Abstract:

Seleksi cekaman salinitas kacang tanah dilakukan untuk mendapatkan tetua yang toleran terhadap salinitas dan memperbaiki sifat kacang tanah dalam kegiatan pemuliaan tanaman. Informasi genotip unggul kacang tanah toleran terhadap salinitas sangat diperlukan sebagai dasar pemilihan genotip tetua yang adaptif pada lahan salin. Penelitian ini bertujuan untuk memperoleh kacang tanah yang memiliki sifat toleran cekaman salinitas dan menentukan konsentrasi air laut yang dapat ditoleransi oleh tanaman. Penelitian ini dilaksanakan di Kebun Percobaan dan Penelitian, Jurusan Agroteknologi, Fakultas Pertanian Perikanan dan Biologi, Universitas Bangka Belitung, pada bulan Februari–April 2018. Penelitian menggunakan Rancangan Acak Lengkap (RAL) pola split plot dengan 2 ulangan. Petak utama adalah tingkat salinitas yaitu non-salin (kontrol), salinitas rendah, dan salinitas sedang. Anak petak adalah 5 genotip kacang tanah yaitu aksesi lokal (Belimbing dan Arung dalam) dan varietas nasional (Tuban, Kancil, dan Hypoma). Hasil penelitian menunjukkan bahwa varietas Hypoma memiliki karakter jumlah daun dan diameter batang yang paling baik, namun tidak toleran terhadap cekaman salinitas sedang. Aksesi Belimbing merupakan genotip toleran salinitas rendah berdasarkan nilai indeks toleransi cekaman salinitas. Selection of groundnut tolerant to salinity stress is carried out to obtain parent genotypes tolerant to salinity and improve the characteristics of groundnut in plant breeding program. The information of superior groundnut genotypes tolerant to salinity is necessary as the basic of genotypes selection adaptive in the saline area. The research aimed to obtain the groundnut tolerant to salinity stress and determine the concentration of seawater that can be tolerated by groundnut. This research was conducted at The Experiment and Research Field, Faculty of Agriculture Fisheries and Biology, University of Bangka Belitung, from February to April 2018. The research used Complete Randomized Design (CRD) split plot with two replications. Main plot was concentrations of seawater; non-saline (control), low salinity, and moderate salinity. The subplot was groundnut genotypes of local accessions (Belimbing and Arung Dalam) and national varieties (Tuban, Kancil, and Hypoma). The results of this research indicated that Hypoma has the best result for plant height and diameter of stem, but intolerant to moderate salinity stress. Belimbing was the genotype with low salinity tolerance based on score index of tolerant salinity stress.

Abstract:

Water salinity control in interstate basins is exercised by means of treaties. Such is the case of the Colorado River in Argentina by the Treaty of 26 October 1976. However, environmental restoration of soil, flora and water requires constant adjustment, which can be made by agreements that render this possible, or by political decisions that will prevent conflicts among the states.

Abstract:

Abstract Most commercial citrus varieties are intolerant of salinity stress, but some rootstocks, such as Rangpur lime, tolerate moderately saline irrigation water. Development of salinity-tolerant citrus may allow for citriculture in semiarid and arid regions where salinity stress is problematic. Because salinity stress influences shoot growth in citrus, we compared the behavioral responses of Asian citrus psyllid, Diaphorina citri Kuwayama, to salinity-stressed versus nonstressed Rangpur lime seedlings. The effects of salinity stress on key physiological processes in the seedlings were also examined. Seedlings in the control group were fertilized with a solution having a salinity of 1.7 dS m−1 while seedlings in the salinity-stressed group were fertilized with a solution having a salinity of 10 dS m−1. The seedlings were exposed to salinity stress for increasing durations (15, 20, or 60 d). Seedlings presented differential physiological responses 15 d after the imposition of salinity stress, and differences in psyllid settling rate on control versus salinity-stressed seedlings were discernable within 1 h following the imposition of salinity stress. The levels of settling, oviposition, and egg survivorship were significantly lower on salinity-stressed versus control seedlings. Olfactometer tests showed that female psyllids preferred the odor from control seedlings, suggesting that the odors of control and salinity-stressed seedlings were different. The results showed that D. citri avoids salinity-stressed seedlings; this suggests the possibility of using moderate salinity stress as a management strategy to minimize psyllid settlement and reproduction and to reduce the spread of huanglongbing, especially in citrus grown in semiarid and arid areas.

