the response of plants to drought stress depends on several factors including the plant developmental stage and the length and severity of the stress applied. common bean (phaseolus vulgaris l.) is the most important pulse crop that is cultivated worldwide for human consumption. understanding of the mechanisms responsible for its response to drought is, therefore, essential. an increasing numbe...

water is the most limiting factor in irrigated agriculture, mainly in mediterranean environments, as in the case of southwest spain. in this area, almond is one of the most valuable crops due to its high drought tolerance. this work examines the crop coefficients (kc) based on four drainage lysimeters installed in an experimental young almond orchard. complementary, two deficit-irrigation treat...

abstract in order to investigate the response of two species of p. ovata and p. psyllium to water deficit. the experiment was conducted during 2009 growing seasons in the agriculture research station ferdowsi of mashhad. for this purpose a split plot experiment based on complete randomized block design with three replications was used. four irrigation levels (4000, 3000, 2000, 1000 m3/ha) alloc...

drought is a complex natural phenomenon that can occur in any climate. hydrologic drought in the river flow of arid and semi-arid areas causes serious shortages, threatens the quality of life, and impacts on the economy. understanding this feature is then essential for the management of water resources. hydrologic drought in the sense of deficient river flow is defined as the periods that river...

Grapes are one of the major fruit crops and they are cultivated in many dry environments. This study comprehensively characterizes the metabolic response of grape berries exposed to water deficit at different developmental stages. Increases of proline, branched-chain amino acids, phenylpropanoids, anthocyanins, and free volatile organic compounds have been previously observed in grape berries e...

salmas plain is located at the west of uremia lake and at the 75 km of north of uremia city. the main river of the plain, called zulachai, is drained into uremia lake. salmas aquifer is one of the coastal aquifers of uremia lake and has hydraulic connection with the lake. the recent draught occurrences and increased water consumption in agriculture and drinking sections water have not only caus...

Water is the most limiting factor for plant growth and crop productivity (Kramer, 1983), and water-deficit stress adversely affects crop growth and yield throughout the world (Boyer, 1982). Crop yields are being reduced by drought and the increasing scarcity of water for irrigation, and changing world climatic trends may increase the severity of the problem (Le Houerou, 1996). Water availabilit...

A field experiment, laid out in Randomized Complete Block Design (RCBD) with split plot arrangement having four replications, was conducted at the south edge of Loess Plateau, Shaanxi, China to evaluate the responses of winter wheat and summer maize to different water saving management practices involving four mulching and irrigation treatments, i.e., plastic mulch ridge and straw mulch furrow ...
