摘要

以腾格里沙漠东南缘人工固沙植被区藓类结皮优势种真藓(Bryum argenteum)和土生对齿藓(Didymodon vinealis)为研究对象,在野外条件下设置4个降雪处理,分别是无降雪(对照)、1/2降雪、1倍降雪、2倍降雪,降雪后测定植株光合色素含量、脯氨酸含量、可溶性糖含量、可溶性蛋白含量以及丙二醛(MDA)含量,研究结皮层2种藓类植物对降雪的生理生态响应及其差异性。结果表明:随降雪量增加,真藓和土生对齿藓光合色素含量和可溶性蛋白含量均升高,且土生对齿藓含量上升趋势更明显;随降雪量增加,2物种脯氨酸含量、可溶性糖含量及丙二醛(MDA)含量均降低,且土生对齿藓可溶性糖含量与MDA含量下降趋势更明显。冬季降雪能够对结皮层藓类植物光合作用和生理活性起到一定促进作用;土生对齿藓对降雪的响应更明显。降雪量增加可能会改变藓类结皮层物种组成和结构,并对维持荒漠生态系统健康产生重要影响。

Abstract

In this study, Bryum argenteum and Didymodon vinealis crusts were sampled from an artificial vegetation area of southeastern fringe of the Tengger Desert in northwestern China (37°32'-37°26'N,105°02'-104°30'E). Four snowfall treatments were applied: non-snowfall (control, 0S), half of the ambient conditions (0.5S), ambient snow (S), and double ambient conditions (2S). A series of important physiological index were measured after a snowfall event, including photosynthetic pigment content, proline content, water-soluble sugar content, water-soluble protein content and malondialdehyde (MDA) content, to study the effects of snowfall on physiological and ecological characteristics of the two mosses and the differences between them. The results showed that with an increase in snowfall, the content of photosynthetic pigment and water-soluble protein increased, while the content of proline, water-soluble sugar and MDA decreased. Moreover, the change of physiological index following snowfall was greater in D. vinealis than that in B. argenteum. These results suggested that winter snowfall enchanced the photosynthesis and physiological performance of B. argenteum and D. vinealis, and D. vinealis was more sensitive to snowfall than B. argenteum. This study indicated that D. vinealis could be more competitive under increasing snowfall, and the structure and function of BSCs in desert ecosystem will improve, and has theoretical significance in maintaining the health and stability of desert ecosystem.
