Abstract:
Four different concentrations (10,20,40,80 mg·L-1) of GA4+7+clopidomide (1∶1) were sprayed on the leaves of Lilium bicolor ‘Thalita’.The plant height,stem diameter,leaf area and other indicators were measured to explore the effects of GA4+7+clopidomide on the growth of ‘Thalita’，in order to provide reference for promotion of lily.The results showed that,20 mg·L-1 GA4+7+clopidomide had the greatest promoting effect on the flower bud diameter and leaf area of ‘Thalita’,which were 14.18% and 55.13% higher than those of the control,and the stem diameter showed a certain inhibition effect with the increase of GA4+7+clopidomide concentration;the comprehensive effect of 20 mg·L-1 GA4+7+clopidomide on flower bud opening rate and flowering period was the best;80 mg·L-1 GA4+7+clopidomide had the best comprehensive effect on flower bud opening rate and flowering period GA4+7+clopidomide had the best effect on plant height promotion of ‘Thalita’,which was 2.67% higher than that of the control;the fresh weight and root length of all treatment groups were lower than that of the control,and the effect of 20 mg·L-1 GA4+7+clopidomide was the most obvious,which was 36.77% and 48.18% lower than that of the control,respectively.Comprehensive comparison showed that 20 mg·L-1 GA4+7+clopidomide had the greatest effect on the growth of ‘Thalita’ and the effect was better.
