芽库即所有潜在的能进行营养繁殖的芽的集合。芽库和种子库一同构成了植物的繁殖库,在植被的维持和更新中占据着重要地位。根据最新研究进展,从以下几方面归纳了芽库的研究概况:1)芽库与种子库的区别与联系;2)芽库的分类;3)环境因子对芽库建成和动态的影响;4)模型(如矩阵模型、三角函数、马尔可夫(Markov)模型等)在芽库研究中的应用;5)芽库与地上植被的关系。将来应加强不同生态系统的芽库研究、芽库和种子库对地上植被更新的相对贡献以及芽库在植被恢复和重建中的应用。
Bud bank is the aggregation of all buds that can be potentially used for vegetative regeneration. Both bud bank and seed bank compose the propagule bank which plays an important role in vegetation maintenance and recruitment. This paper summarized the research progress on bud bank from the aspects of 1) distinction and relations between bud bank and seed bank,2) classification of bud bank,3) effects of environmental factors on the establishment and dynamics of bud bank,4) applications of theoretic models (e.g.,matrix model,trigonometric function,and Markov model) in bud bank study,and 5) relationships between bud bank and aboveground vegetation. Future researches should pay more attention on the bud banks of different ecosystems,the relative contribution of bud bank and seed bank to the regeneration of aboveground vegetation,and the applications of bud bank in vegetation restoration and reconstruction.
