The redistribution of nutrients in the cells seriously affected the commodity value and edible value of garlics cape. This paper studied the physiological mechanism that NO participates in the process of GA3 delaying garlics cape senescence via the cell inclusions transport,in order to provide experimental basis for the storage and refreshing of such kind of horticultural products. The basal part of garlic scape were treated with GA3,SNP,GA3+L-NAME,GA3+Na2WO4,GA3+HB or SNP+PP333 for three hours,respectively...
