| Abstract: | An experiment was conducted to study the effect of exogenous nitric oxide(NO) on the vase life and physiological indexes of cut lily flowers using sodium nitroprusside(SNP) as NO donor and Methylene blue(MB-1) as NO scavenger.Results showed that NO released by 0.1mmol·L-1 SNP could significantly extend the vase life and increase the maximum flower diameter of cut lily flowers,prolong the time the flowers reach the maximum flower diameter,and increase the fresh weight of flower stems.Moreover,SNP could reduce the degradation rate of soluble protein,markedly enhance activities of SOD and POD in the petals,and inhibit the increase of MDA and free proline contents.However,as a scavenger of NO,MB-1 could partially or entirely reverse the active effects of NO on the physiological indexes of cut lily flowers. |
