| 摘 要： | 对重庆市仙女山昆明山海棠从种子雨及土壤种子库动态进行了研究。结果表明,昆明山海棠的成熟种子年内分布数量以10月最多,种子雨散落从9月下旬到11上旬,散落高峰期集中在10月份,千粒重最重期、生活力最高期也出现在10月份。土壤种子库以距灌丛中心2~5 m分布最多,主要集中在1.5~3.5 m。土壤种子库主要分布枯枝落叶层,种子寿命较短。昆明山海棠种子以风为外力进行传播,其传播能力较强,但在自然繁衍过程,成熟饱满种子率较低、土壤种子库种子种子寿命不长等因素严重影响昆明山海棠种群更新。

| Abstract: | Tripterygium hypoglaucum is an endangered species in arid areas of Xiannvshan Chongqing, China. The dynamic characteristics of seed rain and soil seed bank of T. hypoglaucum were studied in this paper.Results showed that T. hypoglaucum years of mature seeds distribution number up to October;the seed rain occurred from the last ten-day of September to in the first ten-day of November and the peak of scattered seed rain concentrated in the October.The numbers of soil seed bank at 2-5 cm soil layer,mainly concentrated in the 1.5-3.5 m range. T. hypoglaucum seeds to the wind as a force for transmission, the transmission ability is strong, but in the process of natural reproduction, full mature seed rate is low, the soil seed bank seeds seed short-lived factors these were unfavorable for the natural reproduction of T. hypoglaucum population. |
