Biostimulants can be used in many crops growing under water deficit conditions at the seedling stage. This study tomato, Solanum lycopersicum L., seedlings commercial 150-cell trays as an experimental setup to reproduce mild drought stress effects. The method showed significant reductions growth and RGR (25%) after a seven-day experiment. Gas exchange parameters (Pn, Gs E) had significantly low...

in countries such as iran which will be faced water deficit as the main challenge in the future and the food production is going to be dependent to water recourses, wheat water-deficit tolerant and adapted genotypes release is one of the most important strategies under such a condition. in order to study the adaptation and terminal water deficit stress tolerance, fifteen bread wheat lines and c...

canopy temperature (ct) is used as a selection tool to improve crop adaptation to drought. the aim of this work was to investigate association of some photosynthetic characters with ct during grain filling in three cereal species. for this objective, a two-year study (2009-2011) was carried out in kurdistan province in western iran. four genotypes of triticale, three cultivars of bread wheat, a...

With the aim of understanding and identifying the traits which can be used as the suitable criteria for quick screening of the water deficit tolerant barley genotypes, an experiment based on randomized complete blocks design with three replications was conducted during two years to evaluate the biochemical responses of 20 barley genotypes to full irrigation and terminal water stress in the fie...

Drought is one of the most important environmental factors limiting the cultivation of ornamental plants in the green space. The effects of spermidine and salicylic acid on hollyhock (Alcea rosea L.)under drought stress were investigated. At first, the plants were sprayed with 3 doses of spermidine and 3 doses of salicylic acid (control, 100, 200 and 400 μM) for three consecut...

The purpose of this study was to alleviate the harmful effects water restriction, by applying foliar doses putrescine (0, 50, 100 and 150 mg L-1) on basil plants, as well as, understand different soil levels (60% 80% capacity) plant development. We evaluated physiology metabolic pathways plants. Basil plants under restriction reduced their growth dry matter accumulation, leaf status, physiologi...

experiment was conducted as split plot in a randomized complete block design with three replications in kermanshah to shed lights on economic analysis of deficit irrigation and integrated application of biological and chemical fertilizer son cultivation of medicinal plant borage (borago officinalis l). irrigation tritments include: a) 30% less water than crop requires invegetative, b) inreprodu...
