in order to study the effects of water deficit stress and foliar application of chitosan in safflower (carthamus tinctorius l.), a pot experiment was conducted in 2009. experimental design was a randomized complete block in factorial arrangement with three replications. experimental factors were water deficit levels (unstressed (control) and 70% available water depletion from soil (water defici...
Water stress is one of the most important abiotic limiting factors that restricts growth, development and productivity of horticulrural crops. In vitro methods have been successfully used for evaluating water deficit stress in plants. In this regards, responses of four Iranian grapevine genotypes to drought stress induced by polyethylene glycol 6000 at -5, -5.24, -5.65, -6.24 and -7 bar were...
Introduction: Increase in life expectancy in communities tends to increase in number of elderly people and increase in prevalence of memory deficit. This study is aimed to investigate the relationship between memory deficit and some related factors such as stress oxidants. Methods: In a cross-sectional study, 220 people were studied. After physical examination and blood sampling, they were in...
In order to investigate the effect of Hexaconazole (HEX) on quantitative and qualitative characteristics of two soybean (Glycine max L.) cultivars under water deficit stress, an experiment was conducted in the Faculty of Agriculture of Tarbiat Modares University in the year 2010-2011 as a factorial experiment in randomized complete block design arrangement. Factors examined in this study were s...
to evaluate the effects of water deficit stress in barley germplasm collection of national gene bank ofiran, 25 genotypes collected from arid and semi arid provinces of iran and 3 sample cultivars werestudied in two environments including: non-stressed and water deficit stress. agronomical, phenologicaland morphological traits were measured. stress indices were calculated to determine tolerant ...
mechanisms of tolerance to water deficiency stress for introducing sunflower hybrid was investigated by a two-factor experiment as a split plot design based on rcbd was at the research station in alborz province, hashtgerd region, iran in 2013. irrigation rates (irrigation after 50, 100 and 150 mm cumulative evaporation from class a evaporation pan) were considered in the main plots and sunflow...
Among the crops, cereals have been special important and triticale is the most successful man made cereal. In present research, water deficit stress effects on 19 triticale genotypes (X Triticosecale wittmack) and two wheat cultivars (Triticum aestivum), Shiraz (sensitive to water deficit stress) and Kavir (tolerant to water deficit stress) were tested. Therefore, two separate field experiments...
introduction : behavioral disorder is one of the most prevalent psychological disorders among children. it can affect the psychological and social functions of all members of the family. this study has been caring out with the aim of determining the effect of positive parenting program (3p) on depression, anxiety, and stress level of mothers who had children suffering from attention deficit hyp...
in order to identify drought stress tolerance in rapeseed, nine commercial rapeseed cultivars (opera, karaj1, karaj2, karaj3, zarfam, okapi, talayeh, licord and modena) were evaluated under two conditions (normal and drought stress) in kangavar region in the west iran in 2014-2015 growing season. this research was carried out in a split plot experiment based on completely randomized design in f...
this study was conducted to evaluate the impact of deficit irrigation and growth stages on yield and yield components of potatoes and water use efficiency. a field experiment was conducted at shahrekord agricultural research station over three years of crop seasons using a randomized complete block design with three replications. plots were assigned to five levels of deficit irrigation treatmen...
