Green roofs are gaining momentum in the arid and semi-arid regions due to their multiple benefits as compared with conventional roofs. One of the most critical steps in green roof installation is the selection of drought and heat tolerant species that can thrive under extreme microclimate conditions. We monitored the water status, growth and survival of 11 drought-adapted shrub species grown on...

plant cover is one of the most important factors affecting infiltration rate of water into the soil and decreasing runoff. distribution of plants in arid and semi-arid areas is almost patchy and form different patterns. one of the fascinating patterns is ring-shaped growth pattern. ring patterns of varying size are formed by clonally reproducing grasses, sedges and even shrubs growing in resour...

although water deficiency has been seriously taken up as a subject in reducing crop production in arid and semi–arid areas, nevertheless little information has been published regarding its effects on seed quality. to evaluate the effects of irrigation regimes (full irrigation (control), irrigation until flowering stage, irrigation until doughing stage and irrigation until eight-leaf stage) on g...

abstract low water holding capacity of soilless substrates increases water stress and waste of nutrient solution. irrigation time management can reduce such problems. in this research, responses of hydroponically cultured greenhouse strawberries were evaluated under different irrigation schedules. in first step, plant daily water need was estimated and then delivered to plants through two metho...

Arid and semi-arid lands cover more than one-third of the earth’s terrestrial area are typically characterized by rainfall scarcity, higher temperatures evapotranspiration, salinization, nutrient-poor soil, a paucity vegetation [...]
