drought, high and low tempratures are the most important abiotic stresses in chickpea cultivation. improving plant root characteristics (root length and root volume) is one of the ways to increase drought tolerance in chickpea. mycorrhizal symbiosis increases drought resistance of host plants through different mechanisms. to study the effects of water stress and mycorrhizal fungi inoculation on...

the present study was designed to evaluate the drought tolerance of new sugar beet monogerm hybrids using polyethylene glycol 6000, under in vitro condition. the experiment was carried out as a factorial experiment based on completely randomized design with four replications in sugar beet seed institute, karaj in 2013. 23 new sugar beet monogerm hybrids with two tolerant and normal controls wer...

Water availability is one of the major limiting factors for plant growth. Maize is particularly sensitive to water stress at reproductive stages with a strong impairment of photosynthesis and grain filling. Here, we describe the use of genetic transformation first to assess the role of a candidate gene Asr1-a putative transcription factor-as an explanation for genetically linked drought toleran...

continuous desertification of arable lands mandates use of low quality/ saline water for irrigation, especially in regions experiencing water shortage. using low quality/ saline water for irrigation imposes more stress on plants that are already under stress in these regions. thus, a logical solution will be to find a salt/ drought-tolerant plant species that will survive/sustain under such str...

a major problem of arid and semi-arid regions is environmental stresses like salinity and drought. to study the effect of artichoke germination under different levels of salinity and drought, two separate experiments were performed. the experimental treatments included different salinity levels of nacl (0, 50, 100, 150 mm) and five drought levels by peg (0, 10%, 15%, 20% and 25%) with three rep...

To study the effect of Artichoke germination under different levels of salinity and drought, two separate experiments were performed.

In shallow rainfed rice agro-ecosystems, drought stress can occur at any growth stage and can cause a significant yield reduction. During recent years, some rice varieties possessing tolerance of reproductive-stage drought stress have recently been developed. Tolerance of vegetative-stage drought stress is also required to improve rice productivity in drought-prone regions. In this study, we ev...
