Abstract:

For this piece, Ross Chambers proposes a reflection on the academic ‘discipline’ – on writing, literary theory, history and hauntings, and on the time spent, lost, and bound up both with writing books and falling in love with books long dreamt of and planned out, but which fall by the wayside in the course of a life spent thinking, reading, and writing (e.g., studies of Berlioz and Gautier, on the audience as an ex-timate included/excluded third-party in theatre, or a ‘Big Book on Baudelaire’). In this poignant, powerful piece on personal and intellectual œuvres that are, in some sense, always bound to remain incomplete (or désœuvrées), Chambers takes us through, as idle fellow flâneurs, a kind of auto-bio-bibliography: that is, a texturing/textualization of the self as thinker and writer who has dedicated the last fifty years to interrogating the radically disruptive potential of that strange institution he calls loiterature.

Abstract:

Cette étude se veut une analyse de la pièce Tu faisais comme un appel, signée Marthe Mercure, selon la théorie de récit post-traumatique élaborée par Cathy Carruth, Mieke Bal et Ross Chambers. L’auteur propose que, tout comme le docudrame qui se veut « vrai » tout en étant une création dramatique, la pièce de Mercure se situe à la frontière entre la fiction et la non-fiction. Il s’agit donc d’un événement théâtral qui met sur scène la « vraie » histoire de quatre orphelines de Duplessis et qui engage le public tant sur le plan théâtral que sur le plan social et politique.

Abstract:

Open top chambers (OTCs) were established in the northern part of the James Ross Island, Antarctic Peninsula, as a part of long-term program in January 2007. They were installed in two typical locations differing in vegetation cover. First group was set in a seashore ecosystem dominated by moss carpet supplemented with few lichen species. The other group was located on the top of a volcanic mesa (350 m a.s.l.) with irregular cover of lichens Usnea antarctica and Umbilicaria decussata. Temperature regimes inside and outside OTCs were continuously measured and related to year-round reference meteorological data. For majority of OTC installations, temperature increase caused by OTC was apparent in the period of September-March. Detailed analysis of chamber effect on the increase in air, surface, vegetation, and ground temperatures was done for late austral summer seasons of 2007 and 2008, and 10 years later, the seasons of 2017 and 2018. The OTC-induced temperature increase was more pronounced for mesa than seashore plot. For both locations, OTC-induced increase in temperature was highest for warm days with full sunshine and limited wind speed. On stormy days with overcast sky and high wind speed, the shift in temperature was smaller. Consequences of a long-term manipulation of Antarctic terrestrial ecosystems by OTCs for moss and lichen ecophysiology are discussed.

Abstract:

Hypobaric or low-pressure storage (LPS) is a technology that has been reported to have significant potential to preserve fresh produce quality. However, excessive moisture loss has often been erroneously reported to limit the utility of LPS. We report on hypobaric (1.6 to 2.0 kPa) storage of representative bulky and leafy fruits and vegetables {strawberry (Fragaria ×ananassa Duchesne ex Rozier) fruit, carrot [Daucus carota subsp. sativus (Hoffm.) Arcang.] roots, spinach (Spinacia oleracea L.) leaves, and rose (Rosa ×hybrida ‘Attaché Pink’) flowers} using a laboratory-scale LPS and provide data on the regulation of humidity and temperature and describe effects on moisture loss and quality. The LPS achieved near saturation (>99.5%) of water without condensation on the chamber sidewalls. This required tight regulation of the chamber wall temperature (2.2 °C ± 0.15 °C) and careful control of the flux of air into the chamber. The rate of moisture loss was unaffected by the pressure of the storage atmosphere; however, it was affected by commodity, being lower for strawberry than for carrot or spinach, and averaging 0.08%, 0.40%, and 0.35% per day, respectively (average of normal and low pressure combined). Moisture loss of long-stemmed rose in LPS averaged 0.071% per day over an 8-week storage period. Although moisture loss was low, the LPS environment appeared to enhance water loss from deeper within plant tissues than storage at atmospheric pressure and, in roses, resulted in bent neck 2 or 3 days after removal from storage after 3 weeks. For this reason, LPS did not benefit storability of cut ‘Attaché Pink’ roses compared with high-humidity chambers maintained at atmospheric pressure.

