| 摘 要： | 以红肉火龙果（Hylocereus polyrhizus）的果实为材料，对火龙果的果实和种子的产量性状进行考察，研究果实产量性状与种子产量性状的相关关系，探索火龙果的产量形成机制。对火龙果果实按照大小分组取样，对火龙果的种子产量性状和果实产量性状进行统计及相关性分析。结果表明:单个火龙果的种子数量、种子质量与火龙果的果实质量高度相关；火龙果果实的横径、纵径与果实质量高度相关；火龙果的种子百粒重(质量)与果实质量、果实横径、果实纵径的相关不显著。因此，在火龙果栽培中，采取合适的栽培管理措施，增加果实中的种子数量，有利于提高火龙果的果实产量。

| Abstract: | In order to explore the fruit yield formation mechanism of pitaya, taking red-flesh pitaya（Hylocereus polyrhizus） fruit as experimental material, the fruit yield traits and seed yield traits of pitaya were investigated, the correlation between fruit yield traits and seed yield traits was studied. The results showed that the seed number and seed weight of single pitaya fruits were highly correlated with the single fruit weight of pitaya; The transverse diameter and longitudinal diameter of pitaya fruit are highly correlated with single fruit weight. The 100-seed weight had no significant correlation with single fruit weight, transverse diameter and longitudinal diameter. Therefore, it is beneficial to improve the fruit yield of pitaya by adopting appropriate cultivation and management measures to increase the seed number in pitaya fruit. |
