical connotation and mappings. This study may provide some reference for the translation and inheritance of Cantonese and English nursery rhymes, helping to pass down and communicate the local culture, so as to realize the purposes of creating and spreading nursery rhymes.

Abstract:

The genus Vaccinium represents an increasingly important group of plants for the U.S. green industry. In 2012, blueberries (Vaccinium sp.) ranked the second most important berry crop in the U.S. with a total crop value over $780 million. The popularity of blueberries creates opportunities as well as challenges for nursery crop producers. This article presents a review of current nursery production practices of blueberry and explores the challenges and opportunities for nursery crop producers, including pesticide use during nursery production of an edible crop, and discusses current research relevant to the green industry. Needs for additional research and opportunities for breeding are presented. Blueberries are Ericaceous plants and have very specific cultural requirements. This review presents the culture, as well as insect, mite, and disease control from an integrated pest management (IPM) approach for several blueberry species. A serious threat to the blueberry market, spotted wing drosophila (Drosophila suzukii Matsumura) is discussed to provide information needed by commercial producers and landscape managers to address client and customer questions. This review also highlights the most relevant blueberry selections for container production in the southeastern United States.

Abstract:

The objectives of this study were: to identify nursery cohorts with an active Salmonella infection using combined serological and bacteriological methods, and to try to identify risk factors associated with swine nurseries with active Salmonella spread. Twenty pigs from each of 50 cohorts of weaned pigs from 44 different nursery barns were sampled about the time of weaning and near the end of the nursery stage. Information regarding farm management and biosecurity practices were collected using a questionnaire. Blood samples were obtained at both visits, while rectal swabs were collected at the second visit. An enzyme-linked immunosorbent assay (ELISA) was used to test sera for Salmonella antibodies and rectal samples were cultured for Salmonella. A nursery cohort was identified as having an active Salmonella infection if Salmonella was cultured from one or more of the 20 pigs or if serological evidence suggested exposure to Salmonella. The association between farm-level management covariates and active Salmonella infection was assessed in 46 cohorts using a logistic regression model. Nine of 46 (20%) cohorts produced Salmonella-free pigs. The remaining 37 (80%) cohorts were classified as having an active infection. Examination of risk factors failed to identify how negative and positive nurseries differed.

Abstract:

Bivalve spat were grown in an on-shore upwelling nursery using a landlocked heliothermic marine basin (Norwegian oyster-poll) as a food production system and thermal source. Several manipulations, involving artificial fertilization (N, P and Si), were performed in order to enhance the production capacity. Based on data from a monitoring programme (May-August) on physical, chemical and biological variables in the system, main paths of nitrogen flow and dynamics of bivalve production and nitrogen conversion efficiency were described. The conversion efficiency of the system, bivalve N production over estimated new N, of which 86% was fertilizer nitrogen, was 16·2% for the experimental period of 93 days. During this period the decrease in efficiency from levels of 22–25% to 8% was probably due to the transition from nitrate-limited to light- and grazing-limited phytoplankton production. The food utilization efficiency, bivalve N production over available particulate N in the nursery, was 19·8% for the experimental period. The efficiency increased in July from 19·4% for the first two weeks to 27·0% during late July. This was probably due to a higher food value of the phytoplankton community in late July, dominated by Skeletonema costatum (Bacillariophyceae) and Nitzschia sp., than the phytoplankton community in early July, dominated by Fragilaria sp.

Full text

Abstract:

The influence of short-day (9 h) and long-day photoperiods (18 h), and three levels of plant moisture stress (none and dried to predawn shoot water potentials of −1.0 or −1.8 MPa), applied for 7 weeks beginning in mid-July 1990, were studied on greenhouse-grown stecklings (rooted cuttings) of yellow cypress (Chamaecyparisnootkatensis (D. Don) Spach). A series of morphological and physiological measurements were made on the stecklings during and after the treatment period. Moisture stress significantly reduced steckling shoot growth and shoot dry weight by lowering net photosynthesis rates, while short-day photoperiods did not. The most pronounced growth reductions occurred when the treatments were combined, but effects were short-lived, with shoot growth resuming soon after the treatments ended. The short-day and moisture-stress treatment had no significant effect on root dry weight, shoot/root ratio, or water balance ratio. The risk of using moisture stress to control shoot growth in the nursery was low; mortality did not occur until the stecklings had been without water for at least 9 days. Moisture-stress treatments increased steckling root growth potential but had little effect on osmotic adjustment, cell elasticity, dry weight or symplastic fractions, cuticular transpiration, resistance to plant water movement, and relative water content of the shoots; short-day treatments had no influence on any of these parameters. Short days and moisture stress, singly or combined, had little effect on steckling cold hardiness. Steckling gas exchange rates were reduced significantly by low root temperature. In a 6-week controlled-environment simulation of planting-site moisture conditions, no significant differences in steckling net photosynthesis, transpiration, or stomatal conductance were found among nursery treatments; those that had been subjected to moisture stress in the nursery had small growth increases after planting in both wet and dry soil moisture regimes. We conclude that shoot growth of yellow cypress stecklings was controlled in the nursery using 9-h photoperiods and −1.8 MPa predawn shoot water potentials. Improved cold hardiness of the stecklings was not achieved using these nursery cultural methods, but moisture stress did confer some measure of drought resistance immediately after treatment, with higher root growth potential and lower shoot mass.

