| Abstract: | Six transgenic lines of ground cover chrysanthemum over-expressing AtDREB1A that conferred strong tolerance to high temperature and drought stress were treated for dehydration at different temperature conditions,using ’Wild Type’ as the control group.The drought resistance of different chrysanthemum lines was studied by measuring physiological indices related with drought tolerance.A comprehensive evaluation on drought resistance and water saving ability of different lines were made according to the variance analysis and the subordinate function values.Results indicate that,five transgenic lines are better than the control plants,and there is a significant difference(p<0.05) in drought tolerance and water saving ability between three of them and the control.One transgenic line is not as good as the control,but there is no significant difference between them. |