Abstract:

With increasing salinity in irrigation areas, the option of tree planting in areas with shallow groundwater is seen as an ‘environmentally friendly’ alternative for controlling salinity. This study uses simulation modelling to investigate the long-term effects of planting Eucalyptus grandis in irrigated areas with shallow and saline watertables in the Riverine Plains where concerns exist about salinity effects on irrigated agriculture. APSIM, a 1-dimensional model of the soil–water–plant system, was modified to describe the interaction between the watertable within the plantation with the, normally shallower, watertable in the surrounding irrigated pasture. The model was tested against measured data and then used to simulate a range of different environmental conditions (depth and salinity of the groundwater, soil) and management options (irrigation with different amounts and salinity). The results of a total of 702 simulation runs helped to identify conditions in which irrigated plantations may be viable and how the irrigation of these plantations may be managed to decrease the impact of salinity on tree growth. The results indicated that if irrigation is to improve productivity, it must be in large amounts (1000 mm or more) and of good quality to have a significant effect on tree production. Irrigation with low salinity water (EC <2 dS/m) can only be used to reliably increase production in conditions where there are deeper watertables (4 m or deeper) on fast-draining soils. In these cases, flexible irrigation practices (scheduled irrigation) need to be employed in order to manage the salt levels within the tree root-zones. The viability of plantations is likely to decrease with increasing irrigation water salinity as salt accumulation in the profile reduces the ability of the trees to act as natural sinks. Depending on the irrigation and groundwater salinity, trees might be effective only up to a few years (as little as 9 years). Optimum response of trees to irrigation is only predicted with fresh water and scheduled irrigation (up to 1700 mm/year). However, if ample fresh water was available, other higher value cropping options are likely to be sought by land managers. Furthermore, the large amounts of water added to the plantation will have negative effects (water and salt export from the plantation) on the surrounding land, which will need further intervention to be sustainable.

Abstract:

