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 the different levels of cadmium effects on growth features of rapeseed (Brassica napus L.) plants. Root and shoot weight and heig...

abstract background and objectives: soil salinity is one of the most important limited factors of plant productions. physiological drought resulting from salinity stress is one of the main reasons of limiting water absorption from soil. moreover, increasing the salt absorption by plants cause to disorder in physiological and cellular processes. spearmint (mentha spicata l.) is from lamiaceae fa...

to study the physiological and morphological relationships of two clover species affected by herbicides, pursuit experiment in a factorial based on randomized completely design with 3 replications at the damavand in 2012. the first factor consisted of two species of trifolium pretense l. and trifolium alexandrinum l. and the second factor consisted of three levels of herbicide pursuit (0, 0.5, ...

a pot experiment was conducted to evaluate the extract biochemical variations among 25 spearmint population. the experiment was a randomized complete design (rcd) with 25 treatments (population) and three replications. for this purpose, three rhizomes with 5 cm length were selected and planted in each pot. all pots were kept out side. the plant samples of all treatments were harvested at full f...

this study was aimed to study the ways of removing dormancy period and accelerating pre-sowing tuber germination to provide simple tools to apply by farmers. for this purpose, intact tubers, exposed tubers to released ethylene and sliced tubers were examined in respect to germination characters, bud length, starch, anthocyanin and chlorophyll contents and amylase activity. relative amount of an...

drought stress is the most important factor that reduces yield in crops including chickpea and causes some changes in seed composition. this study was performed in order to evaluate the effects of drought stress and starter nitrogen fertilizer on four cultivars of chickpea. experiment was performed in a split-factorial using randomized complete block design with three replications. drought stre...

turf is one of the most important ground covers and it is one of the main elements ofurban landscape design. plant growth regulators, such as growth inhibitors, are widelyused in turfgrass management to suppress shoot growth and inflorescences production.this experiment was conducted to determine the interactive effects of trinexapac-ethyl(te) and salinity on the growth, visual quality, and che...

in recent years application of plant growth regulators especially growth retardants, has been significantly increased. trizols (paclobutrzol and trinexapac-ethyl) as the most effective and least harmful growth retardants, induce more dwarf and denser cover plants with both darker and thicker leaves.  therefore, an experiment based on completely randomized block design with 16 treatments and 3 r...
