以色列伏尔加尼亚热带园艺、农业研究中心报道,对果实发育时产生乙烯阳油梨落果进行了调查。油梨坐果后不久便开始自然落果(5月),除7月末落果率短暂升高外,直到9月,落果逐渐减少。0.2克重的小果落果率每周达30％以上,较大的果落果率每周在1％以下;9月后,当果实生长衰退,种皮开始皱缩时,落果停止。发现小果的坐果率和果实的落果率与乙烯的产量呈正相关。种子残缺的小果产生的乙烯比正常的果实高6—9倍。残缺种

Israel’s Volgaña Tropical Horticulture, Agricultural Research Center reported that the fruits of the development of ethylene decadent pear was investigated. The pears started to fall naturally shortly after fruit setting (May). In addition to a brief rise in the fall rate at the end of July, fruit drop gradually declined until September. 0.2 grams of small fruit fall rate of more than 30% per week, the larger fruit falling rate of less than 1% per week; September, when the fruit recession, the seed coat began to shrink, the drop stopped. It was found that the fruit setting rate and the fruit drop rate were positively correlated with the ethylene yield. The small seeds of the seed produce 6 to 9 times more ethylene than normal fruits.
