摘要/Abstract

摘要： 为了了解暗紫贝母对资源变化的适应策略，本研究通过田间控制试验，研究了遮光和施氮对暗紫贝母生物量、生物量分配，以及叶、根C、N状态的影响。结果表明：遮光和施氮处理后，暗紫贝母生物量均减少；遮光下叶片的生物量分配相对增加，叶根生物量比显著升高（P<0.05），但施氮处理下叶根生物量比的变化不明显；遮光和施氮后，暗紫贝母叶、根N含量均显著升高（P<0.05），叶片和根的C：N显著降低（P<0.05）；相关分析显示，叶片N、C：N与暗紫贝母总生物量、叶根生物量比有极显著的相关性（P<0.01）。本研究表明，与生物量分配相比，C-N平衡，尤其是叶片的C：N比能更好的解释暗紫贝母对资源变化的适应。

Abstract: In order to check how Fritillaria unibracteata Hsiao et K.C.Hsia adjusts to resources variation, a controlled field experiment was set, and F.unibracteata's responses of growth and C-N balance to shading and nitrogen addition were examined. F.unibracteata was highly responsive to shading and nitrogen addition. Nitrogen content in leaf and root showed significant increase after shading and nitrogen addition, which induced the decrease of C:N in leaf and root. The ratio of leaf biomass to root biomass(R₁) was significantly increased(P<0.05) under shading treatment, while there was no obvious change of R₁ under nitrogen-addition treatment. Finally, there were significant correlations(P<0.01) between nitrogen content, C:N and total plant biomass, leaf-root biomass ratio. Therefore, C-N balance in F.unibracteata would be a better index of resource strategy.

Key words: Fritillaria unibracteata, shading, nitrogen addition, biomass allocation, C-N balance
