摘要: |
为明确苦瓜的果实和种子的适宜采收时期,采用“翠中翠”苦瓜为研究对象,对苦瓜果实发育过程中的可溶性蛋白、总可溶性糖、维生素C的含量及种子生活力的变化进行动态监测。结果显示:(1)花后第14天至第26天,随着果实的迅速膨大,可溶性蛋白、总可溶性糖及维生素C含量也迅速增长;(2)种子干物质迅速积累,含水量迅速下降,种子生活力迅速提高,至花后第22天至第26天,种子生活力基本稳定。 |

Abstract: |
In order to determine the proper harvesting stage for fruit and seed of bitter gourd,the study was conducted to monitor the changes in the content of total soluble protein,total soluble sugar,vitamin C and the seed germinability during fruit development. The results showed that:(1)the fruit enlarged rapidity from 14 to 26 days after anthesis(DAA)in coincide with the increase of total soluble protein,total soluble sugar and vitamin C contents;(2)from 14 to 22 DAA,seeds dry matter accumulated in a fast rate associated with the decline of seed moisture content. Seed showed germinability since 14 DAA,and enhanced thereafter,the highest germination percentage was obtained in 22 to 26 DAA. |
