abstract to study the effect of water stress in rapeseed cultivars at the seedling stage, 10 rapeseed cultivars were evaluated at three irrigation levels [normal irrigation (control) and irrigation after depletion of 60 and 85% of available soil water]. analysis of variance showed considerable variation among cultivars. water stress reduced all of the studied morphological characteristics, espe...
burnout is a response to the chronic work stress which is prevalent mostly among the people who do people job, like teaching. the purpose of this study was to develop a valid and reliable instrument that can measure burnout in foreign language teachers. although some widely used instruments were developed before which measured burnout in teachers, a specific instrument which include specific sy...
abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
In order to investigate yield, yield components and quality traits of P. ovata and P. psyllium under water stress and plant density, two experiments were conducted at the Agriculture Research Field, University of Tehran, Karaj, in April 2005 and 2006. Two Factorial experiments based on randomized complete block design with three replications were used. The treatments were three levels of water ...
In order to study the effect of drought stress on growth of new hybrids of maize an experiment was carried out at Safi Abad Agricultural Research Center, Dezful, Iran. The experiment was arranged as a split plot in a randomized complete block design with three replications. Treatments consisted of four levels of drought stress (irrigation after 75(±5) (Control), 95(±5) (mild stress), 115(±5) (m...
Droughtis oneof the most importantfactors limitingcrop productioninarid and semiaridregions, such as Iran.In order to study drought stress in four grain sorghum varieties (Kimia, Sepideh, KGS15 and KGS23), an experiment was laid in randomized complete block design with three replications in a split plot arrangement. Water treatments were considered the main plot at three levels: irrigation afte...
In order to study the effect of irrigation withholding and biofertilizers application on quantitative and qualitative yield and grain filling duration of sunflower (Helianthus annus L.), a factorial experiment was conducted based on randomized complete block design with three replications in research field of Faculty of Agriculture and Natural Resources, University of Mohaghegh Ardabili, Iran i...
ABSTRACT- To investigate the effect of draught stress on water relations, stomatal density, chlorophyll content and yield of rapeseed, an experiment was done with four levels of drought stress including L1 (Field Capacity, FC), L2 (70% Available Water Content, AWC), L3 (50% AWC), and L4 (30% AWC), within three growth stages- including stem elongation (T1), onset of flowering (T2) and silique fo...
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...
Background and purpose: Both the condition of infertility and its treatment cause stress in couples. ÏN-Vitro Fertilization (ÏVF) is a stressful procedure for patients. Ëvidence has shown that, in addition to biomedical factors (such as age and history of pregnancy), psychological factors are related to the outcome of ÏVF treatment. Materials and methods: This cohort study was performed in 2...