Abstract:

Abstract Topdressing of urea (224 kg/ha) in combination with Glomus mosseae inoculum produced the largest 1-0 yellow-poplar (Liriodendron tulipifera L.) seedlings of 16 combinations of nursery fertilizer and endomycorrhizal treatments. However, after two years in an outplanting trial, significantdifferences in seedling size due to the nursery treatments had disappeared. The cause was traced to soil variability; five different soils were found within the 0.5 ha test site, varying in characteristics known to be important to yellow-poplar growth. Soil properties had occluded significanteffects of nursery culture treatments on seedling height growth and the effects continued through the fourth growing season. South. J. Appl.

Abstract:

Abstract Height, number of roots, root length, and shoot quality rating on loblolly pine (Pinus taeda L.) tissue culture plantlets were measured in the laboratory and related to subsequent nursery and field performance. Shoot quality rating was the most important characteristic and was most consistently correlated with nursery and field traits. These results imply that only plantlets with the best shoot quality rating should be used so that growth rates will be similar to seedlings.

Abstract:

A morphological and anatomical study of the mycorrhizas on Pinus strobus L. was conducted on seedlings excavated from St.-Williams nursery in southern Ontario. Micro- and macro-scopic characters were used to classify the morphotypes into complexes and, when possible, genera and species. An E-strain fungus, fungi from the Mycelium radicis atrovirens (MRA) complex, and an unidentified ascomycetous "red-type" fungus formed ectendomycorrhizal (EECM) associations, while Tuber sp., Hebeloma sp., and Thelephora terrestris formed ectomycorrhizal (ECM) associations in the nursery. Cultures of Hebeloma sp., the E-strain fungus, Tuber sp., and two morphologically distinct MRA fungi (MRA1, later identified as Phialophora finlandia Wang & Wilcox, and MRA2, unidentified) were isolated from field-collected morphotypes and re-inoculated onto Pinus strobus seedlings grown in semisterile pot cultures for 4 months. In the resynthesis experiment, the E-strain fungus formed EECM with sparse intracellular colonization, and Tuber sp. formed ECM with characteristic cystidia and densely packed mantles, as they had in the field. However, unlike the MRA field specimens, Phialophora finlandia formed ECM in pot culture. Hebeloma sp., normally an ECM former with conifer seedlings, did not form mycorrhizal structures under the given culture conditions, and neither did the MRA2 isolate. Key words: ectomycorrhiza, ectendomycorrhiza, Pinus strobus, Tuber sp., Phialophora finlandia, E-strain.

Abstract:

The nursery/landscape industry has been one of the fastest growing agricultural sectors in Canada. Since 1980s, the Ornamental Nursery Research Program at the Horticultural Research Institute of Ontario (HRIO) has been conducting research which focuses on environmentally friendly production practices. Emphasis is on the use of composted or uncomposted organic wastes as amendments in container potting mixes. Various projects have evaluated mixes derived from wastes such as spent mushroom compost, paper mill sludge, apple pomace, and various types of barks. In the late 1980s and early 1990s, the scope of the research expanded to include composting and a wider assortment of wastes such as waxed corrugated cardboard, municipal solid waste compost, wood chips from pallets and furniture and demolition wastes, food wastes, and organic fertilizers manufactured from meat by-products, and selected industrial wastes. Presently, paper mill sludge is being evaluated as field soil amendment for growing nursery shade trees and also for use in rehabilitating marginal, non-agricultural land.

