植物叶片养分再吸收特征及其影响因子
|
摘要
收集国内公开发表的有关植物叶片养分再吸收的相关文献,从中提取叶片氮(N)和磷(P)再吸收效率(RE)、N和P含量及环境因子等数据,对植物叶片养分再吸收特征及其影响因子进行系统分析.结果表明:N和P再吸收效率分别与衰老叶中对应养分含量存在显著负相关关系,表明养分再吸收效率越高再吸收程度也越高.N、P再吸收效率的差值与成熟叶N/P呈显著负相关,表明植物在生长过程中会加强对限制性元素的选择再吸收.叶片N再吸收效率随纬度增加而增加,与年均气温(MAT)、年均降雨量(MAP)呈负相关关系,而P再吸收效率与三者的相关性并不显著.不同生活型植被P再吸收效率无显著差异,固氮植物N再吸收效率显著低于除藤本以外的非固氮植物,乔木、灌木、草本、藤本间N再吸收效率无显著差异.本文对叶片养分再吸收效率与环境、生物影响因子的探讨证实了"相对再吸收假说"(植物生长过程当受到某种元素限制时会对该元素具有较高的再吸收效率).
Nutrient resorption plays a key role in nutrient conservation in plants, especially in nutrient-deficient environments. However, little is known about the characteristics of nutrient resorption at a large scale domestically. This study was aimed at investigating the relationships between nutrient resorption and regional factors. We collected published data on leaf N and P concentrations and mean annual temperature(MAT) and precipitation(MAP). We classified the data according to the habit and plant form, and analyzed the correlations among the variables. Our results showed that there was a significant negative correlation between N and P resorption efficiency and the corresponding nutrient concentrations in senescent leaves. The difference between N and P resorption efficiency and N/P ratio of mature leaves had a significant negative correlation, indicating that plants would increase the absorption of restrictive elements during growth. N resorption efficiency increased with latitude, and correlated negatively with MAT, as well as MAP. However, P resorption efficiency did not correlate with these factors. There was no significant difference in P resorption efficiency of among the different plant forms. The N resorption efficiency of nitrogen-fixing plants was significantly lower than that of non-nitrogen-fixing plants except lianas; however, no significant difference was observed among other life forms. Furthermore, this study confirmed the "relative resorption hypothesis" through the discussion on nutrient resorption in leaves and environment and biological factors. The specific conclusion is that plants would have higher absorption efficiency for certain elements, which is limited during plant growth.
