breeding medics species to drought and salinity tolerant  can play an important role in herb production and pasture rehabilitation. with the aim of study of the performance of annual burr medics under drought and salinity stresses, a pot study was conducted with factorial arrangement of treatments in a randomized complete block design in shiraz university. sown seeds were two types (threshed an...

for determination of water stress effects in different growth stages of sugar beet and optimum water usage on quantity and quality of sugar beet, this study was performed using randomized complete blocks design in factorial experiment with 12 treatments and 4 replications from 1999 to 2001 in agricultural research center of hamadan. the first factor was non-irrigation in 3 stages of growth (s1-...

1 We hypothesized that severe drought affects the structure of tropical forests by favouring seedlings of some species or groups at the expense of others. To test this hypothesis, we irrigated naturally occurring woody seedlings during an El Niño-related drought in seasonal moist tropical forest on Barro Colorado Island, Panama. We predicted that irrigated plots would retain greater species ric...

Drought stress in plants, the change (increase or decrease) in the production of plant proteins. Proteomics in recent years one of the most powerful tools that help us to study the changes in protein In order to investigate the proteome of wheat leaves in response to terminal drought, two genotypes susceptible and resistant wheat genotypes were evaluated under irrigated (non-stress) and rain-fe...

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 ...

In wheat, stem water soluble carbohydrates (WSC), composed mainly of fructans, are the major carbon sources for grain filling during periods of decreasing photosynthesis or under drought stress after anthesis. Here, in a field drought experiment, WSC levels and associated enzyme activities were followed in different stem segments (peduncle, penultimate internode, lower parts of stem, and sheath...
