| 摘 要： | 比较了生长在不同光照强度下的薇甘菊 (Mikainamicrantha) 幼苗的生长型。结果表明 :苗高、节间长、比叶面积、叶面积比、总叶面积、净同化速率、支持结构生物量比、根生物量比和根冠比随着光照强度的变化而改变 ;然而 ,比茎长、比叶柄长、总生物量、相对生长速率和叶片生物量比却保持相对的稳定。说明薇甘菊幼苗对不同的光强梯度具有不同的可塑性和适应性。 |
| 关 键 词： | 薇甘菊 光照强度 形态可塑性 |

| Abstract: | The growth forms of\% Mikania micrantha\% seedlings grown under different light intensity were compared. The results showed that growth forms of the seedlings of \%Mikania micrantha\% changed with light intensities. Under unshading, the shoot length , internodes length, specific leaf area, leaf area ratio, total leaf area and support biomass ratio were significantly lower than those plants under shading, whereas the net assimilation rate, root biomass ratio and root/shoot were higher. While, specific stem length, specific petiole length, total biomass, and relative growth rate and biomass of leaf remained nearly the same. The responses of growth and morphology of \%M. micrantha \%seedlings to different light intensity gradients showed the plasticity and fitness of seedlings. |
| Keywords: | Mikania micrantha \% light intensity morphological plasticity |
