| 摘 要： | 文中研究了白三叶无性系种群各部分的资源分配。结果表明，水分通过匍匐茎的移动，在母株，幼分枝和老分枝中，水分和氮代谢是整合的。在光、水分和土壤营养充足条件下，新的，幼分枝输入足够的水分和氮，使老分枝和母株促进一个水平。幼分枝的输出并没有降低相互联接的老分枝和母株的生长，根的能值与年龄显著相关，植物体的各部分的能值各异。

| Abstract: | Resource sharing in the different parts of the clonal white clover plant (Trifolium repens L ) was investigated The results showed that the integration of water and nitrogen metabolism occured among parental, young and old branches of a plant when water passed through its stolons Under the sufficient supply of light, water and nutrients from soil, the newly developed branches showed a similar capacity in taking in sufficient water and nitrogen to that of old branches The development of the new branches did not affect the growth of the old and parental branches attached The results also indicated that energy values in roots was significantly related with plant age, however, the energy values were various in the different parts of plant |
