Résumé :
Drought stress frequently occurs in the reproductive stage of wheat, causing significant yield loss. To study the developmental stage dependency of the effect of drought stress on photosynthesis, plants of the drought-tolerant Plainsman V and sensitive Cappelle Desprez winter wheat varieties were grown in phytotron chambers and subjected to water withholding during three phenophases of reproductive development: meiosis, anthesis and early seed development (ESD).Stomatal conductance (gs) and net photosynthesis (Anet) showed similar characteristics. Meiotic-stage drought only decreased the values of Cappelle Desprez significantly. Stressed Plainsman V showed a significantly smaller reduction and better regeneration for these parameters at anthesis. The decreases in gs and Anet were similar in both varieties when drought was applied during ESD. Studies on the intercellular CO2 concentration (Ci) inflexion point implied that metabolic impairment was less typical of stressed Plainsman V than of Cappelle Desprez at meiosis and anthesis. The quantum efficiency of PSII (ΦPSII) did not decline in either genotype during meiotic-stage drought. Stressed Plainsman V showed significantly higher ΦPSII values compared to Cappelle Desprez at anthesis. During ESD, the values for stressed plants of both genotypes decreased to a similar extent.The results indicate that the effect of drought stress on photosynthesis shows developmental stage dependency during the reproductive life cycle of wheat.

Résumé :
AbstractThe assessment of heat and drought tolerance is of primary importance in breeding programmes designed to improve heat and drought tolerance in cereals. Three winter wheat varieties grown in controlled growth chambers were exposed to heat (H) and drought (D) stress singly and in combination (H+D). The combined effects of H and D stress were much more severe than those of individual treatments for both physiological and yield parameters during grain filling. The chlorophyll content, effective quantum yield of PSII, net assimilation rate, transpiration, stomatal conductance and intercellular CO2 concentration were greatly reduced by H, D and their interaction. Grain yield decreased to a greater extent (48.3%) in Plainsman V, averaged over the stress treatments, than in Mv Magma (67.8%) and Fatima 2 (53.7%). The least decline was found in grain number, except in Plainsman V. Mv Magma tolerated heat stress better than Fatima 2. In terms of photosynthetic activity, Plainsman V showed better drought tolerance than Mv Magma. The results showed that changes in physiological properties during stress treatment are not always associated with changes in yield parameters, so a combination of methods may be needed to give a more precise picture of the stress tolerance of wheat varieties.

Résumé :
As a consequence of climate change, the incidence of extreme weather events has increased in Hungary, as elsewhere. Extremely high temperatures are the factor causing the greatest problems for agriculture and crop production. The aim was to determine the heat tolerance of two wheat varieties (Plainsman V. and Mv Magma) by measuring physiological and yield parameters under high temperature conditions (35/20°C day/night) in the phytotron. Heat stress had a substantial influence on the chlorophyll content, antioxidant enzyme activity and yield parameters of the two winter wheat varieties. Heat stress during grain filling led to a significant reduction in the yield, biomass, grain number, harvest index and thousand-kernel weight. Significant differences could be detected between the two varieties, confirming the greater heat sensitivity of Plainsman V. and the better heat tolerance of Mv Magma. The importance of the antioxidant enzyme system was demonstrated in defence against heat stress. The activity of the enzymes glutathione-Stransferase (GSH-S-Tr), ascorbate peroxidase (APx) and catalase (CAT) was enhanced in Plainsman V., and that of GSH-S-Tr and CAT in Mv Magma. The tolerance of the wheat varieties appeared to be correlated with the antioxidant level, though changes in activity were observed for different antioxidant enzymes in the two genotypes tested.

