| 摘 要： | 研究了江西三清山天女花种子的特性,结果表明:(1)三清山天女花种群种子雨自10月初开始,10月末结束,10月中旬强度达高峰,玉京峰地段天女花种子雨持续时间较短;(2)产种率受母树冠层影响,即上层>中层>下层;种子败育率高(49.4%～100.0%);(3)主成分分析表明,乔木层盖度、大气湿度、光照因子以及土壤含水量对天女花种子发育产生显著影响。

| Abstract: | Seed characteristics of Magnolia sieboldii in Sanqing Mountain were studied.The results showed that: 1) The seed of M.sieboldii in Sanqing Mountain began to fall early October,and stopped the end of October.The intensity of M.sieboldii seed rain reached a peak in mid-October.The time of M.sieboldii seeds falling in Yujing Peak was shorter than that in Sanqing Temple.2) The seed production rate of M.sieboldii was affected by the parent canopy,with the upper > middle > lower.And the seed abortion rate of M.sieboldii was higher,between 49.4%～100%.3) Principal component analysis showed that the tree layer cover,atmospheric humidity,soil moisture and light factor all have a significant impact on the seed development of M.sieboldii in Sanqing Mountain. |
