for evaluation of drought tolerance of sugar beet genotypes by assessment of the drought tolerance indices under mild and severe stresses, furrow irrigated field experiments were carried out at zarghan research station in 2002 and 2004, and at motahari research station (located inkaraj) in 2002, 2003, and 2004. the experimental design was split plot, with a randomized complete block arrangement...

to study of some cryoprotectives in cold tolerant rice genotypes (irctn33 and irctn34) and cold-sensitive rice genotype (hoveize) were selected in previous experiment, fourteen-day rice seedlings exposed fourteen days in 13/15oc (respectively night-day) temperatures as the stress treatment and 22/28oc (night-day) temperature as control treatment in phytotrone. this experiment was conducted in f...

drought stress is the main limiting factor in the arid and semi-arid region of the world. this research was conducted to evaluate drought tolerance in different accessions of sainfoin for yield, morphological and agronomic traits in 2010. twenty one accessions (landraces and varieties) were evaluated in two environments including drought stress and non-stress conditions for four harvests accord...

terminal heat stress is the most widespread heat stress in the world. in order to evaluate the effect of heat stress on yield, yield component, and mopho-phenological traits of barley, 10 barley genotypes including the 2-row genotypes: mahour, khoram, nimrooz, abidar and 6-row genotypes: yousef, rihan 03, izeh, zahak, nosrat, jonoub were tested under normal (optimum sowing date) and heat stress...

the aim of this study was to investigate the effect  of irrigation period on the quality and quantity of yield and some morphological and physiological traits of three multigerm sugar beet genotypes named bp mashhad, bp karaj and 191. the experiment was in a split  plot  based on randomized complete block  design , carried out  at motahari research station of sugar beet seed research institute ...

In order to assess the responses of Hashemi rice genotype and its advanced mutant line under salinity stress of 100 mM Sodium chloride (NaCl) for three and six days the shoot samples were taken for biochemical analysis. This experiment was performed in split plot based on randomized complete block design with three replications. The main factor was factorial combination of saline treatmen...
