| 摘 要： | 目的]分析厚皮甜瓜腔内种子的生长发育规律,为提高厚皮甜瓜制种产量和质量提供参考依据.方法]以具有腔内种子发芽特性的厚皮甜瓜自交系05-6为试验材料,分析授粉后果实腔内种子的生长发育规律、腔内种子发芽的发生时期和变化趋势,比较不同授粉天数果实腔内种子的饱满程度、数量、发芽率、成苗率和幼苗健壮程度差异.结果]厚皮甜瓜腔内种子成熟时间比果实成熟时间早,授粉后第26 d种子已充分饱满.其中,未发芽种子的饱满度、数量、发芽和成苗能力及成苗的健壮程度与授粉后第35 d(即果实完全成熟时)相比差异不显著(P>0.05);已发芽种子数量显著少于授粉后第35 d腔内发芽种子数量(P<0.05).结论]提前摘瓜采种是降低厚皮甜瓜腔内种子发芽率的有效措施,厚皮甜瓜材料05-6的适宜采种时间为授粉后第26 d.

| Abstract: | Objective]The study were carried out to investigate growth and developmental regulation of intracavity seeds in muskmelon,and provide reference for improving seed production yield and quality.Method]The experiments used inbred line 05-6 whose seeds germinated in fruit as material. Seeds growth and development in fruit after pollination, occurrence time and change trend of intracavity seeds germination were analyzed. Differences of seeds plumpness,germi-nated seed number,germination rate, survival seedlings rate,robustness level of seedlings in different days after pollina-tion were compared.Result]The maturity of intracavity seeds was earlier than muskmelon fruits. On day 26 after pollina-tion,seeds were fully matured. In terms of the ungerminated seeds, compared with seeds on day 35 after pollination(when the fruit were completely mature),there were no significant(P>0.05)differences in seeds plumpness,number, germination ability,survival seedlings ability,robustness level of seedling. By contrary,the number of germinated seeds was signifi-cantly fewer than that in fruit on 35 d after pollination(P<0.05).Conclusion]Picking up fruit and collecting seeds in ad-vance before fruits is matured fully is effective strategy for reducing seeds germination rate in fruit,and the most suitable picking time was day 26 after pollination for muskmelon 05-6. |
