Abstract
Grafting improves the yields of the melon growing in the protected cultivation and disease resistance, but the same time it delays the fruit ripening and declines the fruit qualities. In order to find out the physiological factors of melon fruit ripening being delayed by grafting, the effects of spraying exogenous ABA on ethylene biosynthesis and the key enzyme genes' expression of grafted muskmelon were studied during the ripening period using the white pumpkin 'Shengzhen NO.1' as rootstock for the approach grafting, and the muskmelon 'New Seoul Honey' as scion. The results showed that treatment of exogenous ABA enchanced the ethylene productions, the peak of ethylene productions appeared in advance for 3 days and the peak value was increased by 13.83% comparing with that of the grafted muskmelon during the grafted muskmelon fruit ripening period. The treatment of exogenous ABA obviously improved the ACC contents, increased the ACS and ACO activities of grafted muskmelon fruit. It also improved the relative expression of Cm-ACS1, Cm-ACS2 and Cm-ACS3 m RNA, and the peaks of them appeared in advance for 3 days comparing with that of the grafted muskmelon. Meanwhile the treatment of exogenous ABA inordinately enchanced Cm-ACO1, Cm-ACO2 and Cm-ACO3 m RNA relative expression of grafted muskmelon, especially promoted Cm-ACO1 m RNA relative expression. And it made the peak time of Cm-ACO1 m RNA relative expression for 3 days in advance. Thus it can be seen that the influence of exogenous ABA on Cm-ACO1 m RNA relative expression of grafted muskmelon fruit could be the key of the rise in ethylene productions and peak time in advance.
