Physiological Response of Four Widely Cultivated Sunflower Cultivars to Cadmium Stress

Response of some vegetative and physiological traits of Iranian and foreign grape cultivars to drought stress

Drought stress, as the most important environmental stress, severely disrupts plant growth and limits production and yield more than any other environmental factor. Investigation of the role of drought stress conditions on plant morphological, physiological and photosynthesis characteristics may provide a tool to understand the basic drought resistance. To investigate the drought tolerance of I...

Cadmium accumulation and physiological response of sunflower plants to Cd during the vegetative growing cycle

The effects of soil cadmium (Cd) contamination on Cd accumulation and distribution, growth and physiological responses of sunflower plants were investigated. Plants were subject to six levels of soil contamination (from 2.5 to 15 mg Cd kg/soil) with an untreated control, from the emergence of the cotyledon leaves until the harvest, when plants were at the flower bud stage. An overall increase o...

Response of sunflower cultivars of Iroflor to water deficit stress and methods of biophosphate application in the Miandoab area

In order to evaluate the effect of water stress on sunflower cultivars of Iroflor in different stages of growth and methods of biophosphate consumption, a factorial experiment was conducted in a randomized complete block design with four replications. Water deficit stress in four levels including control (non-stress), stress in vegetative stage, stress in reproduction stage and stress in both v...

Assessment of Root Growth and Physiological Responses of Four Bread Wheat (Triticum aestivum L.) Cultivars to Salinity Stress

Enlarged root systems that extend into the salt affected soil improve water and nutrient capture by plants and can increase plant productivity. In order to examine root system characteristics of four bread wheat cultivars contrasting in salt tolerance (Arg, Ofoq, Tajan and Morvarid) a greenhouse experiment was conducted with applying two salinity levels (0 and 150 mM NaCl) on plants grown in PV...