Full text

Abstract:

Prompted by the prior work of critics like Ross Chambers and sociologist Pierre Bourdieu, this article pursues the possibility that there would be a way of reading Madame Bovary that is not just about learning to be a sophisticated and refined enough reader of Gustave Flaubert to appreciate all that he managed to achieve in that novel. Rather, while sophistication and refinement may constitute a typical first step in becoming a reader of Flaubert’s novel, the novel also, from a different perspective, offers a critical experience of the symbolic violence of a cultural universe structured by hierarchies of sophistication, potentially leaving you wondering what your fought-for sophistication is really worth. While pursuing this possibility, I examine how Madame Bovary continually figures acts of reading such as the one it is offering its readers, how a sensibility to free indirect style can be considered an index of sophistication, and how Flaubert uses figural language and certain prosodic effects to create collisions of registers of diction that destabilize any secure sense of linguistic sophistication.

Abstract:

AbstractCenozoic magmatic rocks related to the West Antarctic Rift System crop out right across Antarctica, in Victoria Land, Marie Byrd Land and into Ellsworth Land. Northern Victoria Land, located at the northwestern tip of the western rift shoulder, is unique in hosting the longest record of the rift-related igneous activity: plutonic rocks and cogenetic dyke swarms cover the time span fromc.50 to 20 Ma, and volcanic rocks are recorded from 15 Ma to the present. The origin of the entire igneous suite is debated; nevertheless, the combination of geochemical and isotopic data with the regional tectonic history supports a model with no role for a mantle plume. Amagmatic extension during the Cretaceous generated an autometasomatized mantle source that, during Eocene–present activity, produced magma by small degrees of melting induced by the transtensional activity of translithospheric fault systems. The emplacement of Eocene–Oligocene plutons and dyke swarms was focused along these fault systems. Conversely, the location of the mid-Miocene–present volcanoes is governed by lithospheric necking along the Ross Sea coast for the largest volcanic edifices; while inland, smaller central volcanoes and scoria cones are related to the establishment of magma chambers in thicker crust.

Abstract:

The American Elections This Year Overturned conventional expectations. In March 1991 President Bush — leader of the free world during the fall of the Berlin wall and winner of the Gulf war — seemed invincible. With the troops home in victory parades, Bush's approval rating stood at 88 per cent in Gallup polls. Few thought he could lose against Governor Clinton, dogged by questions about the draft and marital fidelity, perceived as a second-rank Democratic contender from a small southern state. Yet President Bush won 37.7 per cent, the lowest share of the popular vote of any incumbent president since William Taft in 1912. Against most predictions, 19 per cent of the vote went to Ross Perot, the best result for a third party candidate since Teddy Roosevelt. Governor Clinton enjoyed a comfortable victory, with 43.2 per cent of the popular vote and 370 electoral college votes in 32 states. The result for Clinton was not a landslide, indeed his share of the popular vote was similar to Mondale's in 1984 and Carter's in 1980, and less than Dukakis's in 1988. But questions about a popular mandate are academic: Democrats now control both ends of Pennsylvania Avenue, and almost two-thirds of governorships and state legislative chambers.

Full text

Abstract:

To assess the effects of summer-like [high-temperature long-day (HTLD)] vs. winter-like [low-temperature short-day (LTSD)] growing conditions on production quality and postproduction longevity of potted miniature roses, plants of Rosa L. `Meirutral' and `Meijikatar' were grown in growth chambers using a short-cycle production schedule (potted liners grown until root establishment, pinched, and flowered). Plants grown under the HTLD environment [30C day/21C night plus 725 μmol·m–2·s–1 photosynthetic photon flux (PPF) for 14 hours per day] had more flowering shoots than those grown under the LTSD environment (21C day/16C night plus 725 μmol·m–2·s–1 PPF for 10 hours per day). The difference is attributable to fewer blind shoots (shoots with aborted growing terminals) under HTLD, because plants in both environments had the same total number of shoots at flowering. Plants in the HTLD chamber also flowered faster, were shorter, and had smaller and lighter-colored flowers than plants in the LTSD chamber. In addition, plants under HTLD exhibited greater poststorage floral longevity and whole-plant shelf life than plants grown under LTSD conditions, regardless of cultivar, simulated shipping (storage) treatment (4 days at 16C), or stage of floral development at harvest. These results suggest benefits from summer production of potted miniature rose plants and the possibility of using a higher-temperature forcing regimen than is normally recommended for winter production.

