To analyze the development of reproductive organs and initial fruit set, the pattern of bud burst and flowering, morphology of flower organs, development of embryo sac, and fruit set were investigated by using lowand mid-chill peach and nectarine cultivars in the northern highlands of Thailand. The observation was carried out at Angkhang (19°45' North, 99°10' East, 1400m elevation) and Khunwang (18°40' North, 98°40' East, 1300m elevation) Research Stations within the framework of the Royal Project Foundation in Chiang Mai Province. From mid-November, the decrease of the minimum daily temperature was larger in Angkhang than in Khunwang. By early March, 450 Richardson Chilling Units (CU) had accumulated in Angkhang, whereas no CU accumulation was recorded in Khunwang. In Angkhang, flower bud burst of the low-chill cultivars started in early November and the final percentage reached about 70%. Flower bud burst in Khunwang occurred earlier than in Angkhang, but the bursting rate remained below 40% even in the low-chill cultivars. Although the rate of leaf bud burst was very high at both locations, the leaf bud burst was considerably delayed in Khunwang. The flowers in Khunwang were significantly smaller than those in Angkhang. The development of the embryo sac was also less satisfactory in Khunwang than in Angkhang. The low percentage of flower bud burst and inadequate development of the reproductive organs may account for the low fruit set rate in Khunwang.
