摘要

濒临灭绝的尼尔森绢云杉(Serianthes nelsonii)的恢复工作一直很不顺利。为了进一步了解叶片的生长成本,研究人员测定了在不同入射光下生长的叶片的支撑组织和叶片组织中生物量和必需元素的含量。在透光率为 22% 的条件下,叶片所需的生物量是全日照条件下的 65%,光照处理并不影响支撑组织和叶片组织之间的平衡。在阳光充足的叶片中,碳、磷、铁、锰和硼的浓度最高,而在遮光的叶片中,氮、钾、钙、镁和锌的浓度最高。在支持组织中,碳、氮、钾、钙、镁和锌也表现出与光照相同的模式。与此相反,遮光叶片的支持组织磷含量最高,而光照水平并不影响其余元素在支持组织中的浓度。除了钾和镍在支撑组织中含量较高外,叶片中的其他元素含量始终较高。这些结果表明,全日照下的尼尔森蓟马叶片比遮光叶片的构建成本更高,而支撑组织和叶片组织之间生物量和必需元素的转移并不受发育光照水平的实质性影响。确定尼尔森树叶元素浓度的驱动因素对于了解这种魅力树种在群落级过程中的作用至关重要。

Incident Light Level Influences Elemental Budgets of Serianthes nelsonii Merr. Leaf Development
Recovery efforts for the endangered Serianthes nelsonii have been deficient. To learn more about leaf development costs, the content of biomass and essential elements were determined in the supportive and laminae tissue of leaves that were constructed under different levels of incident light. The biomass required to construct a leaf in 22% light transmission was 65% of that in full sun, and light treatment did not influence the balance between supportive and laminae tissues. Concentrations of carbon, phosphorus, iron, manganese, and boron were greatest for in full-sun laminae, but those of nitrogen, potassium, calcium, magnesium, and zinc were greatest in shaded laminae. The same patterns with regard to light were exhibited in supportive tissues for carbon, nitrogen, potassium, calcium, magnesium, and zinc. In contrast, the supportive tissue phosphorus content was greatest in shaded leaves, and the light level did not influence the supportive tissue concentrations of the remaining elements. The leaf laminae consistently exhibited greater concentrations of elements with the exception of potassium and nickel, which were greater in the supportive tissues. These results indicate that the construction of full-sun S. nelsonii leaves is more costly than that of shaded leaves, and the transfer of biomass and essential elements between the supportive and laminae tissues is not substantially influenced by the developmental light level. Identifying the drivers of S. nelsonii leaf element concentrations is crucial for understanding the role of this charismatic tree in community-level processes.
