The sucrose non-fermenting 1-related protein kinase 2 (SnRK2) family members are plant unique serine/threonine kinases which play a key role in cellular signaling in response to abiotic stresses. The three SnRK2 members including SRK2D, SRK2I and SRK2E are known to phosphorylate major abscisic acid (ABA) responsive transcription factors, ABF2 and ABF4, involved in an ABA-dependent stress signal...

abstract: deficit irrigation technique can be used for produce more yield for every unit of irrigation water, and cause to increase crop economical benefit. main purpose of deficit irrigation is high water use efficiency with decreasing in irrigation sufficiency. in this research potential of cropwat model in deficit irrigation management for two crops, wheat and barley in karaj climate was stu...

This research was carried out to study the effect of deficit irrigation and saline water on yield and yield components of maize (KSC-500) during different growth stages for Ahwaz climatic condition in the farming years 2010-2011. This research performed in three independent experiments according to a randomized complete block design with split plot layout in three levels of irrigation water and...

Now days, turf management has encountered with water deficit, mostly due to low precipitation also industrial, agricultural and household demand and consumption. So, the objective of this project was to identify drought tolerance of warm and cool season turfgrass cultivars to different levels of regulated-deficit irrigation. The field experiment was set out in a split-plot based on completely r...

Water deficit is one of the major stresses affecting plant growth and productivity worldwide. Plants induce various morphological, physiological, biochemical and molecular changes to adapt to the changing environment. Safflower (Carthamus tinctorius L.), a potential oil producer, is highly adaptable to various environmental conditions, such as lack of rainfall and temperatures. The objective of...

We compared the metabolic responses of leaves and roots of two Eucalyptus globulus Labill. clones differing in drought sensitivity to a slowly imposed water deficit. Responses measured included changes in concentrations of soluble and insoluble sugars, proline, total protein and several antioxidant enzymes. In addition to the general decrease in growth caused by water deficit, we observed a dec...

A field experiment was conducted during 2001-2003 to evaluate the effect of water stress on the yield and yield components of four rice cultivars commonly grown in Mazandaran province, Iran. In northern Iran irrigated lowland rice usually experiences water deficit during the growing season include of land preparation time, planting, tillering stage, flowering and grain filing period. Recently d...

water deficit, ultraviolet radiation and carbon dioxide enrichment are the most important environmental factors in global climate change. this research was conducted in tarbiat modares university, research greenhouse and the objective of that was to study the effects of three levels of carbon dioxide (500, 900 and 1300 ppm), uv-radiation (uv-a, b and c with intensity of 18, 25 and 40 µw.cm2 res...

Salinity and water stress reduces the ability of plant to take up water and decrease growth rate, photosynthesis rate (An) and stomatal conductance (gs) of plants. In this study, effects of deficit irrigation with different salinity levels and planting method (in-furrow and on-ridge) as strategies for coping with water and salinity stress on physiologic properties of rapeseed was investigat...
