Abstract
In this trial,the field experiments were carried out by seed soaking and foliage spraying at 5-leaf stage,respectively. Three rapeseed hybrids( Brassica napus L.) were used as experimental materials to study the effects of sodium selenite( Na2SeO3) on their seedling emergence and chlorophyll content under simulation waterlogging stress. The results showed that the selenium solution had no significant effects on the seedling emergence rate,but the interaction between varieties and selenium concentrations had significant effects( P 0. 05),which were probably positive or negative. Spray selenium solution with concentrations of 21- 27 μg / mL could significantly( P 0. 01) raise the chlorophyll content of young rapeseed plants at the 5-leaf stage. Responses of the three rapeseed varieties were different,of which the variety 09-3 exhibited the highest chlorophyll content and the most vigorous growth after spraying. So,it is suggested that the concentrations of21- 27 μg / mL selenium solution could be applied to rapeseed seedling to enhance its resistance to waterlogging stress in practical cultivation.
