摘　　要：本研究观察了火龙果花朵和果实完整的动态发育过程,测量了其花的长度、宽度和重量等指标以及其果实的纵向直径、横向直径、重量等指标.结果表明本研究建立了夏季火龙果花从冒芽到开花共20天的动态生长曲线,获得了花发育相关指标的动态规律;建立了果实从授粉结束到果实成熟共30天的动态生长曲线,获得了果实发育相关指标的动态规律.本研究结果可为火龙果的杂交育种及火龙果的施肥、灌溉和采收等种植管理提供理论参考.In the report,the dynamic development of pitaya flower and fruit was observed.The length,width and weight of the flower were measured,and the longitudinal diameter,transverse diameter and weight were also measured.A 20-day dynamic growth curve from budding to flowering of pitaya flower and a 30-day dynamic growth curve from pollination to maturation of pitaya fruit in summer were established,and the dynamic law of flower and fruit development related indexes were obtained.Our findings provide the theoretical references for cross-breeding,fertilization,irrigation and harvest of pitaya.
