An enhanced level of drought tolerance in wheat (Triticum spp.) may be reached through combining agronomic and physiological traits associated with grain yield under conditions. We aimed to explore valuable diversity for the tolerance, existed core collection Iranian spring bread landraces. A number 206 accessions along check cultivar were assessed yield, drought-adaptive traits, estimated crit...
in order to study the effects of post – anthesis heat stress on source of six wheat genotypes (vee/nac, chamran, s79-10, dez, fong and kaveer), two separate field experiments were conducted as delayed as against optimum sowing dates in ahvaz coditions. plants in delayed sowing date experienced heat stress at post-anthesis growth stage. as study of grain yield indicated that the highest and the ...
the responses of yield and yield components of 24 advanced bread wheat genotypes to pre- and post-anthesis drought stress conditions were studied at ardabil agricultural re-search station during the 1997-2000 cropping seasons. results showed that genotypes produced significantly lower spikes no./m2, seeds no./spike and grain yield under pre- than in post-anthesis drought stress conditions. howe...
Tumor antigen-specific T-cell tolerance imposes a significant barrier to the development of effective therapeutic cancer vaccines. Bone marrow-derived antigen-presenting cells (APCs) are critical in the induction of this unresponsive state. Here we show that in vitro treatment of APCs with the tyrosine kinase inhibitor, imatinib mesylate (STI-571), enhances the activation of naive antigen-speci...
This study was conducted to evaluate the drought tolerance of new sugar beet monogerm hybrids. In order to select promising drought tolerant hybrids, two separate field experiments were conducted based on a randomized complete block design (RCBD) with four replications on 25 genotypes of sugar beet (23 new monogerm hybrids and two tolerant and normal controls) at Motahari Research Station, Kama...
Cold stress is one of the most important environmental stresses for rice especially in temperate and high elevation areas. In present study, the effect of different temperatures, as the main plot, including 25 (control), 10 and 5°C on 12 rice cultivars (including Champa Yasouj, Gerde, Lenjan Askari, Kaamfirouz, Kohsar, Shafagh, Domsiya Mamassani, Dular, Gharib, Hasan saraei, Mosa Tarom and 304)...
To study the effect of salt stress on quantitative and qualitative parameters of canola (Brassica napuse. L) cultivars, and determine the possible mechanisms of salt tolerance and the best salt tolerance indices, an experiment was conducted under a rain-shelter at experimental field of university of Kerman in 2004. The experimental design was a complete randomized block (RCOD) with four replica...
Endophytic fungi as the most important soil microorganisms through establishing a symbiotic relationship with various plants play an important role in improving growth and mineral nutrition of their host plants. This research investigates the effect of Piriformospora indica and mycorrhizal fungi treatments on phosphorus efficiency indices and increasing phosphorus deficiency tolerance stress in...

Domestication and artificial selection have reduced the level of genetic variation in barley. Inter-specific hybridization is one of the most valuable ways to restore at least part of the lost variation. This study aimed to investigate genetic diversity and screening barley lines which possessed the desired traits, as well as drought tolerance, within two F3 populations derived by crossing a cu...
