| 摘 要： | 从构件入手，研究了生长季羊草种群根茎，营养枝和生殖枝及其构件的生物量和能量分配及季芤动态，结果表明种群营养枝和生殖枝的生物量和能量分配没有显著的颉抗关系，但营养枝和根茎生物量和能量分配比较间呈显著的颉抗关系，研究结果还表明种群根茎，营养枝和生殖枝及构件的生物量和能量分配比例间的差异基本不显著，而且季节动态趋势一致，即生物量分配和能量分配是等价的。

| Abstract: | The biomass and energy allocation among the rhizome, vegetative shoot, reproductive shoot and population modulus of Leymus chinensis were studied by using modulus analysis. The results show that there was not trade-off between vegetative shoot biomass/energy and reproductive shoot bimass/energy, but there was trade-off between rhizome biomass/energy and vegetative shoot biomass/energy. The results also show that there was not significant different between the rate of biomass allocation and the rate of energy allocation, and the two rates similar enough that one could be substituted for the other. |
