Vigorous discussions and disagreements about the future changes in drought intensity in the U.S. Great Plains have been taking place recently within the literature. These discussions have involved widely varying estimates based on drought indices and model-based projections of the future. To investigate and understand the causes for such a disparity between these previous estimates, the authors...

The objectives of this study were to investigate whether seed biopriming through drought tolerant isolates of Trichoderma harzianum induces drought tolerance in wheat. Physiological and biochemical parameters were also monitored under greenhouse conditions to explore the mechanism underlying plant water stress resilience in response to Trichoderma inoculation.The impact of bioprospecting Tricho...

salinity is a major environmental problem in arid and semi-arid areas. chickpea (cicer arietinum l.), like other legumes is sensitive to salinity. therefore, selection of genotypes to grow on saline areas is important. eleven chickpea genotypes (as sub plots) were grown in the greenhouse conditions on a medium containing different nacl concentrations (8 and 12 dsm-1) and control (hoagland solut...

Drought has emerged as one of the major constraints in banana production. Its effects are pronounced substantially in the tropics and sub-tropics of the world due to climate change. Bananas are quite sensitive to drought; however, genotypes with "B" genome are more tolerant to abiotic stresses than those solely based on "A" genome. In particular, bananas with "ABB" genomes are more tolerant to ...

Drought is a major environmental factor that limits crop growth and productivity. Flue-cured tobacco (Nicotiana tabacum) is one of the most important commercial crops worldwide and its productivity is vulnerable to drought. However, comparative analyses of physiological, biochemical and gene expression changes in flue-cured tobacco varieties differing in drought tolerance under long-term drough...

The potential benefit of drought-tolerant (DT) corn (Zea mays L.) hybrids may depend on drought intensity, duration, crop growth stage (timing), and the array of drought tolerance mechanisms present in selected hybrids. We hypothesized that corn hybrids containing DT traits would produce more consistent yields compared to non-DT hybrids in the presence of drought stress. The objective of this s...

Sci., 20: 155-161 Drought, a serious threat to world agriculture, demands neo-breeding approaches. Tissue culture being a mutagenic process induces somaclonal variations, which can be manipulated for improving dro...

120 Journal of Plant Registrations, Vol 2, No. 2, May 2008 Drought stress reduces dry bean seed yield in most production regions worldwide (White and Singh, 1991). The release of pinto bean (Phaseolus vulgaris L.) germplasm CO46348 (Reg. No. GP-275, PI 651500) will provide plant breeders with drought-tolerant, pinto bean germplasm that takes advantage of a full growing season (95–98 d) and has ...
