摘要/Abstract

摘要： 以9年生‘红灯’甜樱桃为试材，对果实不同发育时期果肉内源激素变化动态进行了测定分析。结果表明：果肉中ZRs含量在果实第Ⅰ速长期开始时最高，之后除在果实第Ⅱ速长期开始时有小幅增加外，均呈逐渐下降趋势； IAA和GAs的变化动态相似，在果实第Ⅰ速长期含量较高，随果实发育逐渐减少，均在硬核期结束时（盛花后25d）降到最低值，进入第Ⅱ速长期后又迅速增加并达到最大值，与果实生长动态吻合； ABA含量分别在盛花后第5、15、35d出现高峰，与落果（花）时期基本一致。

Abstract: The present experiment, with the sweet cherry (Prunus avium L.) 'Hongdeng' as its cultivar, investigated the dynamic changes of the fruit growth and development as well as the endogenous hormones of the pulp. The results showed that: The content of ZRs in the pulp had the highest values in the beginning of the first fast-developed period (5th day after full bloom), and then had a tendency of decrease with the fruit, grew and developed until maturated.The contents of IAA and GAs in the pulp of young fruit were high in the first fast-developed period(5th -15th day after full bloom), then decreased with its development until the end of the core-harden period (25th day after full bloom), and they all had a tendency of increase in the second fast-developed period (25th -40th day after full bloom) until maturity, corresponding with the fruit growth. The content of ABA had the peak values in the 5th, 15th, 35th day after full bloom, similar to the fruit (flower) dropping periods.
