Drought is the most important factor limiting rice productivity in the rainfed areas of Asia. In this study, 48 pyramiding lines (PLs) and their recurrent parent, IR64, were evaluated over two years for their yield performances and related traits under severe drought stress at the reproductive stage (RS), the vegetative stage (VS) and irrigated control in order to understand the relationship be...

Drought-induced (Di19) proteins played important roles in plant growth, development, and abiotic stress responses. In the present study, a total of seven Di19 genes were identified in soybean. Each soybean Di19 gene showed specific responses to salt, drought, oxidative, and ABA stresses based on expression profiles. With a relatively higher transcript level among Di19 members under four stress ...

Cotton exhibits moderately high vegetative tolerance to water-deficit stress but lint production is restricted by the available rainfed and irrigation capacity. We have described the impact of water-deficit stress on the genetic and metabolic control of fiber quality and production. Here we examine the association of tentative consensus sequences (TCs) derived from various cotton tissues under ...

in order to study of drought tolerance in advanced grain sorghum lines, an experiment was conducted in a split-plot on randomized complete block design with three replications in experimental field of seed and plant improvement institute, karaj, iran during 2009-2010. irrigation regimes were assigned to main plots at three levels including normal irrigation (i1=60mm), moderate stress (i2=120mm)...

The warming Canadian summers have become a major abiotic stress to crops, including pea. In the past decade, attempts were made in understanding of heat effect and genomic mapping for heat-responsive traits field this study, new recombinant inbred line population (PR-24) consisting 39 lines was tested 6 trials 2020 (near normal weather conditions) 2021 (hot/dry conditions). PR-24 phenotyped day...

salinity stress is one of the most important abiotic stresses which threaten plants. in order to study the effect of salinity stress on yield and yield components of sunflower and also genetic analysis of these traits in relation with salt tolerance, a factorial experiment based on a completely randomized design with three replications was conducted. pots were arranged outside the greenhouse in...

Oxidative stress is commonly induced when plants are grown under drought stress conditions.To analyze how salicylic acid (SA) can partly alleviate drought-induced oxidative stress and negative impacts of drought on physiology and growth of Salvia nemorosa plants, we investigated the physiological responses of S. nemorosa to SA application under drought stress. The treatments were composed of Co...

Photosynthesis is the basic process influencing crop productivity. It can be inhibited by drought. Seven sour cherry genotypes were challenged by drought to assess their photosynthetic efficiency in such conditions. All together with relative water content (RWC) as indicator of plant water status, maximum quantum yield of photosystem II (Fv/Fm) and chlorophyll content (Chl a+b) differentiated i...

Environmental stress, especially drought stress, can play an important role in the reduction of the plant growth stage, specifically duringgermination in arid and semi arid regions in Iran.. In order to study the effects of drought stress on germination indices in wheat cultivars, an experiment was conducted in factorial form, using a completely randomized design of four replications. In this e...
