Opportunities to directly study infrequent forest disturbance events often lead to valuable information about vegetation dynamics. In mesic temperate forests of North America, stand-replacing crown fire occurs infrequently, with a return interval of 2000-3000 years. Rare chance events, however, may have profound impacts on the developmental trajectories of forest ecosystems. For example, it has...

Cotton germplasm was analyzed to investigate its potential for developing water stress tolerance in varieties in the future. Four tolerant (NIAB-78, CIM-482, BH-121, and VH-142) and four susceptible (CIM-446, FH-1000, FH-900, and FH-901) lines were identified of 50 accessions based on their seedling root length. A complete set of diallel crosses among eight selected genotypes was subjected to g...

Micronutriens deficiency is prevalent in case of drought stress conditions, so complementary boron and zinc nutrition are important for crops to overcome drought stress. This study evaluated the effect of zinc and boron foliar application on physiological traits of sesame under different irrigation levels. The experiment was conducted as a split plot in a randomized complete block design with t...

Lipid transfer proteins (LTPs) are a class of cysteine-rich soluble proteins having small molecular weights. LTPs participate in flower and seed development, cuticular wax deposition, also play important roles in pathogen and abiotic stress responses. A non-specific LTP gene (SiLTP) was isolated from a foxtail millet (Setaria italica) suppression subtractive hybridization library enriched for d...

The general theme of this paper is that drought, though an agro-climatic phenomenon, has phenomenon far reaching socio-economic consequences. adverse impact drought on the poorer sections devastating, while richer classes may actually benefit from it. There emerge a emerge, new middle class consisting peasantry, rich families and traders in countryside section engaged urban based trading, indus...

in order to evaluate the effects of drought stress and plant density on yield, yield components and morphological characters of pinto bean (phaseolus vulgaris l.) c.o.s16 cultivar, a field experiment was conducted in split plot arrangement based on a randomized complete block design with three replications in research field of yasouj university during 2010. experimental treatments were pinto be...
