| 摘 要： | 以黑龙江 657( HL657)、意大利 7号 ( Italy7)、大曹杏和实生 1 9号杏品种为试材 ,对各品种不同结果枝类型以及不同树冠部位的杏花败育率调查 ,并在休眠、萌芽、花蕾期喷 GA3 、乙烯利 ,统计各品种杏花雌蕊败育率及花粉活力情况。结果显示 :杏花雌蕊败育率与品种有很大关系 ,杏栽培品种长果枝败育率最高 ,中果枝次之 ,短果枝最低 ;树冠上部杏花败育率较树冠中部及下部低 ;GA3 处理增加了杏花败育率 ,并使花粉活力提高 ;乙烯利处理可促使杏花雌蕊败育率降低 ,但同时也降低了花粉活力

| Abstract: | In this paper, four apricot varieties, Heilongjiang 657 (HL657), Italy No. 7, Dacaoxing and Shisheng No. 19 were employed as experimental objects to investigate the flower abortion of different apricot varieties. At different set fruit shoots and different crown parts, and statistics of apricot pitil abortion and fresh pollen vitality was collected after sprayed with GA 3 and ethylene during dormant, sprout and bud periods. It has been discovered that variety selection has a great bearing on apricot pistil abortion among cultivated varieties, long fruit shoots were the highest, medium ones lower and short ones the lowest: abortion on the top of the crown was much lower than on its medium and lower parts, and abortion and fresh pollen vitality were increased by GA 3 treatment and decreased by ethylene treatment. |
