研究火龙果果实种子数与单果重的相关性。试验以红肉火龙果为母本，进行自然授粉、自花授粉和异花授粉，并对其果实种子数与单果重的相关性进行分析。结果表明，3种授粉方式果实种子数与单果重均存在线性正相关，回归方程和相关系数分别为y=O．0347x＋84．144、r=O．9428；y=0．0145x＋269．78、r=O．1874；y=0．0477x-7．3009、栅．5617。3种授粉方式果实单果重随种子数量增加而提高。人工授粉是增加果实种子数和提高单果重一项有效的技术措施。

To study relativity between seeds quantity and single fruit weight of Pitaya, red pulp Pitaya （ttylocereus undatus （Weber）Britt.＆Rose）was used as female parent treated witb natural pollination and self-pollination and cross pollination respectively, the relativity analysis results suggest that aver- age single fruit weight is positive correlating to seeds quantity by all three pollination manners with re- gression equation and correlation coefficient of y=0.0347x ＋ 84.144,r=0.gg28;y=0.0145x＋269.78,r= 0.187g;y=0.0477x-7.3009,r=0.5617 respectively. Average single fruit weight is increasing with seeds quantity increased by all three pollination manners. Artificial pollination is an effective way to increase seeds quantity and single fruit weight of Pitaya.
