In recent years, due to the re-occurrence of extreme weathers and the water consumption increasing, Jialing River Basin is suffering drought disasters with characteristics of high frequency and aggravating influence, which seriously impacts on the urban water supply safety. A special study was carried out with respect to the drought status quo and the demand on emergency water supply, and the r...

most part of durum wheat is produced in semitropical dryland regions in iran. heat and drought stresses are the main constraints in these regions. so, identification of durum wheat cultivars with high yield and tolerant to these stresses is the main breeding strategy in dryland agricultural research institute. the genotype capeiti was evaluated at gachsaran agricultural research station from 19...

In this research Standardized Precipitation Index (SPI) in a period of 22 years(1990 to 2011) was used for zoning of climatic and agricultural drought in South Khorasanprovince, Iran. Rainfall data of six synoptic stations were collected and used for evaluationof meteorological drought. Also, reports of some local offices such as natural resources,agriculture, regional water and environment dep...

The potential protective role of priming wheat seeds with maize green extract (MGE) against the stress effects drought was studied. Pretreatment using MGE, MGE enriched polyamines (MGEPA), and treatments (irrigation deficit 30% (severe drought) or 60% (moderate versus 90% relative water content soil as a control) were applied in factorial completely randomized design. Under moderate drought, pr...

Plant drought tolerance depends on adaptations of the photosynthetic apparatus to changing environments triggered by water deficit. The seedlings three Brassica crops differing in sensitivity, oleracea L. var. capitata—white cabbage, acephala—kale, and rapa pekinensis—Chinese were exposed withholding water. Detailed insight into machinery was carried out when seedling reached a relative content...
