摘 要：
在果实生长发育期,通过测定果实纵径、横径、侧径、体积、鲜重及干重,研究了木瓜杏果实发育规律。结果表明,木瓜杏果实的生长发育动态呈"慢—快—慢—快—慢"的"双S"形曲线,整个发育过程可分为5个时期:幼果缓慢生长期、果实第1次迅速生长期、果实第2次缓慢生长期、果实第2次迅速生长期和果实熟前缓慢生长期。果实第2次缓慢生长期与果实硬核期相吻合,果实第一,二次迅速生长期是果实增长的两个关键时期。果实纵、横、侧径与果实鲜重、体积变化曲线极为相似,并具有同步增长的趋势。

摘 要：
During the growth and development period,through the measure of the vertical diameter,horizontal diameter,side diameter,fruit volume,fresh weight and dry weight of Papaya apricot's fruit,the growth and development of Papaya apricot was studied.The results indicated that the growth and development of Papaya apricot was about double S-shaped curves:slow-fast-slow-fast-slow.The whole growth and development period was divided into five periods:the slow growth period of infant fruit,the first fast growth period of fruit,the second slow growth period of fruit,the second fast growth period of fruit and the third slow growth period of fruit at the beginning of ripening.The second slow growth period of fruit inosculated with the rigidification period of stone,and the first and the second fast growth period of fruit were two pivotal periods for fruit to grow.The variation curves of fresh weight and fruit volume were extremely similar with that of vertical diameter,horizontal diameter,side diameter,and they had the synchronous rising tendency.