Parmi les contraintes abiotiques la salinité est considérée comme un problème majeur, qui affecte le fonctionnement des plantes, en particulier leur croissance et leur rendement. Afin d’étudier le contrôle génétique de la tolérance à la salinité chez Medicago truncatula, plante modèle de la famille des légumineuses, deux expérimentations ont été réalisées. La première expérimentation visait à étudier l’effet de la contrainte saline sur différents paramètres morpho-physiologiques pour un panel de génotypes de M. truncatula afin de déterminer les traits de phénotypage pour la tolérance à la salinité. Les génotypes A17, TN1.11, DZA315.16, A20, TN1.12 et F83005.5 ont été sélectionnés parmi des lignées originaires de différents pays méditerranéens, qui ont été déjà séquencées (http://www1.montpellierinra.fr/BRC-MTR/mauguio/mauguio.php). Les génotypes ont été étudiés sous 6 traitements salins (0, 30, 60, 90,120 et 150 mM NaCl) dans un essai factoriel sous forme de blocs complets aléatoires en trois répétitions. L’analyse de la variance montre des différences significatives entre les niveaux de salinité et une interaction entre les génotypes et les traitements salins concernant la plupart des caractères étudiés. Le génotype « DZA315.16 » présente les valeurs les plus importantes concernant les effets principaux pour les caractères morphologiques alors que « TN1.11 » présente les valeurs les plus faibles. La projection verticale de la surface foliaire de la plante (Leaf Area=LA), significativement corrélée à la biomasse des plantes, apparaît comme un trait d’intérêt pour le phénotypage de la tolérance à la salinité. La concentration saline la mieux adaptée pour démontrer les différences parmi les lignes étudiées se situe entre 90 et 120 mM NaCl. Le génotype « TN1.11 » contrairement à « DZA315.16 » et à « Jemalong-A17 » présente un maintien de la surface foliaire de la plante en réponse à la salinité. Pour la deuxième expérimentation, une population de cent lignées recombinantes (Recombinant Inbred Lines=RILs) produite par le croisement entre « TN1.11 » et « Jemalong-A17 » a été retenue pour l’analyse du contrôle génétique de la tolérance à la salinité. Les RILs ont été développés par la méthode de descendant mono graines (Single Seed descent= SSD) jusqu’ à la génération F6 à l’INP-ENSAT, France. Le plan d’experimentation est « Spli plots » , sous forme de blocs randomisés avec trois répétitions et deux conditions : traitement salin (100 mM NaCl) et témoin (eau). L’expérience a été menée pour déterminer la variabilité génétique et pour identifier les QTLs contrôlant les caractères morphologiques et physiologiques chez la population des lignées recombinantes (RILs). L’analyse de la variance a montré une large variation génétique et une ségrégation transgressive pour les caractères étudiés. La différence entre la moyenne des RILs et la moyenne de leurs parents n’est pas significative concernant tous les caractères étudiés dans les deux conditions, ce qui montre que les RILs utilisées dans notre expérimentation sont représentatives de toutes les lignées recombinantes possibles du croisement « TN1.11 x Jemalong-A17 ». 21 QTLs ont été détectés dans la condition témoin et 19 QTLs ont été identifiés sous contrainte saline (100 mM NaCl). Le pourcentage de la variance phénotypique expliqué par les QTLs varie entre 4.60% et 23.01%. Certains de ces QTLs sont spécifiques à la condition saline, ce qui démontre l’existence du contrôle génétique de la tolérance à la salinité chez M. truncatula ; tandis que les autres ne sont pas spécifiques et contrôlent un même caractère dans les deux conditions. Des QTLs superposés concernant différents caractères ont été aussi observés. Les résultats fournissent des informations importantes en vue de futures analyses fonctionnelles de la tolérance à la salinité chez M.truncatula et pour d’autres espèces voisines
Among abiotic stresses salinity is considered as a serious problem affecting plant functions especially growth and yield. In order to study the genetic control of salt stress in the model legume Medicago truncatula, two experiments were performed. The first experiment was conducted to study the effect of salt stress on some morpho-physiological parameters in M. truncatula genotypes and to determine the eventual use of some traits as tolerance criteria. Genotypes including A17, TN1.11, DZA315.16, A20, TN1.12 and F83005.5 are selected through a sequenced lines collection (http://www1.montpellierinra.fr/BRC-MTR/mauguio/mauguio.php) which are originated from different Mediterranean countries. Genotypes were studied under 6 salinity treatments (0, 30, 60, 90,120 and 150 mM NaCl) in a factorial design based on randomized complete blocks with three replications. Analysis of variance show significant differences among genotypes, salinity levels and interaction between genotypes and salt treatments for most of studied traits. “DZA315.16” genotype presents the highest main effect values for morphological traits whereas”TN1.11” has low values. Vertically projected leaf area (LA); show the highest variability through all studied salt concentrations. The best concentration to find differences between parental lines is 90 to 120 mM Nacl. A segregating population of recombinant inbred lines (100 RILs) of M.truncatula derived from a cross between TN1.11 and Jemalong-A17 was used for the second experiment. RILs were developed by single-seed descent until F6 generation at the INP-ENSAT, France. The experiment was undertaken to determine the genetic variability and to identify QTLs controlling several traits related to plant growth and physiology, in the population of recombinant inbred lines (RILs). Analyses of variance showed a large genetic variation and transgressive segregation for the traits studied. The difference between the mean of RILs and the mean of their parents was not significant for all of the traits in both conditions, showing that the RILs used in our experiment are representative of the possible recombinant lines from the cross TN1.11 x A17. A total of 21 QTLs were detected under control and 19 QTLs were identified under 100mM salt stress conditions. The percentage of total phenotypic variance explained by the QTLs ranged from 4.60% to 23.01%. Some of the QTLs were specific for one condition, demonstrating that the genetic control of a traits differed under control and salt stress conditions. Some others are non-specific and control a trait in both conditions. Overlapping QTLs for different traits were also observed. The results provide important information for further functional analysis of salt tolerance in M. truncatula

Abstract:

[Truncated abstract] The salinisation of agricultural land, urban infrastructure and natural habitat is a serious and increasing problem in southern Australia. Government funding has been allocated to the problem to attempt to reduce substantial costs associated with degradation of agricultural and non-agricultural assets. Nevertheless, Government funding has been small relative to the size of the problem and therefore expenditure needs to be carefully targeted to interventions that will achieve the greatest net benefits. For intervention to be justified, the level of salinity resulting from private landholder decisions must exceed the level that is optimal from the point of view of society as a whole, and the costs of government intervention must be less than the benefits gained by society. This study aims to identify situations when government intervention is justified to manage dryland salinity that threatens to affect road infrastructure (a public asset). A key gap in the environmental economics literature is research that considers dryland salinity as a pollution that has off-site impacts on public assets. This research developed two hydrological/economic models to achieve this objective. The first was a simple economic model representing external costs from dryland salinity. This model was used to identify those variables that have the biggest impact on the net-benefits possible from government intervention. The second model was a combined hydro/economic model that represents the external costs from dryland salinity on road infrastructure. The hydrological component of the model applied the method of metamodelling to simplify a complex, simulation model to equations that could be easily included in the economic model. The key variables that have the biggest impact on net-benefits of dryland salinity mitigation were the value of the off-site asset and the time lag before the onset of dryland salinity in the absence of intervention. ... In the case study of dryland salinity management in the Date Creek subcatchment of Western Australia, the economics of vegetation-based and engineering strategies were investigated for road infrastructure. In general, the engineering strategies were more economically beneficial than vegetation-based strategies. In the case-study catchment, the cost of dryland salinity affecting roads was low relative to the cost to agricultural land. Nevertheless, some additional change in land management to reduce impacts on roads (beyond the changes justified by agricultural land alone) was found to be optimal in some cases. Reinforcing the results from the simple model, a key factor influencing the economics of dryland salinity management was the urgency of the problem. If costs from dryland salinity were not expected to occur until 30 years or more, the optimal response in the short-term was to do nothing. Overall, the study highlights the need for governments to undertake comprehensive and case-specific analysis before committing resources to the management of dryland salinity affecting roads. There were many scenarios in the modelling analysis where the benefits of interventions would not be sufficient to justify action.

Abstract:

Research trials performed in the greenhouse compared the tolerance and response of Hordeum jubatum and desirable pasture grass species to herbicides, salinity, and flooding. Desirable grass species used in this study included: `Fawn' tall fescue (Festuca arundinaceae), `Garrison' creeping foxtail (Alopecurus arundinaceus), `Palaton' reed canarygrass (Phalaris arundinacea), `Climax' timothy (Phleum pratense), `Alkar' tall wheatgrass (Thinopyrum ponticum), `Potomac' orchardgrass (Dactylis glomerata), and `Mustang' altai wildrye (Leymus angustus). Tolerance to herbicides, salinity, and flooding varied significantly among grass species. Herbicide tolerance was tested using four herbicides at five rates each. The herbicides used were imazapic (Plateau), propoxycarbazone (Olympus), sulfosulfuron (Outrider), and flucarbazone (Everest) at rates of 0, 10, 25, 50, 100, and 200 g ha-1. Foxtail barley was least tolerant of sulfosulfuron and propoxycarbazone. Tall fescue, creeping foxtail, and reed canarygrass were susceptible to all the herbicides tested. Timothy and foxtail barley were moderately tolerant while tall wheatgrass exhibited the greatest tolerance to flucarbazone. Orchardgrass was most tolerant to propoxycarbazone. Salinity tolerance was determined by exposing grasses to increasing electrical conductivity (EC) over time. Reed canarygrass and timothy were most susceptible to salinity. Orchardgrass, creeping foxtail, and tall fescue were moderately tolerant of salinity. Foxtail barley, altai wildrye, and tall wheatgrass exhibited the highest tolerances to salinity, and continued to persist at the highest EC levels tested. Flooding tolerance was determined by flooding grasses in 18 cm of water for 2, 4, 6, and 8 weeks. Grasses that were able to extend above the water surface survived, whereas plants that failed to extend beyond the water surface experienced higher mortality rates.

Abstract:

