iran is among the world's arid and semi-arid countries. drought stress is one of the most important environmental stresses affecting fruit trees and considerably can cause yield reduction. persian walnut (juglans regia l.) with significant area harvest is one the most important nuts in iran which require sufficient amounts of water for optimal growth and efficiency. in order to study the e...

the objective of this research was to evaluate the effect of different concentration of salicylic acid on enhancement germination characteristics of sanguisorba minor l. under salt and drought stress. the experimental design was factorial arranged in a completely randomized block design with four replications. treatment were combination of 5 levels of salt and drought stress, separately (0, -0....

kochia (kochia scoparia l. schard) is an annual, halophyte and drought resistant plant that can be irrigated with saline water and a valuable source for forage under drought and saline ecosystem. in order to evaluate the germination characteristic of kochia under different temperatures and salinity stress levels, an experiment was conducted at physiology lab of ferdowsi university of mashhad, i...

This study was conducted in two phases: 1) to investigate the effect of drought stress on relative water content and proline of leaf and 2) to evaluate the effect of drought stress and potassium concentrations in nutrient solution on the lily (Lilium longifolium × Asiatic cv. Termoli). Based on a completely randomized design in mixture of sand and perlite medium and in three levels of potassium...
