The results showed that the levels of free-form ABA-like inhibitors in flower buds were very high at the onset of dormancy, and then sharply decreased within two weeks. This trend was seen in all cultivars. After two weeks dormancy, the level of inhibitors fluctuated until the last four weeks before the termination of dormancy, thereafter the level rapidly decreased. This was seen in Floridabella and Ang Khang White. However in the Ventura peach the inhibitors levels decreased about six weeks before flowering and increased again in the last two weeks. No relationship was found between the inhibitor levels in the flower buds and the dormancy period of the three peach cultivars. The TNC content in the shoots was high at the first period of dormancy, and sharply decreased thereafter which correspond to the decrease in the level of inhibitor in flower buds. Similar pattern of changing in that dormant period was seen in the reducing sugars contents. Thereafter the reducing sugar content gradually increased until flowering. However, no relationship was found between the level of free-form ABA in the flower buds, the contents of reducing sugars and TNC in the remaining shoot and the dormancy period of flower buds in these three peach cultivars.