Résumé :
We report a case study of natural variations and correlations of some photosynthetic parameters, green biomass and grain yield in Cappelle Desprez and Plainsman V winter wheat (Triticum aestivumL.) cultivars, which are classified as being drought sensitive and tolerant, respectively. We monitored biomass accumulation from secondary leaves in the vegetative phase and grain yield from flag leaves in the grain filling period. Interestingly, we observed higher biomass production, but lower grain yield stability in the sensitive Cappelle cultivar, as compared to the tolerant Plainsman cv. Higher biomass production in the sensitive variety was correlated with enhanced water-use efficiency. Increased cyclic electron flow around PSI was also observed in the Cappelle cv. under drought stress as shown by light intensity dependence of the ratio of maximal quantum yields of Photosystem I and Photosystem II, as well by the plot of the Photosystem I electron transport rate as a function of Photosystem II electron transport rate. Higher CO2uptake rate in flag leaves of the drought-stressed Plainsman cv. during grain filling period correlates well with its higher grain yield and prolonged transpiration rate through spikes. The increase in drought factor (DFI) and performance (PI) indices calculated from variable chlorophyll fluorescence parameters of secondary leaves also showed correlation with higher biomass in the Cappelle cultivar during the biomass accumulation period. However, during the grain filling period, DFI and PI parameters of the flag leaves were higher in the tolerant Plainsman V cultivar and showed correlation with grain yield stability. Our results suggest that overall biomass and grain yield may respond differentially to drought stress in different wheat cultivars and therefore phenotyping for green biomass cannot be used as a general approach to predict grain yield. We also conclude that photosynthetic efficiency of flag and secondary leaves is correlated with grain yield and green biomass, respectively. In addition, secondary trait associated mechanisms like delayed senescence and higher water-use efficiency also contribute to biomass stability. Our studies further prove that photosynthetic parameters could be used to characterize environmental stress responses.

Résumé :
It is appropriate that Coteau Books should name their new series of Saskatchewan play texts after Florence James, the noted Drama Extension worker of the 1950s. As the biographical note by Rita Deverell suggests, arts policy in Saskatchewan has always been as much about preserving and fostering community at the grassroots level as producing a good artistic product. And the fact that three of the four plays were first produced by Twenty-Fifth Street Theatre, creators of Paper Wheat, indicates the continuing role of the Saskatoon-based theatre in generating and producing original Saskatchewan work among the grassroots. Whatever wider appeal they may have, Roundup, The Plainsman, and Talking Back are plainly directed at Saskatchewan audiences first, and tend to be more celebratory or elegiac than critical and introspective in tone.

Résumé :
Drought-tolerant Plainsman V and drought-sensitive Cappelle Desprez winter wheat genotypes were subjected to heat stress at 34/24°C combined with water withholding during early seed development in order to identify the joint effect of the stressors on embryo and endosperm development. During and after five days of treatment histological observations were made on the developing kernels and compared to yield data. Combined stress shortened the duration of the grain fill. With regard to kernel abortion, thousand-kernel weight and yield per spike, Plainsman V tolerated simultaneous elevated temperature and water withdrawal better than Cappelle Desprez. As a consequence of the stress the accumulation of B-type starch granules was almost completely absent in the endosperms of the sensitive genotype. The results indicate that compared to the drought-sensitive genotype, the tolerant genotype also showed increased tolerance of simultaneous drought and heat stress.

Résumé :
To study the properties of some drought tolerance criteria and agronomic characters in wheat, an eight-parental diallel cross, excluding reciprocals, was grown in a randomized complete block design with three replications under two different water regimes (irrigated and rainfed) for two years in the College of Agriculture at Razi University, Kermanshah, Iran. High broad-sense heritability estimates were observed for harvest index, grain yield, and earliness. Additive gene action was found to be predominant for grain yield, harvest index, relative water content and chlorophyll fluorescence. The results of combining ability analysis revealed that Plainsman was the best general combiner and Plainsman × Kobomugi was the best specific combination for improving drought tolerance. The pooled analysis of variance for combining ability over rainfed conditions reflected that the GCA × environment interaction was not significant for harvest index and chlorophyll fluorescence, and the SCA × environment interaction was non-significant for relative water content and relative water loss, indicating that genes controlling osmoregulation and the other physiological traits mentioned are not affected in these varieties by different rainfed conditions and hence show static stability.

Résumé :
Carlos Fonseca Suárez read Jorge Luis Borges’s short story “El Aleph” as a reflection upon the limits of technological universalism as well as a reconfiguration of modern cosmopolitanism. Carlos Fonseca Suárez then explores the figure of José Arcadio Buendía—founder of Macondo in Cien años de soledad (1967)—who in his obsession with scientific innovation takes Borges’s exploration of technological modernity and the impasses of modern progressivism even further, proposing instead a new dialectical model of universalism. Finally, Carlos Fonseca Suárez concludes by adding a final star to this constellation by exploring how the character of Luca Belladona in Ricardo Piglia’s 2010 novel Blanco nocturno allows for a rereading of this Humboldt’s plainsman scene in the contemporary socioeconomic context, where the relation between the global and the local, center and periphery, becomes intertwined in the elusive informational networks of global capital.
