Grape Composition under Abiotic Constrains: Water Stress and Salinity

Grape Composition under Abiotic Constrains: Water Stress and Salinity

Water stress and increasing soil salt concentration represent the most common abiotic constrains that exert a negative impact on Mediterranean vineyards performance. However, several studies have proven that deficit irrigation strategies are able to improve grape composition. In contrast, irrigation with saline waters negatively affected yield and grape composition, although the magnitude of th...

Regulation of root water uptake under abiotic stress conditions.

A common effect of several abiotic stresses is to cause tissue dehydration. Such dehydration is caused by the imbalance between root water uptake and leaf transpiration. Under some specific stress conditions, regulation of root water uptake is more crucial to overcome stress injury than regulation of leaf transpiration. This review first describes present knowledge about how water is taken up b...

Water Salinity Under Heat Stress in Grazing Conditions

Growth and Chemical Composition of Pistachio Seedling Rootstock in Response to Exogenous Polyamines under Salinity Stress

In order to evaluate responses of a pistachio seedling rootstock (Pistacia vera L. cv. Ghazvini) to NaCl induced salinity stress and potential protective role of exogenous spermine and spermidine on NaCl induced salinity stress, a greenhouse experiment was conducted during growing season of 2009. The NaCl treatments, involving 800, 1600, and 3200 mg NaCl per Kg of soil for 90 days, suppressed g...

Effect of biostimulants on water content and micronutrients and macronutrients of Puccinellia distans under salinity stress

Abstract: Biostimulants are a variety of compounds of plant and animal origin that are used to improve the quality of plant growth. In this study, which was conducted in 1399, the effect of commercial biostimulant Algabon®, algal biostimulant [seaweed extract (SWE)], and namid (amino acid biostimulant) on the plant Puccinellia distans to reduce the effects of salinity stress by improving growt...
