two glasshouse and field experiments were conducted to assess the effects of root system, water uptake, water use efficiency and early vigor on yield and drought tolerance of bread wheat in two successive farming seasons (2009-11). the experiments were conducted as randomized complete block design and two-year results analyzed as combined design. considerable genetic variation was observed amon...

Cynara cardunculus var. scolymus L. is a herbaceous perennial plant that could be drought tolerant once established after the first year. To evaluate the effects of water stress on growth parametersand forage quality of this plant, a field experiment was conducted using a randomized complete block design with three replications in Isfahan, Iran during 2013-2015. Treatments wer...

The Fig (Ficus carica.L) is a woody perennial crop, cultivated worldwide in subtropical regions. Since, salinity is the main concern of fig industry, therefore, studying the pattern of ion absorption and accumulation contribute during the stress in different plant organs can lead understanding the mechanism of tolerance/sensitivity. So, during 2016-2017, seven fig cultivars (‘Sabzʼ, ‘Siyahʼ, ‘S...

silicon is known to ameliorate the deleterious effects of drought on plant growth. we evaluated growth of wheat (triticum aestivum l. cv. chamran) under water-deficit stress induced by polyethylene glycol as affected by si application. in this article, the effects of si (as potassium silicate) on some parameters related to growth, chlorophyll concentration relative water content (rwc), electrol...

in order to study the reaction of barley genotypes to drought, an experiment was conducted in a factorialdesign based on crd for two wild ecotypes and four crop genotypes of barley in greenhouse. in thisstudy, the barley genotypes and wild ecotypes as the first factor and irrigation treatment with three levelsinclude 70 percent of water holding capacity of soil, 30 and 10 percent as the second ...

Water deficit and phosphate (Pi) deficiency adversely affect growth and biological nitrogen fixation (BNF) of legume crops. In this study, we examined the impact of interaction between soil water conditions and available soil-Pi levels on growth, nodule development and BNF potential of nine cowpea varieties grown on dry savanna soils. In our experimental design, soils with different available s...

this research was performed to investigate the combined effect of soil salinity and compaction on some physiological characteristics of corn. for this purpose a factorial pot experiment on the basis of completely randomized design with three replications was performed. the experimental factors were three levels of soil salinity (saturated paste extract electrical conductivity 1.5, 2.5 and 4.5 d...

we investigated the response of sea buckthorn to drought in a nursery experiment that has been studied for the first time in the world for iranian sea buckthorn. biomass and physiological differences in response to drought were compared between four elaeagnus rhamnoides seedlings inhabited in qazvin province origin seeds of iran. the experimental design included four water regimes including 2, ...
