Drought stress reduces seed crop yields in part by causing reproductive sterility associated with increased endogenous ABA. Application of the film antitranspirant, di-1-p-menthene, during reproductive-stage drought has been shown to ameliorate yield loss wheat but physiological processes involved are not understood. Using rain shelters simulate Mediterranean-type terminal drought, we studied p...

Drought is the main constraint to maize production in Mediterranean area. This first report of breeding temperate populations from Algerian desert. The objective this study was evaluate response selection for reduced anthesis-silking interval (ASI) under drought and control conditions. Three cycles ASI were carried out four conditions, program evaluated both Selection more efficient than partic...

Drought stress is a major abiotic constraint limiting crop production world wide. In current study, we investigated the adverse effects of drought stress on growth, yield and endogenous phytohormones of soybean. Polyethylene glycol (PEG) solutions of elevated strength (8% & 16%) were used for drought stress induction. Drought stress period span for two weeks each at pre and post flowering growt...

Experiments were carried out to investigate the physiological (dry weight of root, stem, peg, flowers plant, fruits sets percent, pod yield (kg plot), 100-kernel weight, days to flowering and maturity) and biochemical (endogenous proline level) traits of groundnut cultivar Swat Phalli-96 under drought stress. The result showed that drought stress significantly (p < 0.05) reduced dry weight of r...

Drought stress is one of the major abiotic stresses in agriculture worldwide. This study was carried out to investigate the effect of drought stress on chlorophyll content, photosynthesis and transpiration, stomatal conductance and yield characteristics in two varieties of tartary buckwheat (Fagopyrum tataricum). A pot experiment with three irrigation regimes was carried out in a split-plot blo...

in order to evaluate the best drought resistance indices in sugar beetgenotypes, an experiment was conducted in 2002 using a split- plot design within randomized complete block design with three replications at the research farm, shiraz-zarghan. the main plots consisted of three irrigated regimes: non stress, 75% (mid stress) and 50% (intense stress) non stress and the ten genotypes as the sub ...

Scarcity of water for irrigation is an alarming issue limiting crop production worldwide and is becoming increasingly severe with the passage of time in Pakistan. Rice production in Pakistan is thus, being adversely hampered by the shortage of water. The study was therefore, contemplated to determine the effect of drought stress on some physiological and agronomic parameters of three rice culti...

Identification and evaluation of drought tolerant germplasm is the primary step for sorghum (Sorghum bicolor L. Moench) breeding and utilization under drought conditions. The objective of this study was to use a grey relational analysis to investigate the role of feasible physiological parameters in evaluating drought tolerance in sorghum. Four sorghum varieties were cultivated in pots with two...

Drought escape (DE) is a classical adaptive mechanism which involves rapid plant development to enable the completion of the full life-cycle prior to a coming drought event. This strategy is widely used in populations of native plants, and is also applicable to cereal crops such as wheat. Early flowering time and a shorter vegetative phase can be very important for wheat production in condition...
