| 摘 要： | 为研究人工授粉和自然授粉2种授粉方式红肉火龙果果实生长动态规律，对授粉第5天后的果实进行纵横径测定，以后每隔5天测定一次，直至果实成熟；再计算果实纵横径、体积及净生（增）长并对2种授粉方式果实的生长动态曲线进行比较。结果表明，2种授粉方法果实纵横径在授粉后5~10天生长较快，出现最大的净生长；人工授粉纵横径生长在同一时期比自然授粉快；人工授粉果实体积呈现“快-慢-快”的双“S”形增长动态曲线，而自然授粉体积增长只呈现“快-慢”的“S”形增长动态曲线；人工授粉果实体积在着色至采收期间仍保持较快生长。因此在授粉后的前期（5~10天）和后期（20~25天）应加强肥水管理，促进果实纵横径和体积较大的净生（增）长。试验结果对探讨火龙果果实生长发育规律，为火龙果授粉、水肥管理、采收等生产措施提供理论依据和参考。

| Abstract: | To survey dynamic growth of fruit in Hyloeereus polyrhizus which were treated by hand pollination and natural pollination respectively, horizontal and vertical diameter of fruit were detected each five days from the fifth day after pollination to ripen. Horizontal and vertical diameter, volume and net growth weight were recorded. Comparing curves of dynamic growth of fruit in two treatments, we found that horizontal and vertical diameter increased rapidly in the 5-10 days after pollination in both treatments while the biggest net growth weight occurred at the same time, yet horizontal and vertical diameter in hand pollination group was higher than natural pollinations. Horizontal and vertical diameter increment curve in hand pollination treatment turned out to be double ＂S＂ shape while single ＂S＂ in natural pollinations. Volume increment kept fast during fruit coloration stage to harvesting stage. To insure bigger net fruit increment, we should enhance fertilizer and water management in initial stage （5-10 days） and late stage （20-25 days） after pollination, .Hand pollination in Hyloeereus polyrhizus may raise yield as well as increasing the fruit quality. We explored the rule of dynamic growth of fruit in Hyloeereus polyrhizus which may provide theoretical foundation for practical measures such as pollination, water and fertilization management and harvesting as well as provide reference for relevant research. |
