Review of research methods of soil seed bank
摘要
Abstract
Soil seed bank (SSB) includes all living seeds existing in both litter and soil. Studies on SSB has important guiding significance for better understanding the past aboveground vegetation communities and predicting the future vegetation communities development, while studies on methods of SSB provide foundation and support for basic experimental research. In this paper, we summarized the research SSB methods from the SSB sampling time, sampling methods, sample size and the number of statistical methods in four areas, the application of stable isotope in the seed age structure of the SSB, and the research method of canopy seed bank, and the new method in improving SSB germination rate. Our comprehensive analysis were as follows:(1)Four key issues on soil including seed bank sampling time, sampling methods, sample size and number of identification methods of SSB research methods needed to be focused on, which had a significant direct impact on the experimental results of SSB. Different sampling time represented the content of the SSB, and significance of different sampling methods should be based on the size and number of research areas, and research on determining the specific identification method should be based on the number of species studied experimental area to consider;(2)the application of isotope in the seed age structure of the SSB in theory was feasible, but it needed further study in experiment; (3)current canopy seed bank research methods was confined to direct counting method and indirect counting method, the research methods on the canopy seed bank needed to be improved; (4)four methods in improving seed germination of SSB were summarized and presented people should pay attention to and strengthen the application of these four kinds of methods to measure SSB in using seed germination in the future.关键词
