Wheat leaf non-sequential senescence at the late grain-filling stage involves the early senescence of younger flag leaves compared to that observed in older second leaves. On the other hand, sequential senescence involves leaf senescence that follows an age-related pattern, in which flag leaves are the latest to undergo senescence. The characteristics of sugar metabolism in two sequential senes...
to study the effects of urea foliar spray at different plant growth stages on grain yield and protein percentage of two dryland wheat varieties of sardari and azar 2, an experiment was conducted in east mangor agricultural station of mahabad in 2007– 2008. the experiment design was split plot based on randomized complete block design with three replications. treatments were 50 gr×10 m-2 n as ur...
partitioning of photoassimilates between the sinks is one of the most important physiological processes related to the yield of crops which are affected by drought stress. therefore, the effect of drought stress in flowering and grain filling stages, on the percentage partitioning of photoassimilates among different organs was studied in 14 rapeseed cultivars in a split plot experiment based on...
APSIM Nwheat is a crop system simulation model, consisting of modules that incorporate aspects of soil water, nitrogen (N), crop residues, and crop growth and development. The model was applied to simulate aboveand belowground growth, grain yield, water and N uptake, and soil water and soil N of wheat crops in the Netherlands. Model outputs were compared with detailed measurements of field expe...
To evaluate the response of wheat genotypes to terminal drought stress and to identify drought tolerant and sensitive genotypes, 20 wheat genotypes were compared in two stress and normal conditions, in a field experiment carried out at the Experimental Farm of College of Agriculture, Shiraz University, Shiraz, Iran, as a split-plot arrangement using complete randomized blocks design with four r...
Drought stress leaves deleterious effects on growth of maize plant while potassium plays an important role in reducing such deleterious effects. To study the role of potassium on maize plant grown under drought stress an experiment was conducted at Postgraduate Agricultural Research Station, Faisalabad, Pakistan. Maize hybrids 32-F-10 (drought tolerant) and YH-1898 (drought sensitive) were grow...
This study was conducted in Research Farm of Isfahan University of Technology to evaluate some of the agronomic and physiological traits and grain yield potentials of ten bread wheat cultivars using a split plot design with three replications. Main and sub plot consisted of optimum and stress moisture treatments (irrigation after 70±3 and 130±3 mm evaporation from class A pan) and wheat cultiva...
Understanding the nitrogen remobilization by plant, in order to obtain cultivars with higher quality, has specific importance in plant physiology. In this experiment, a bread and a durum wheat cultivar, were treated with different rates and times of nitrogen application, by using split factorial on the basis of randomized complete block design with three replications at Shiraz region during 200...
مطالعه روابط رگرسیونی شاخصهای فیزیولوژیکی برنج در مراحل مختلف رشد در شرایط آب و هوایی استان خوزستان
This study aimed to investigate the relationship between morphophysiological and phenology traits with grain yield to determine the best indices of direct and indirect selection in the field of genetic improvement of aerobic rice grain yield in Khuzestan province with 12 aerobic rice genotypes. The traits such as include the grain yield as the dependent variable and total dry matter, panicle we...
in order to evaluate the effects of different levels of water and plant density on yield, yield components, morphological and physiological characteristics of a new corn hybrid (ksc 500), an experiment was carried out in 2006 in karaj area. the experimental design was split plot based on randomized complete blocks design with three replications. main plots were three irrigation levels: 75%, 100...
