Among different environmental stresses, drought is of great importance that induces a highly negative effect on crop production. In order to evaluate drought tolerance in dryland wheat genotypes, 36 genotypes were studied in a randomized complete block design with three replications under rainfed (drought stress) and supplemental irrigation conditions during 2016–2017 growing season in Research...

Drought stress is one of the most important environmental stresses in reduce of growth and plants production. Determination of resistance mechanisms to environmental stress in plant improvement is very important. In order to , experiment with osmotic potentials of PEG (zero (control), -4, -8 & -12 bar) and alfalfa genotypes was done. The selected alfalfa genotypes namely, Yazdi(tolerant), Niksh...

any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...

In order to evaluate the reaction of foreign genotypes and the indigenous cultivars of barley against drought and study their biochemical traits, eight genotypes with two barley cultivars were surveyed in a randomized complete block design with three replications in two states of sufficient irrigation and non-sufficient irrigation regimes (drought) at the Faculty of Agriculture, Shiraz Universi...

In this research, the possibility of applying selection index of ideal genotype (SIIG) technique for identify tolerate genotypes using the different drought tolerance indices be amended. The experiment was conducted as split plot based on randomized complete block design with three replications at the experimental farm of agricultural research institute and natural resources, Yazd, Iran in 2011...

Extended Abstract Introduction and Objective: Due to the water resources limitation required for agriculture in Iran, providing effective methods to reduce the negative effects of drought on crop yield is one of the important studies to plant breeding. Drought tolerance in crops is very important. By using different cultivars of crops that are able to produce relatively good yield in drought s...

wireless sensor networks (wsns) are one of the most interesting consequences of innovations in different areas of technology including wireless and mobile communications, networking, and sensor design. these networks are considered as a class of wireless networks which are constructed by a set of sensors. a large number of applications have been proposed for wsns. besides having numerous applic...