Full text

Abstract:

Appropriate cold stimulation can improve immune function and stress tolerance in broilers. In order to investigate the effect of intermittent mild cold stimulation on the intestinal immunity of broilers, 240 healthy one-day-old Ross 308 chickens were randomly divided into three groups: the control group (CC) housed in climatic chambers under usual rearing ambient temperature with a gradual 3.5 °C decrease per week; group II (C3) and group III (C6) to which cold stimulation at 3 °C below the temperature used in CC was applied every two days for 3 and 6 h, respectively, from day 15 to 35, and at the same temperature used in CC from day 35 to 43. The mRNA expression levels of immunoglobulins (IgA and IgG), cytokines (IL2, IL6, IL8, IL17, and IFNγ), and Toll-like receptors (TLR2, TLR4, TLR5, TLR7, and TLR21) were investigated in duodenum, jejunum, and ileum tissue samples on days 22, 29, 35, and 43. From day 15 to 35, mRNA expression of IL2 and IFNγ was increased in the intestine of broilers. After one week of cold stimulation on day 43, mRNA levels of immunoglobulins, cytokines, and Toll-like receptors (TLRs) stabilized. Collectively, the findings indicate that cold stimulation at 3 °C below the usual rearing temperature had a positive impact on intestinal immunity of broilers.

Full text

Abstract:

A study was conducted to determine the predictability of energy balance and energy efficiency by using dietary chemical composition. Closed-circuit indirect calorimetry was used to determine the apparent metabolisable energy (AME), respiratory quotient, heat increment (HI), net energy (NE) and ratio of NE to AME (NE : AME) of a series of diets with varying levels of chemical constituents. Diets were analysed for DM, gross energy, protein, fat, ash, crude fibre, acid detergent fibre, neutral detergent fibre, starch, sugars (mono- and disaccharides), and soluble, insoluble and total non-starch polysaccharides. Ross 308 male broilers were acclimatised to chambers and diets for 3 days and 12 days, respectively, before O2 consumption and CO2 expiration were measured gravimetrically. Gross energy of feed consumed and excreta voided were measured and AME was calculated. Heat production was calculated using the Brouwer equation based on O2 and CO2. After taking fasting heat production into account by using a value of 450 kJ/BW0.70, HI was determined. NE was calculated as AME minus HI. The results showed high predictability of AME (R2 = 0.89) and NE (R2 = 0.85) by using chemical components. HI was less predictable (R2 = 0.25). Efficiency of energy utilisation (NE : AME) was predicted (R2 = 0.40). Closed-circuit calorimetry was found to be useful for evaluating the contribution of the chemical components of feed ingredients to the efficiency of energy utilisation in broilers. These results may be used to reduce energy costs in broiler feed formulation.

Full text

Abstract:

Growth predictions derived from data collected in controlled-environment chambers would be expected to differ from growth responses observed in variable greenhouse conditions. ROSESIM was developed as a dynamic plant growth model based on `Royalty' rose (Rosa hybrida L.) response to 15 unique treatment combinations of photosynthetic photon flux (PPF), day temperature (DT), and night temperature (NT) under constant growth chamber conditions. Regression coefficients for growth equations are read from an external ASCII file, thus permitting coefficients up to a full quadratic model form. Calibration coefficients (CC) were added to ROSESIM to enable predictions to be altered proportionally to permit improved prediction of specific growth characteristics. Numerator and denominator values for CC are adjustable for the first 10 days (initial) growth equations, subsequent growth until anthesis equations, and for the prediction of anthesis. Validation studies were used to set CC values; this enables the model based on growth in controlled environment chambers to be systematically calibrated on site to fit actual growth measured at a specific greenhouse location.

