absicsic acid catabolism is largely categorized into two types of reactions, hydroxylation and conjugation
(Nambara and Marion-Poll, 2005). Therefore, ABA extracted in our study may be primarily catabolized to phaseic acid or ABA
glucosyl ester. An increase in ABA concentrations in chilled fruit and a decrease in fruit transferred to 20 ◦C has also been reported in the tomato (Ludford and Hillman, 1990). It has been shown that ABA plays a role in stress signal transduction, which is associated