Abstract:

Studies were conducted on the comparative growth and morphology of Populustrichocarpa (T), P. deltoides (D), F1 hybrids (T×D), F2 hybrids (TD × TD), and B1 hybrids (T × TD, TD × T) at one nursery and two plantation sites in western Washington and Oregon. First coppice resprouts in the nursery showed intermediacy of the F1 and F2 between parentals in four of five morphological leaf traits measured, and intermediacy of B1 values between F1 and T in three. Amounts of variation generally conformed to the model of F2 > B1 > F1. The percent significant trait correlations were 11.6 for the F1, 8.7 for the B1, and zero for the F2. No simply inherited traits were identified. Growth in the first and successive coppices in the nursery was significantly greater in the F1 than in the B1 and F2 generations. The same trend was observed in two field tests at Pack Forest, Washington and Westport, Oregon in which 691 and 381 clones from 60 and 42 families, respectively, gave a rank order in 4-year volume growth of F1 > B1 > T > F2 > D. Several F1 families and clones showed high rank consistency between years and locations. The results confirm earlier studies and are discussed in relation to the mechanisms that underlie T × D hybrid superiority.

Abstract:

Exochorda racemosa is an ornamental shrub with white flowers that is spiraea-like, deciduous, and hardy. The buds resemble pearls. Normally it is propagated by seeds, layers, and cuttings of softwood. However, it is a slow process that takes a few years to produce a reasonable size plant for the demanding market. Our objective was to establish a successful in vitro culture and to rapidly multiply this ornamental species. Softwood explant materials were collected from a local nursery and were disinfested with 15% bleach solution and rinsed three times with sterile distilled and deionized water. In vitro cultures were established and maintained in woody plant medium (WPM) supplemented with BA at 0.1 mg·L-1, 3% sucrose, and 0.7% agar with the pH adjusted to 5.8. Then shoots were transferred to the multiplication medium containing BA, CPPU, or thidiazuron (TDZ) at various concentrations. Preliminary results show that explants cultured on medium containing TDZ produced the best shoot proliferation.

Abstract:

The efficiency of in vitro anther culture was screened in a full diallel population of four spelt wheat genotypes and ten F1 hybrids. Genotype dependency was observed based on the data of embryo-like structures (ELS), green-, albino plantlets. In the diallel population and ten F1 hybrids, the green plantlets production ranged from 13.75 to 85.00 and from 6.30 to 51.00, respectively. The anther culture-derived plants of F1 hybrids were grown up in the nursery. At the harvest, 436 spontaneous doubled haploid (DH) plants were identified among the 1535 anther culture-derived transplanted and grown up individual plants. The mean of spontaneous rediploidization was 28.4% which ranged from 9.76% to 54.24%. In two consecutive years, the agronomic values of ‘Tonkoly.pop1’ advanced line were compared with seven DH lines of ‘Tonkoly.pop1’ in the nursery. The DH lines achieved competitive values in comparison with ‘Tonkoly.pop1’ advanced line based on the 11 measured parameters (heading date, plant height, yield, hardness, width and length of seed, TKW, hulling yield, flour yield, protein and wet gluten content). These observations presage the efficient utilization of anther culture in spelt wheat breeding.

Abstract:

The cassava residue was selected as carbon source to study the effect of biofloc technique (BFT) on water quality control, growth performance and seedling emergence in a 40 L culture water of litopenaeus vannamei nursery culture system. The BFA groups included Graded level of C/N (15/1, 20/1 and 25/1) with three parallel samples, compared to the control groups. At the end of the feeding trial 15 days, 10.7%, 14.4% and 46.8% significantly decreased in NH4+-N concentration of the graded level of C/N (p<0.05); 80.2%, 96.0% and 96.2% distinctly decreased in NO2--N concentration (p<0.05); 81.4%, 57.8%, 151% obviously increased on seedling emergence (p<0.05) and 52.2%, 80.8%, 18.2% obviously increased on body weight (p<0.05). The present study elucidates that in the nursery system adding cassava residue as carbon source the culture water quality was evidently improved and heterotrophic bacterium, phytoplankton and zooplankton was also effectively obviously promoted.

Abstract:

Sea cucumber Holothuria scabra has high market value and demand, consequently its stock has sharply declined due to overexploitation. Aquaculture of sea cucumbers is a key to conserve and to restore the decreasing population while producing them for commercial purpose. The obstacles in scale-up production are still need to be addressed in nursery stage, juvenile release techniques and grow out which can be implemented in pond culture. Growth performance of H. scabra juvenile cultured in floating hapas was investigated in pond in Sekotong, West Lombok. In 12 weeks of field trial, the effect of three different initial groups of juvenile: small (1.42 + 0.01 g ind-1), medium (3.42 + 0.02 g ind-1) and big (7.77 + 0.02 g ind-1) were tested on their growth and survival by Completely Randomized Design. The result showed both Specific Growth Rate and Weight Gain were higher in small group (2.57 + 0.11 ‰d-1 and 2.57 + 0.11 %, respectively). The highest survival rate was in the biggest initial size group. Pond in Sekotong, West Lombok is potential for nursery and grow out of H. scabra juvenile.