Abstract:

AbstractThe cynipid Diplolepis triforma Shorthouse and Ritchie induces a fusiform, multi chambered stem gall from leaf buds on Rosa acicularis Lindl. in central and western Canada. Galls at all stages of development were fixed and sectioned using botanical histological techniques to illustrate, for the first time, the unique host-modifying abilities of gall-inducing cynipids that distinguish them from other phytophagous insects. Key events in gall ontogeny, whereby D. triforma gains control and redirects the development of attacked host tissues to provide larvae with shelter and food, include proliferation of cytoplasmically dense parenchymatous cells within the strands of the procambium at the point of egg contact, appearance of nutritive cells when larvae first begin to feed, formation of new xylem and phloem extending from un affected vascular bundles to the larval chambers, formation of several layers of nutritive cells during the period of larval feeding, and formation of sclerenchyma cells around each larval chamber. The role of these tissues in galler biology is explained.

Abstract:

Abstract Purpose: Despite widespread studying of the polarity effect of Roos parallel plate ion chamber in electron beams as mentioned in several protocols, no investigations have up till now studied this effect in photon beams in the build-up region. It is important to examine its polarity effect in the build-up region for photon beams, so this is the first work that focuses in to evaluate the polarity effect of the Roos chamber in the surface and build-up region and comparing its effect with other chambers. Methods: In this study, the Roos chamber was irradiated by a Theratron 780E 60Co beam to a known polarity effect. The Polarity effects of 5×5 up to 35×35 cm2 field sizes at positive and negative polarizing voltages were measured in the build-up region from surface to 0.7 cm in a solid water phantom. Results: The polarity ratios (PRs) were obtained at 1.020 ± 0.00 and 1.015 ± 0.00 for field sizes 5 × 5 up to 35 × 35 cm2, respectively. For the same fields, the percentage of polarity effects (%PEs) was obtained at 1.99% ± 0.00% and 1.47% ± 0.02%, respectively. The results found that the %PEs decrease with increased field sizes and depths. Moreover, the %PEs exhibited a decrease with an increased percentage surface dose (%SD). The uncertainty of %PE was estimated as 0.01% for all measurements in this study. Conclusions: As a result, the average %PE of the Roos chamber described here is equal to 0.756% ± 0.013% for all depths and field sizes for the 60Co γ-ray beam. It has introduced a less percentage of polarity effect than other chambers.

Abstract:

Abstract The relationship between Botrytis cinerea inoculum concentration and Botrytis blight on Rosa hybrida flowers from production greenhouses was monitored in the fall of 1985 and 1986 and winter of 1986 and 1987 under laboratory conditions. ‘Golden Wave’ rose flowers were inoculated with 0 to 104 conidia per milliliter and stored in incubation chambers at ≥95% RH and 21°C. Disease severity was quantified by the number of lesions per flower 48 hr after inoculation. The relationship between inoculum concentration and disease severity was linear; the coefficient of determination ranged from 0.87 to 0.99. The slope of the inoculum concentration–disease severity relationship was used to quantify susceptibility, which ranged from 0.006 to 0.035. Slopes were significantly greater with roses produced in December, January, and February (0.018 to 0.035) than those produced in October or November (0.006 to 0.013). Susceptibility of the flowers to B. cinerea was correlated linearly (r = 0.98) and inversely to the overall mean vapor pressure deficit from 0800 to 1900 hr for the 5-week growth period before harvest.

Abstract:

AbstractWe tested the enemy hypothesis for gall morphology on a model system comprising twoDiplolepisrose gall wasp species and their associated parasitoids. The enemy hypothesis predicts both that gall traits will influence parasitoid attack rates within species, and that galls with contrasting morphologies will support different parasitoid communities. This hypothesis is supported by studies at both intraspecific and broader taxonomic levels (i.e. between genera), but patterns remain to be explored in closely related species. Our aims were to explore the relationships between aspects of gall morphology (number of larval chambers, overall gall size and thickness of the gall wall) in each ofDiplolepis mayriandD. rosae, and to explore correlations between these traits and both the presence/absence (=incidence) and attack rates imposed by parasitoids. We found in both galls that chamber number is positively correlated with gall size. In galls ofD. mayri, parasitoid incidence was negatively correlated with thickness of the wall of the larval chamber, but there was no significant correlation between parasitoid attack rates and overall gall size. InD. rosaegalls, parasitoid incidence was positively correlated with chamber wall thickness, but parasitoid attack rates were negatively correlated with gall size, suggesting that selection may favour the induction of galls containing more larval chambers. These results confirm that gall extended phenotypes can significantly influence enemy attack rates, consistent with the ‘enemy hypothesis’. Further, differences in gall morphology between the twoDiplolepisspecies may underlie differences in their associated parasitoid communities – further research is required to test this hypothesis.

