studying the physiological responses of linseed genotypes to water deficit stress may be helpful in recognizing the linseed resistance mechanisms to the latter stress factors. therefore, a split plot rcbd field experiment was conducted with three replications to explain interrelations of leaf chlorophyll, proline and soluble carbohydrates content and grain yield of six linseed genotypes under t...
In order to evaluate effect of plant density and water deficit on the growth, yield and yield component of soybean, an experiment was carried out in split plot design based on RCBD with four replications at the research station of Seed and Plant Improvement Institute in Karaj-Iran in 2006. In this experiment, water deficit treatment in three levels was placed as main plot (water withholding at ...
drought, ultraviolet radiation and atmospheric co2 are some three environmental factors that seriously affect future food security. the objective followed in the present research was to study the effect of two levels of carbon dioxide (400 and 900 ppm), ultraviolet radiation (uv a, b and c with intensities of 18, 25 and 40 microw.cm-2 respectively) and water deficit (%100 and %60 of field capac...
