the development of seminal and lateral root system plays a major role in plant access to water and nutrients under abiotic stress, especially salinity. in order to understand the relation between root growth responsesand shoot physiological indices oftwo bread wheat cultivars contrasting in salt tolerance (kavir and shiraz), a greenhouse experiment was conducted with two salinity levels (0 and ...

Peppermint (Mentha piperita L.) is one of the most important plants producing essential oil. An experiment was carried out using a randomized complete block design with 3 replications to study the effect of salinity stress on growth parameters, essential oil percent of peppermint. 4 levels of salinity solution containing 0, 50, 100 and 200 mmol NaCl was applied in irrigation plantings ...

Plant growth and development was affected greatly through salinity. Appropriate nutrients application on salinity condition can reduce its harmful effects and increased productivity of salinized soils. A pot experiment was carried out in 2007 in cs Lab., Department of Agronomy, Kyungpook National University, Korea to assess the effects of potassium nitrate on Gycine max (Var. Daewonkong) under ...

Arsenic (As) is a well-known toxic metalloid found naturally and released by different industries, especially in developing countries. Purple nonsulfur bacteria (PNSB) are known for wastewater treatment and plant growth promoting abilities. As-resistant PNSB were isolated from a fish pond. Based on As-resistance and plant growth promoting attributes, 2 isolates CS2 and SS5 were selected and ide...

abstractin order to evaluate the effect of vermicompost and humic acid on quantitative and qualitative traits of sod turf, a factorial experiment based on completely randomized design with three replications was established in research farm in shahrekord university. treatments were vermicompost (zero, 5, 10 and 15 v/v percent) and humic acid (zero, 150 and 250 g/m2), respectively. some traits s...

Root architecture is an important regulator of nitrogen (N) acquisition. Existing methods to phenotype the root architecture of cereal crops are generally limited to seedlings or to the outer roots of mature root crowns. The functional integration of root phenes is poorly understood. In this study, intensive phenotyping of mature root crowns of maize was conducted to discover phenes and phene m...

Clonal propagations of shoot or root fragments play pivotal roles in adaptation of clonal trees to environmental heterogeneity, i.e. soil nutrient heterogeneity and burials after disturbance. However, little is known about whether burial orientation and nutrient supply can alter the effects of fragment traits in Populus. Shoot and root fragments of Populus deltoides × P. simonii were subjected ...
