摘　　要：通过对金沙江干热河谷地区滇榄仁花生物生态学特性观察、种子性状检测和不同季节播种育苗试验及容器苗培育结果表明,滇榄仁在干热河谷的“集中开花模式”,是其适应干热河谷环境,达到生殖成功的需要,但也是导致其种子饱满度低、败育率高的重要原因。滇榄仁种子春播和秋播育苗的成苗率分别为11.2%和10.9%,已基本能够满足现有条件下生产性育苗的需要;春播种子苗木4月苗龄苗高可达到秋播种子苗木9月苗龄苗高的81.6%,春播更适合滇榄仁苗木的生产性培育。According to the observation of floral biological and ecological characteristics,seed character detection,sowing and seedling raising experiments of Terminalia franchetii in different seasons and container seedling cultivation results in the dry-hot valley of Jinsha river,the results indicated that the“intensively blooming pattern”of Terminalia franchetii in the dry-hot valley is necessary for its adaptation to the dry-hot valley environment to achieve reproductive success,but it was also an important reason for its low seed plumpness and high abortion rate.The seedling establishment rate of Terminalia franchetii in spring and autumn was 11.2% and 10.9% respectively,which were basically sufficient for productive seedlings under existing conditions.The 4-month-old seedling height of spring sowing seed seedling could reach 81.6%of the 9-month-old seedling height of autumn sown seed seedlings,which indicating that spring sowing was more suitable for productive cultivation of Terminalia franchetii seedlings.
