摘要/Abstract

摘要：

探究不同季节毛榛(Corylus mandshurica) “小枝系统” (老枝、新枝和叶)的生活策略差异可为野生毛榛的保护和管理提供理论基础, 同时促进对植物多器官联动响应气候变化的理解。该研究以阔叶红松林中灌木层优势种——毛榛为例, 在春(5月)、夏(7月)和秋(9月) 3个季节分别测量了毛榛老枝、新枝和叶的碳、氮、磷、可溶性糖、淀粉、总非结构性碳水化合物、总酚、单宁和类黄酮含量9个性状。结果表明: 除器官对淀粉含量的影响不显著外, 季节、器官及其交互作用对毛榛功能性状均具有较显著的影响。老枝在春季和夏季时, 总酚和单宁含量较高, 秋季时可溶性糖含量较高; 新枝在春季时氮含量较高, 而夏季和秋季时, 其总非结构性碳水化合物、单宁和类黄酮含量较高; 叶在春季和夏季时氮和磷含量较高, 而秋季时类黄酮含量较高。另外, 在春季和夏季, 叶相比新枝和老枝, 其性状相关性网络更复杂; 在秋季时则相反。这反映在毛榛“小枝系统”中, 春季时, 叶和新枝趋向“生长”策略, 老枝趋向“防御”策略; 在夏季时, 叶趋向“生长”策略, 而新枝和老枝趋向“防御”策略。在秋季时, 叶趋向“防御”策略, 新枝和老枝趋向“资源回收”策略。研究结果揭示了毛榛“小枝系统”的生长与防御策略存在差异, 这有利于促进关于植物如何响应环境变化的理论研究向系统化和精细化的方向发展。

Abstract:

Aims Exploring the differences in the life strategies of the “twig system” (old twig, new twig and leaf) of Corylus mandshurica in different seasons can provide a theoretical basis for the protection and management of wild C. mandshurica. At the same time, it can promote the understanding of the multi-organ coordinated response of plants to climate change.

Methods In this study, taking the dominant species in the shrub layer of the broad-leaved Korean pine forest, C. mandshurica, as an example, nine traits including carbon, nitrogen, phosphorus, soluble sugar, starch, total non-structural carbohydrates, total phenol, tannin and flavonoid contents in the old twigs, new twigs and leaves of C. mandshurica were measured in three seasons, namely spring (May), summer (July) and autumn (September).

Important findings The results showed that, except that the effect of the organ on starch was not significant, the season, the organ and their interaction had a relatively significant effect on the functional traits of C. mandshurica. In spring and summer, the contents of total phenol and tannin in the old twigs were relatively high, while in autumn, the contents of soluble sugars and other substances were relatively high. In spring, the nitrogen content in the new twigs was relatively high, while in summer and autumn, the contents of total non-structural carbon, tannin, flavonoid and other substances in the new twigs were relatively high. In spring and summer, the nitrogen and phosphorus contents in the leaves were relatively high, while in autumn, the contents of flavonoid and other substances in the leaves were relatively high. In addition, in spring and summer, compared with the new twigs and old twigs, the trait correlation network of the leaves was more complex; in autumn, the situation was the opposite. This reflects that in the “twig system” (old twig, new twig and leaf) of C. mandshurica, in spring, the leaves and new twigs tend to adopt a “growth” strategy, and the old twigs tend to adopt a “defense” strategy; in summer, the leaves tend to adopt a “growth” strategy, while the new twigs and old twigs tend to adopt a “defense” strategy. In autumn, the leaves tend to adopt a “defense” strategy, and the new twigs and old twigs tend to adopt a “resource recycling” strategy. The research results reveal that there are differences in the growth and defense strategies of the “twig system” of C. mandshurica, which is conducive to promoting the theoretical research on how plants respond to environmental changes towards the direction of systematization and refinement.
