了解树种如何调节多种类型的次生化学物质沿着海拔梯度是至关重要的阐明植物的生理和生态策略，以应对不同的生物和/或非生物环境。本研究旨在探讨乌桕（Triadica sebifera）如何分配资源，以生产不同的次生化学物质，以应对不同的环境跨越海拔梯度。
我们在中国沿沿着海拔梯度对乌桕树进行了不同植食性昆虫取食团及其危害率的野外调查，并测定了受害和未受害叶片中次生化学物质（单宁和黄酮）的含量。
叶子受损（咀嚼或结疤）的几率随着海拔的升高而降低。黄酮类化合物浓度随海拔升高而增加，但在受损的叶片，槲皮苷的海拔高度下降，这种模式的贡献最强烈，可能是植物响应变化的生物或非生物应力的结果沿着海拔梯度。单宁浓度不随海拔而变化，所以未受损的叶子有相对较低的单宁黄酮比例在高海拔比低海拔。我们的研究揭示了食草动物的变化和对比的趋势，植物次生代谢沿着海拔梯度，并强调了同时考虑多种类型的次生化学物质在植物生理和生态策略的重要性。
Understanding how tree species regulate multiple types of secondary chemicals along elevational gradients is critical for elucidating the physiological and ecological strategies of plants in response to varying biotic and/or abiotic environments. This study aims to examine how Chinese tallow tree (Triadica sebifera) allocates resources to the production of different secondary chemicals in response to varying environments across elevational gradients.
We conducted field surveys of different herbivore feeding guilds and their damage rates on Chinese tallow trees along an elevational gradient in China and measured secondary chemicals (tannins and flavonoids) in damaged and undamaged leaves.
The odds of a leaf being damaged (chewing or scarring) decreased with elevation. Flavonoid concentrations increased with elevation in undamaged leaves but decreased with elevation in damaged leaves, with quercitrin contributing most strongly to this pattern, likely as results of plant responding to changing biotic or abiotic stresses along elevational gradients. Tannin concentrations did not vary with elevation, so undamaged leaves had relatively lower tannin to flavonoid ratios at high elevation than at low elevation. Our study reveals variation in herbivory and contrasting trends in plant secondary metabolism along an elevation gradient and highlights the importance of simultaneously considering multiple types of secondary chemicals in plant physiological and ecological strategies.
