不同郁闭度对野外回归的梓叶槭幼树形态和生理特征的影响

濒危植物野外回归是扩大极小种群野生植物种群的有效途径。适宜的回归生境是物种生长的必要条件, 研究植物的生理生态特征对不同野外回归生境的适应性, 是科学评价濒危物种种群回归生境适宜性的关键指标。本文以野外回归的极小种群野生植物梓叶槭(Acer catalpifolium)为研究对象, 探讨了无遮荫、林缘、林隙以及林下(郁闭度由小到大) 4种不同光照条件对梓叶槭幼树的形态特征、光合特征、类黄酮指数及叶绿素含量等的影响。

Ex situ field reintroduction of endangered plants is an effective approach to expanding the populations of wild plant species with extremely small populations (PSESP). A suitable reintroduction habitat is a necessary prerequisite for the growth of plant species. Investigating the adaptability of plants' physiological and ecological characteristics to different field reintroduction habitats is a key indicator for scientifically evaluating the habitat suitability of endangered plant populations. Taking the reintroduced wild plant species with extremely small populations, Acer catalpifolium, as the research subject, this study explored the effects of four distinct light conditions (no shading, forest edge, forest gap, and understory, with canopy density increasing from low to high) on the morphological traits, photosynthetic characteristics, flavonoid index, and chlorophyll content of Acer catalpifolium saplings.