Abstract:

Absorbed dose to water determination in the clinical practice introduces several perturbations factors in ionization chamber dosimetry. Displacement perturbation is one of them, which can be corrected by introducing the chamber-specific quality correction factor (kQ) or by introducing the concept of effective point of measurement (EPOM). The EPOM is the point in the chamber at which the measured dose would be the same as the measuring depth in absence of chamber. The aim of this study was to measure the displacement effect at cylindrical ionization chambers in 6 and 10 MV flat and true photon beams. The percentage of depth doses (PDDs) were considered for determining the shift of EPOM with respect to the well established Roos chamber. The displacement effect obtained a range of 0.25 to 0.57 times r (chamber radius) both in flat and true beams, which disagreed with the TRS-398 protocol recommended constant value of 0.6r.Journal of Bangladesh Academy of Sciences, Vol. 41, No. 2, 227-235, 2017

Abstract:

Rooted liners of Rosa cvs. Meijikatar and Meirutral were potted into 11 cm pots and placed into growth chambers. One chamber provided 14 hours of light with 30C/21C (day/night) air temperature (HTLD) and another chamber provided 8 hours of light with 21C/17C (day/night) air temperature (LTSD). PPF was 725 μmoles m-2 s-1 in both chambers. When plants were established, they were pinched and forced to flower. Simulated shipping for 4 days at 16C in darkness resulted in a shorter shelf-life when placed in an interior environment at 21C with a continuous PPF of 30 μmoles m-2 s-1 and compared to non-shipped plants. In addition, LTSD grown plants exhibited a shorter shelf-life than HTLD grown plants. When Meirutral plants were sprayed to runoff 24 hours prior to shipping, 2 mmolar (aminooxy)acetic acid (AOA) increased the shelf-life to the same length as the non-shipped plants and 2 mmolar silver thiosulphate (STS) increased the shelf-life to longer than the non-shipped plants. However, AOA did not increase shelf-life over that of shipped plants for Meijikatar whereas STS increased the shelf-life to that of the non-shipped plants.

Abstract:

The growth of Rosa × hybrida and Exacum affine under different spectral filters was evaluated. Three filters that altered light quality were developed. One, a red textile dye, filtered out much of the blue/green portion of the light spectrum but did not change far-red to red (FR/R) light ratio. Another, a blue textile dye, raised FR/R by filtering out a portion of red light. The third, a salt (copper sulfate) lowered FR/R by filtering out a greater portion of far-red than red light. Two controls were used that did not alter light quality. The filters were installed in specally built growth chambers. Photosynthetic Photon Flux Density (PPFD) was adjusted to equal values in each chamber. Plants of both species were significantly shorter and had higher leaf chlorophyll, when grown under the low FR/R filter.

Abstract:

