water stress effects on winter and spring leaves anatomy were investigated in experiments conducted at the experimental field of sb university of kerman using five wheat cultivars.xylem and phloem elements diameter and mesophyll, bundle sheath and epidermal cells area were measured in transverse sections prepared from middle parts of the leaves. results showed that significant difference exists...

this research was investigated to study relationship among seed yield, seed yield components and morphological traits and their direct and indirect effects on seed yield of 100 safflower genotypes in two water environments (normal and drought stress) at research farm of isfahan university of technology during 2012. seed yield had positive correlation with number of head per plant, seed per head...

abstract many uses of landscape and important roll of ground covers aspect turfgrasses caused extensive of this plant in the cities. this study focuses on shoot responses and tolerance of native and commercial turf grasses under drought stress in a factorial experiment based on unbalanced completely random design on the year 2006. the specious that we used in this experiment included (i) commer...

chickpea (cicer arietinum l.) is mainly cultivated in arid and semi-arid agricultural systems. drought stress is a major factor delimiting maximum yield. this research evaluated the effects of drought stress treatments on expression of cu/znsod as a gene involving in drought tolerance by real time pcr technique. to find the probable relationship between the molecular and physiological effects o...

introduction salinity has various effects on plant growth by affecting physiological processes. the decline in plant productivity under saline condition, frequently linked with the reduction of photosynthetic capability. it has been reported that efficiency of psii photochemistry (fv/fm) of numerous plant species have been decreased due to salt stress studies have shown that salicylic acid (sa...

drought stress is considered as one of the main important factors reducing field crop yield, thus leading researchers to study the related physiological characteristics may reduce drought effects. this experiment was conducted in research farm of seed and plant improvement institute (spii) in karadj, arak and jolgeh rokh for three cropping seasons (2008-2011) to evaluate drought tolerance of br...

in order to study the effects of drought stress on yield and yield components of safflower genotypes, a split plot based on randomized complete block design with four replications was performed at the research field, islamic azad university, arak, iran during summer of 2009. irrigation treatments included three levels of 100, 75 and 50% crop water requirement and four levels of safflower genoty...
