in order to evaluate the effects of drought stress at different phenological stages on growth indices of chickpea (cicer arietinum l.) cultivar jam, an experiment was carried out at the research greenhouse of faculty of agriculture, ferdowsi university of mashhad, using a completely randomized design with four replications. drought stress was applied by preventing irrigation until the soil mois...
In order to evaluate the genetic diversity of oily sunflower lines, screening drought tolerance indices and identification of drought tolerant lines, 100 oily sunflower lines were evaluated in a simple lattice design under both well-watered and water-limited stressed conditions in 2016. Based on the potential (Yp) and stress (Ys) yield, quantitative drought tolerance criteria such as: mean prod...
Drought is one of the major environmental limiting factors in the global agriculture. Exploiting of crop yield potential and increasing yield stability of them in drought and drought-prone regions can be guaranteed to feed the world’s growing population. For this purpose, in order to assess the late season drought tolerance genotypes and determining of tolerant them using stress tolerance ...
in order to evaluate the effect of different levels of drought stress and nitrogen fertilizer on growth of strawberry plants, present study was conducted in the mazandaran province in 2010. experiment was carried out as factorial based on randomized complete block design with three replications. drought stress treatments (30, 50 and 70% maximum allowable depletion of moistur (mad)) and nitrogen...
An in-depth understanding of the effects of drought stress on plant metabolism is necessary to improve the drought tolerance of wheat and to utilize genetic resources for the development of drought stress-tolerant wheat varieties. In this study, the profiles of 58 key metabolites produced by wheat seedlings in response to drought stress were investigated to determine various physiological proce...
considering forage grass species, germination is one of the important stagesconcerning the growing stage that is often influenced by environmental stresses,particularly salinity and drought stresses. thus, this study aims to assess the effects ofsalinity and drought stresses on germination characteristics and seedling growth of desertwheatgrass, agropyron desertorum (fisch. ex link) schult. in ...
abstract drought is a natural creeping event that starts due to lower moisture compared to normal condition. this phenomenon impacts all aspects of human activities. however there is neither any detailed definition nor a general and proper index for drought monitoring. in this study, fuzzy logic has been applied to deal with inherent uncertainties of the real world data. we presented a fuzzy mo...
Droughts affects on agriculture and water consumption management through LU/LC and water resources changes in western mountainous areas of Iran. The aim of this study was to investigate terrestrial and remote sensing drought indices and their effects on LU/LC and ground water level in Razan-Ghahavand watershed. Precipitation trend in two stations and water level trend in six piezometric well we...
