This experiment was conducted to evaluate the effect of vermicompost, pistachio kernel and shrimp shell on the immobilization and availability of Cd, Pb and Zn in corn in polluted soils. Treatments consisted of two levels of pistachio kernel, shrimp shell and vermicompost (5 and 10 % w/w). In control treatment, no amendment was added to the soil. The experiment was carried out as a completely r...

nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...

abstract growth retardants are new chemical organic compounds that increase period of flowering, leave chlorophyll, lateral shoot number, flower number and decrease vegetative growth. they also increase dry, cold and heat tolerance. paclobutrazol and cycocel are examples of these compounds. this study was conducted to evaluate the effect of paclobutrazol and cycocel on some quantitative and qua...

the leaf nitrogen content is generally accepted as an indicator of food quality and as a factor affecting host selection by phytophagous insects. the alate pea aphids (acyrthosiphon pisum harris, aphididae) were given a choice among non-nodulated pea plants (pisum sativum l.) supplied with one of four nitrate-n levels (0, 3, 15 and 30 mm). when whole plants were exposed to aphids for 7 days, th...

Chloride is an essential micronutrient for plants growth however it accumulates in large amounts in tobacco plants rapidly. To evaluate the effects of chloride concentrations in irrigating water on yield and growth indices of tobacco plant which has an important economic value, an outdoor pot experiment was established in completely randomized design during 2010 crop year at Guilan Tobacco Rese...

Shoot growth, chlorophyll concentrations, gas exchange and starch concentrations were studied in lychee (Litchi chinensis Sonn.) seedlings of cultivar "Wai Chee" grown in a heated greenhouse at Nambour in subtropical Australia (27 degrees S). We also examined the effects of shoot defoliation and root pruning on leaf expansion. Shoot growth showed a rhythmic cycle under constant greenhouse condi...

Ultraviolet radiation as one of important stressful environmental factors, has deleterious effects on  plant physiological processes and growth. Plants confront with this conditions that produce ROS, via specific physiological mechanisms. This study to investigate the effect of UV-C radiation on the physiological responses in radish (Raphanus sativus L.cv), the plant with one year old and ...

the water deficiency is one of the serious problems in the arid zones. in order to investigate the effect of cycocel on different growth aspects of two olive cultivars (mary and mission), a greenhouse experiment was conducted using three factors of: cycocel at three levels (0, 500 and 1000 mg l-1), irrigation of three levels (irrigated at 5, 10 and 15 days intervals) and tow olive cultivars (ma...

Chloroplasts isolated from Populus deltoides leaves were used to study age-dependent changes in the rate of cyclic photophosphorylation. Single leaves were used to measure CO(2) fixation by leaf discs, chlorophyll concentration, and ATP synthesis. The ability of chloroplasts to synthesize ATP diminished steadily from the time of full leaf expansion, regardless whether the results are expressed ...
