boron (b) toxicity is an important disorder that can limit plant growth in arid and semi-arid environments. it has been proven that use of tolerant rootstocks impede b uptake or transport to the aerial portions of plants. this may alleviate b toxicity in the scion, consequently improves the tolerance to excess b in the root zone. an experiment was conducted to find the effects of b toxicity on ...
cadmium as a heavy metal is also considered as a serious threat for the environment. this element is accumulated in soil through industrial processes as well as phosphate fertilizers and aggregates into the food chain.this study was conducted in order to investigate of different levels of cadmium effects on growth features of rapeseed(brassica napus l.) plants. root and shoot weight and height,...
due to its wide adaptability, chickpea is considered as an important crop in arid, semi-arid and in marginal lands. most important factors which limit yield of chickpea are short length of physiological growth period and susceptibility to cold and diseases, especially ascochyta rabie. releasing a chickpea cultivar with high yield and good characteristics such as cold tolerance, resistance to di...
salinity is the major limiting factor for plant growth and crop productivity. salt stress is effective on physiological characteristics, morphology, anatomy, chemical composition and water content of plant tissue. pulses are the second of food source after the cereals for human. among the pulses, the bean has special importance. in order to investigate the effect of silicon on the physiological...

Due to its wide adaptability, chickpea is considered as an important crop in arid, semi-arid and in marginal lands. Most important factors which limit yield of chickpea are short length of physiological growth period and susceptibility to cold and diseases, especially Ascochyta rabie. Releasing a chickpea cultivar with high yield and good characteristics such as cold tolerance, resistance to...
The aim of this study was to investigate the effect of irrigation period on the quality and quantity of yield and some morphological and physiological traits of three multigerm sugar beet genotypes named BP Mashhad, BP Karaj and 191. The experiment was in a split plot based on randomized complete block design , carried out at Motahari Research station of Sugar beet Seed Research Institute ...
Water stress is one of the main factors of severe damage and limitation of plant production in Iran. The paper reports a pot experiment conducted by using a factorial experiment based on a completely randomized design with three replications (each replication composed of four pots) to compare the physiological and biochemical characteristics of two varieties of tuberose (double- and single-flow...