Roses are a high-value niche crop in the higher altitudes of northeastern Brazil. From July of 2007 and throughout 2008, severe stem rot and wilting of rose seedlings were observed in commercial fields in the São Benedito District, Ceará State, Brazil. Although economic losses due to the disease are unknown, it poses a threat to the growing rose industry in that region. Symptoms included leaf yellowing and abscission followed by plant collapse. Symptoms appeared earlier when grafted seedlings were produced during periods of high relative humidity (80 to 98%) and warm temperatures (20 to 31°C). In the laboratory, symptomatic seedlings were rinsed with distilled water, surface sterilized with 0.5% NaOCl, and incubated on PDA at 26 ± 2°C. Fusarium oxysporum was consistently isolated from infected scions and rootstocks. Identification of F. oxysporum was based on colony and conidia morphology obtained from single-spore colonies. Five 4-week-old rose (‘Carola’) seedlings were inoculated with a culture of fungus by spraying the needle-wounded scion with a spore suspension (1 × 105 CFU/ml). The spore suspension was obtained from a 1-week-old PDA culture incubated at 26 ± 2°C. Control seedlings were sprayed with sterile water. Inoculated seedlings were incubated for the first 48 h in a saturated humidity chamber. After 20 days at room temperature, the scion tissue of inoculated seedlings turned necrotic. Two symptomatic seedlings were placed in a saturated humidity chamber for 24 h to determine if fungal sporulation could be observed on the surface of the tissue. After 5 to 7 days, a white mycelium was observed over the necrotic tissue. Seedlings sprayed with sterile water remained symptomless. F. oxysporum was reisolated from symptomatic tissue. An isolate of F. oxyporum (No. 1484) was deposited in the Mycology Collection of Lavras (Minas Gerais State, Brazil). To our knowledge, this is the first report of F. oxysporum causing a disease on rose seedlings in Brazil.

Abstract:

The yellow rose aphid, Acythrosiphon porosum (Sanderson), is a cosmopolitan pest of roses and strawberries. Acythrosiphon porosum is one of only a few arthropod pests of roses occurring in northern Florida and southern Georgia. Hybrid roses are widely planted around the city of Thomasville, GA, which is known as the Rose City. Three ‘Grandiflora’ rose cultivars ‘Queen Elizabeth’, ‘Roundelay’ and ‘Spartan’ were used to determine cultivar and location effects on A. porosum seasonal abundance and natural enemies. Developmental rate, longevity and nymph production of A. porosum were also investigated at 4 temperatures, 10.0, 15.5, 21.1, and 26.7°C, in environmental chambers using cut leaf discs of ‘Queen Elizabeth’ on agar plates. Acythrosiphon porosum occurred throughout much of the year except for the coldest winter and warmest summer months and reached highest populations during the cooler weather of spring and fall. Cultivar differences were statistically significant at all locations where ‘Queen Elizabeth’ averaged higher aphids per leaf than ‘Roundelay’, which averaged higher aphids than ‘Spartan’. Aphid numbers did not significantly differ in comparisons of leaves sampled from the bottom, middle or top third of the plant's canopy height. Developmental rate calculated as the time from nymph to nymph was most rapid (x̄ = 10.3 d) at 21.1 °C, but no aphid development was observed at 26.7°C. Total egg production was highest (x̄ = 27.5 nymphs per aphid) at 10.0°C as was longevity of 60.1 d. Highest nymph production (1.5 per d) was observed at 21.1 °C. Many generalist predators and two parasitoid species were found in low numbers attacking A. porosum: Syrphophagous aphidovorus (Mayr) (Hymenoptera: Encyrticidae) and Ephedius sp. (Hymenoptera: Aphidiidae).

Abstract:

Abstract Monoclonal antibodies (MAbs) are a well-established treatment approach in oncology and other diseases. Nevertheless, many multipass membrane proteins are largely inaccessible as antibody targets due to their poor expression, membrane-dependent structure, small extracellular regions, and high sequence conservation between humans and rodents. Integral Molecular’s MPS Antibody Discovery platform specifically addresses each of these challenges. A key enabling feature of MPS is the use of chickens as an evolutionarily divergent host species for immunization, allowing a more robust immune response for targets that are highly conserved in mammals. We will present on antibodies isolated against challenging membrane protein targets in oncology including Claudin 18.2 (CLDN18.2).CLDN18.2 is a transmembrane adhesion protein undetectable in most adult healthy tissues but highly expressed in gastric, pancreatic, esophageal, and lung cancers. Antibody discovery efforts against this validated target are challenging due to the abundant expression of the splice isoform CLDN18.1 differing by only 8 amino acids in the extracellular domain. As part of the MPS platform, we used virus-like particles (Lipoparticles) to immunize chickens with a high concentration of native CLDN18.2 protein and obtain high-titer immune responses. This enabled us to generate and isolate a large and diverse collection of MAbs (48 unique clones) and select candidates for optimization. We present a panel of three highly specific, humanized CLDN18.2 MAbs with picomolar affinities that are superior to the clinical-stage benchmark. We will show in-depth profiling data for the MAb panel that were used for lead selection and de-risking clinical development. These data include biosensor binding kinetics, amino-acid resolution epitope mapping, and specificity testing against the Membrane Proteome Array (MPA) consisting of 6,000 membrane proteins. This panel of preclinical antibodies are being developed for therapeutic use in various formats, including bispecifics, antibody-drug conjugates, and CAR-T applications.

