Among the environmental barriers to plant growth and yield, drought, an icon of arid and semi-arid regions is the most important factor in reducing production. Teucrium polium L. is one of the most important medicinal plants of the family Lamiaceae that exists in these areas. In order to study the effect of drought stress on some physiological and morphological traits of Teucrium polium L., an ...
In order to investigate drought stress and plant density the yield, yield components and protein of spotted bean grain (cultivar Talash), an experiment was carried out as split plots in randomized complete blocks with three replications in Yasouj, in 2012. Factors of the test including irrigation in three levels; without stress (control treatment), water stress in vegetative stage (interrupting...
in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...
Drought stress is a key environmental factor limiting the growth and productivity of plants. The purpose of this study was to investigate the physiological responses of Camptotheca acuminata (C. acuminata) to different drought stresses and compare the drought tolerance between the provenances Kunming (KM) and Nanchang (NC), which are naturally distributed in different rainfall zones with annual...
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...
Relative water content (RWC) in plants is one of the most important biochemical parameters and its deficiency limits efficiency of photosynthesis and crop productivity. The scientific reports on using spectroscopy in detecting drought stress for sesame plants are very rare. In this study, the possibility of identifying water stress in two sensitive (Naz-Takshakhe) and resistant (Yekta) genotype...
the following study was conducted at the research station of horticultural sciences (university of tehran, karaj) to investigate the effect of different irrigation levels and fruit site on the stalk upon the traits of: sink-source relationship, yield, and fruit quality in two iranian melon cultivars. the statistical design was a split split-plot of three replications. treatments consisted of a...
As increasing of disaster such as drought and pest invasion in recent decades, it is essential to find out practical approaches in optimizing water use and water management for reduce the adverse effects of this disaster in agriculture. In order to study the effects of water stress and pest stress on corn yield, an experiment was conducted in the research farm of Isfahan University of Techno...
