Leaf exchange is an abrupt phenological event that drastically modifies the morphology and physiology of the aerial portion of the plant. We examined if water and osmolyte differences between old leaves and new organs trigger leaf exchange, and whether the differences are closely linked to the resource resorption process in senescing leaves. We monitored concentrations of osmolyte, water, non-s...

evaluating of some physiological indices for recognizing water deficit effects, selecting water deficit tolerant oilseed rape genotypes and also evaluation of drought effects on seed and oil yields and its components were the goals of this study. the experiment was conducted as factorial based on a randomized complete blocks design with three replications in east azarbaijan research center for ...

We investigated the applicability of the Implicit Association Test (IAT) to children, 100 three to seven year-olds attempting a fully non-verbal adaptation of the IAT involving insect and flower stimuli. Ninety-four achieved 75% accuracy, and these participants attempted a second IAT, incorporating fat and thin female body shapes. Implicit attitude effects in both tests occurred throughout the ...

in order to study of the effect of priming and salinity on physiological and chemical characteristics of wheat(triticum aestivum l.), an experiment was carried out at the experimental farm of shiraz university. results showedthat primed plants significantly reduced its gas exchanges by accelerating senescence under a series of salt stress,which became more serious along with the increasing of s...

this research was carried on in order to investigate the response of wheat cultivars to salinity tension as factorial experiment and in complete randomized block design in four replications in islamic azad university shoushtar branch. in this experiment the response of nine wheat cultivars including chamran, karchia66, mahoti, roshan, alvand, kavir, ghods, atrak and tjan at vegetative growth st...

Plant species distributions are determined by the response of populations to regional climates; however, little is known about how alien plants that arrive in central Europe from climatically warmer regions cope with the temperature conditions at the early stage of population development. Ambrosia artemisiifolia (common ragweed) is an invasive annual plant causing considerable health and econom...

water is the most limiting factor in irrigated agriculture, mainly in mediterranean environments, as in the case of southwest spain. in this area, almond is one of the most valuable crops due to its high drought tolerance. this work examines the crop coefficients (kc) based on four drainage lysimeters installed in an experimental young almond orchard. complementary, two deficit-irrigation treat...
