摘  要：
以桃品种"双红艳"、短枝"双红艳"为试材,"大久保"为对照,采用0~7.2℃模型对桃品种需冷量进行了研究,并用体视显微镜检测花芽纵横径发育状况。结果表明:"双红艳"与短枝"双红艳"的需冷量为1 000~1 200h,"大久保"需冷量为800~1 000h;取样期间花芽纵横径一直在增加,至休眠结束前达到最大,花芽各器官发育完全,花瓣原基、花药和花柱原基都已经形成。

摘  要：
‘Shuanghongyan'and spur‘Shuanghongyan'peach were used as test materials,‘Okubo'peach as control.0-7.2℃ model were used to study the chilling requirement.Longitudinal and traverse diameter of blossom bud were detected by stereoscopic microscope.The results showed that the chilling requirement was differet among peach cultivars.The chilling requirement of‘Shuanghongyan'and spur‘Shuanghongyan'were both 1 000-1 200 hours,while ‘Okubo'was 800-1 000 hours.Longitudinal and traverse diameters of blossom bud at different stages were also enlarged and reached the maximum.The petal,stamen and pistil primordium had formed before the end of dormancy.
