为了培育早熟桃或油桃,常常需采用果实发育期短的品种作为母本。然而这些品种的种子发芽率低,胚发育不完全,萌发不良。本研究的目的拟用几种化学药剂处理早熟桃和油桃某些品种的植株及果实,通过延迟果实脱落为胚成熟赢得更多时间,或加速胚的发育来提高其种子的发芽力。试验结果表明,于第一次批量采收前25～30天(即果实 In order to cultivate precocious peach or nectarine, it is often necessary to adopt varieties with short fruit development periods as the female parent. However, the seed germination rate of these varieties is low, incomplete embryo development, poor germination. The purpose of this study is to use several chemical agents to treat plants and fruits of some varieties of precocious peach and nectarine, and to increase their seed germination by delaying the fruit shedding into embryo maturation to gain more time or accelerate embryo development. The test results showed that 25-30 days before the first batch harvest (ie fruit
