| 摘要 | This paper systematically reviews the mechanisms by which shading influences the accumulation and distribution of plant biomass, leaf morphology and structure, and plant height growth. Generally, plants adapt to low-light environments by modifying their biomass allocation strategies, for example, by reducing the root-to-shoot ratio. The morphology and anatomical structure of leaves exhibit significant responses to shading, typically characterized by an increase in leaf area and specific leaf area, a reduction in leaf thickness, decreased stomatal density, thinning of the palisade tissue, and a lowered ratio of palisade to spongy tissue. These changes serve to optimize the capture and utilization of light energy. Additionally, shading generally promotes an increase in plant height, but the specific response patterns vary depending on the species and their respective shade tolerance thresholds. The paper ultimately emphasizes that future research should integrate multiple environmental factors for long-term observation to more comprehensively elucidate the mechanisms by which plants adapt to the light environment. This approach will provide a theoretical foundation for the practices of understory planting and urban greening. |