Abstract:

The decline in sales of garden roses can, in part, be attributed to the lack of well-adapted cultivars. Successful selection for any trait requires an accurate phenotyping protocol. Apart from field screening, a protocol for phenotyping high-temperature tolerance in garden roses is yet to be established. An experiment was conducted to determine the stage of development when flowers were most sensitive to high-temperature stress. Liners of Rosa L. ‘Belinda’s Dream (BD) and the Knock Out® rose ‘RADrazz’ (KO) were planted in a soilless medium and grown in a greenhouse. Established plants were pruned retaining several nodes with leaves on two main shoots and treatments started. The experiment was conducted in growth chambers held at either 24/17 °C (control) or 36/28 °C (stress) day/night temperatures. Six time and duration temperature treatments included 8 weeks of continuous control conditions, 8 weeks of continuous stress conditions, and four sequential 2-week high-temperature shock treatments. Continuously stressed plants flowered in the least amount of days but did not differ from the continuous control-treated plants based on nonlinear thermal unit accumulation until flowering. Both cultivars had a 70% reduction in flower dry weight under continuous stress conditions. Flowers were most sensitive to high-temperature stress at the visible bud stage, which corresponds to Weeks 5 to 6 and Weeks 7 to 8 for BD and Weeks 3 to 4 and Weeks 5 to 6 for KO, respectively. KO was more resistant to flower abscission than BD when treated at the visible bud stage, but no difference in flower dry weight reduction between BD and KO was found. The number of vegetative nodes to the flower was unaffected by treatment and differed between the cultivars.

Abstract:

Diplolepis nodulosa (Beutenmüller) induces small, single-chambered, prosoplasmic galls in stems of Rosa blanda Ait. Gall initiation begins when adult females deposit a single egg into the procambium of R. blanda buds. Pith cells at the distal pole of the egg lyse forming a chamber into which the hatching larva enters. Cells lining the chamber differentiate into nutritive cells, which serve as the larval food. Gall growth is characterized by the proliferation of parenchymatous nutritive cells causing gall enlargement. A separate gall vasculature does not form, but instead, gall tissues are irrigated by the existing stem vasculature. Maturation begins when gall tissues cease proliferating and differentiate into distinct layers concentrically arranged around the larval chamber. The innermost layer is composed of cytoplasmically dense nutritive tissue, followed by parenchymatous nutritive tissue, sclerenchyma, cortex, and epidermis. Parenchymatous nutritive tissue differentiates into nutritive tissue and is consumed by the larva. Galls of D. nodulosa are susceptible to anatomical modification by the phytophagous inquiline Periclistus pirata (Osten Sacken). Galls attacked by P. pirata become enlarged and multichambered, with little resemblance to inducer-inhabited galls. Periclistus pirata kill the larva of D. nodulosa at oviposition and deposit several eggs per host gall. Inquiline-occupied galls may contain the eggs of several females. Nutritive tissue induced by D. nodulosa disintegrates. Growth of attacked galls occurs prior to hatching of P. pirata eggs. At egg hatch, the gall appears as an enlarged hollow sphere and larvae disperse over the chamber surface and feed on parenchymatous tissue. Feeding induces tissue proliferation, which surrounds each larva within its own chamber. As galls mature, cells surrounding each larval chamber lignify forming a sclerenchyma sheath. Cells inside the sclerenchyma sheath differentiate into nutritive cells and are consumed by the inquiline larvae.Key words: Rosa, Cynipidae, gall, developmental morphology, inquiline.
