| 摘 要： | 种子大小是一个植物种群间的一个重要性状,具有重要的进化生态学价值。研究表明,攀枝花市几个样地麻疯树种子百粒重干重为45.98 g左右左右(31.15 g~59.15 g),其中壳的绝对投资平均为17.32 g(15.09 g~20.35 g),种仁的绝对投资为20.35(16.06 g~39.91g),种壳相对投资浮动在33%~49%之间(平均值为39%),种仁相对投资浮动在51%~67%(平均值为61%)。种子资源配置样地间差异表明,种子百粒重具有明显的土壤厚度、林木年龄与海拔依赖性。种子大小也对麻疯树种子壳和种仁的资源配置存在显著影响,调节了种仁与种壳的资源配置。结果表明,微地形上种子大小存在明显差异,可能土壤厚度和种子大小对麻疯树种子及其组分资源配置具有主要的调节作用。 |

| Abstract: | The seed size,with an evolutionary and ecological significance,was an important character between plant populations.The 100-seed weight of Jatropha curcas in some plots of Panzhihua City was averagely 45.98 g(varying from 31.15 g to 59.15 g),among them there were averagely absolute allocations of 17.32 g(from 15.09 g to 20.35 g) in the seed shell and was 20.35 g(from 16.06 g to 39.91 g) in the seed kernel,and there were averagely relative allocation varying from 33% to 49%(averaging 39%) in the seed shell a... |
