| 摘 要： | 目的]探索新疆野核桃不同小叶数量复叶的生长特征,为野核桃的研究提供基础资料。方法]用米尺大样本测量新疆野核桃3种不同小叶数量复叶及其构件的长和宽,并用电子分析天平称量各构件的生物量。结果]新疆野核桃复叶的长、宽、叶轴生物量和复叶生物量都随复叶的小叶数增加而增大;同叶序小叶的生物量随复叶的小叶数增加而减小。同种复叶的小叶长、宽和生物量随叶序增加而增大。叶柄长和顶小叶长差异不显著;复叶宽差异显著;复叶长、复叶生物量差异极显著。结论]新疆野核桃复叶的大小和生物量均有较大的生态可塑性。

| Abstract: | Objective] The aim was to explore the growth characteristics of different quantity leaflet compound leaves of Juglans cathayensis in Xinjiang so as to provide basic data for the study of J.cathayensis.Method] The length,width and biomass of compound leaves growth characteristics of three types of different quantity leaflet compound leaves of J.cathayensis were measured in large samples.Result] The length,width,rachis biomass and total biomass of compound leaves increased with the number of leaflets increase;leaflets biomass of the same phyllotaxy decreased with the number of leaflets increase.The leaflet length,width and biomass of the same compound leaves increased with the number of phyllotaxy increase.The differences on petiole length and top leaflets length were not significant;there were significant differences on compound leaves width;the differences on the total biomass of compound leaves were extremely significant.Conclusion] There was rather large ecology plasticity of the compound leaves of J.cathayensis in Xinjiang. |
