细叶百合生物量的生殖分配

对野生环境中多年生球根类植物细叶百合（Lilium pumilum DC.)进行了生物量生殖分配季节动态研究，各构件在不同季节生物量分配的平均值从大到小的顺序为：鳞茎＞茎＞叶＞生殖构件；从蕾期至花期生殖构件生殖生物量分配增加近44倍，两性结构与雄蕊、雌蕊的生殖生物量比为9：5：1；不同季节生殖构件生物量分配与地下构件生物量呈负相关，与地上非生殖构件生物量分配呈正相关。

Biomass Reproductive Allocation of Lilium pumilum

Through studying biomass reproductive allocation and seasonal dynamic state of perennial cormogenous plant Lilium pumilum which lives in the wild environment, the result indicated that the average biomass allocation of building block in different seasons decreased in the order: bulb>stem>leaf>reproductive building block; reproductive biomass allocation of reproductive building block increased about 44 times from bud to anthesis, and the ratio of reproductive biomass of bisexual structure to stamen and pistil is 9:5:1; there is negative correlation between biomass allocations of reproductive building block in different seasons and underground building block; there is positive correlation between biomass allocations of reproductive building block and ground non-reproductive building block.