Fisheries management regulations for dusky kob Argyrosomus japonicus, an important commercial and recreational fisheries species, have failed and the stock is considered collapsed. It is important to take an ecosystems approach to management which includes understanding the effect of environmental factors on recruitment, abundance and distribution. The distribution of early juveniles (20-150 mm TL) in the wild appears to be restricted to the upper reaches of estuaries at salinities below 5 psu. Food availability could not explain the distribution of early juveniles. The aim of this study was to investigate the role of salinity on the distribution of early juvenile dusky kob (<150 mm TL) by examining physiological responses of juveniles exposed to a range of salinities under laboratory conditions. The hypothesis was that the physiological functioning of early juveniles would be optimised at the reduced salinities which they naturally occur at. The objectives of this study were to investigate the effect of salinity on: i) plasma osmolality; ii) growth, food conversion ratio and condition factor; and iii) gill histology with emphasis on chloride cell size and number. A preliminary study was undertaken to determine whether the use of 2-phenoxyethanol had an effect on plasma osmolality. Juveniles pithed prior to blood sampling were used as the control. Plasma osmolality was not affected by exposure or duration of exposure (2, 4, 6, 8, 10 min) to 2-phenoxyethanol. The ability of teleosts to regulate plasma osmolality over a wide range of salinities indicates their degree of ‘physiological euryhalinity’. Plasma osmolality of juveniles exposed to 5, 12 and 35 psu was measured every two weeks over a total of six weeks. Although juveniles were able to regulate plasma osmolality over the duration of the experiment, plasma osmolality at 5 and 12 psu was significantly lower than in fish maintained at 35 psu. Growth is used as an indicator of the relative energy used for osmoregulation at different salinities, as the energy used for osmoregulation becomes unavailable for growth. A nineweek growth experiment was conducted on juveniles exposed to 5, 12 and 35 psu. Juveniles grew and survived at all three salinities. However, growth of juveniles at 5 psu was significantly lower than at 12 and 35 psu. Other than a significantly greater weight gain at 35 psu relative to 12 psu, there was no significant difference in specific growth and length gain between juveniles at 12 and 35 psu. Food conversion ratio and condition factor at 12 and 35 psu were not significantly different, but food conversion ratio and condition factor at 5 psu was significantly greater and lower than at 35 psu respectively. In fish, gills are considered the major organ involved in osmoregulation. Within the gills, chloride cells are the predominant site of ion exchange which is driven by the Na⁺, K⁺- ATPase enzyme. Gill samples of juveniles exposed to 5, 12 and 35 psu for six weeks were examined histologically using light microscopy. Chloride cells of juveniles maintained at 5 psu were significantly more abundant than in juveniles at 12 and 35 psu. Chloride cells of juveniles at 5 psu were significantly larger than in juveniles kept at 12 psu, but not significantly different to those of juveniles kept at 35 psu. The ability of the juvenile fish to regulate plasma osmolality indicates that they are 'physiologically euryhaline', but the reduced growth and proliferation of chloride cells at 5 psu suggests that energy expenditure for osmoregulation is increased at hypoosmotic salinities. Salinity induced physiological responses could therefore not explain the natural distribution of early juvenile dusky kob and it is proposed that other environmental factors (e.g. temperature) are also important. It is also hypothesised that the high conductivity of an estuary in South Africa, to which our understanding is limited, may negate the effect of reduced salinity. Although freshwater input into estuaries is an important factor, further investigations to explain the distribution and abundance of early juveniles is required to make management recommendations. Dusky kob is also becoming an increasingly popular aquaculture species in South Africa. In this regard, early juvenile dusky kob can be grown at salinities as low as 12 psu without negatively affecting growth and production.

Abstract:

An in-house hydrodynamic and salinity transport model was used to test the performance of several salinity control designs in Calcasieu Lake, Louisiana. The 256 sq.km shallow water lake is located in southwest Louisiana, with a 5 mile waterway (Calcasieu Pass) connecting to the Gulf. The salt water in the lake comes from the Gulf due to daily high tide and due to storm surges. In the south west part of the lake, called West Cove, has unique flow circulations and has relatively high salinity concentration comparing to the other part of the lake. A deep Calcasieu Ship Channel is the eastern border of West Cove. The surrounding wetlands of West Cove are disappearing due to the salt water intrusion. The vegetation is dying due to the high salinity concentration, and the soils are eroded quickly without the surface vegetation. The design goal is to reduce the salinity concentration in West Cove without reducing too much flow. The proposed designs include installing a levee and flow and salinity control stations at the eastern border of West Cove separating the water body with Calcasieu Ship Channel. The optimal length and location of the levee and the flow control structure are the objectives of the research. The in-house code was used to simulate the hydrodynamics and salinity transport with the different designs. The results were used to show the effectiveness of the designs on reducing the average salinity concentration in the area and maintaining reasonable flow speed in and out of the area. In the implementation of the designs, the flow and salinity control stations were also included in the simulation. The main function of the stations is to block the salt water from the Gulf during high tide, and direct the fresh water from the north into the area during low tide. This action can keep maintain a single direction fresh water flow from north to south in order to keep salt water out of the system.
