摘要

[目的] 掌握植物地下芽库多样性及形成的环境机制，为保护和恢复生物多样性提供理论依据。[方法] 以若尔盖高原湿地的沼泽、沼泽化草甸和草甸3种生境为对象，运用单因素方差分析、相关性分析以及通径分析等对试验数据进行处理。[结果] ①芽库密度表现为沼泽>沼泽化草甸>草甸，生境间差异显著。沼泽以水平生长的根茎顶芽为主，沼泽化草甸和草甸则分别以根茎节芽和分蘖节芽为主。②芽的长度表现为沼泽>沼泽化草甸>草甸，生境间差异显著。沼泽和沼泽化草甸的芽的直径均显著高于草甸，但沼泽和沼泽化草甸间无显著差异。沼泽的芽长/直径比值和生物量均显著高于沼泽化草甸和草甸，但沼泽化草甸和草甸间无显著差异。③芽的全氮含量（TNB）也表现为沼泽>沼泽化草甸>草甸，且均差异显著，三者的全磷含量及芽氮磷比值无显著差异。[结论] 在若尔盖高原，土壤水分、速效氮和全磷是解释芽库密度、芽形态（长度、直径）、芽生物量，以及芽生态化学计量的主控因子。

Abstract

[Objective] The diversity of belowground bud banks and their underlying environmental determinants were studied in order to provide important theoretical value for protecting and restoring biodiversity.[Methods] Three habitats such as marsh (MA)

marsh meadow (MM)

and meadow (ME) in the Zoige Plateau wetland were selected as the study object

and the experimental data were processed by single-factor analysis of variance

correlation analysis

and path analysis.[Results] ① The total density of the belowground bud bank in MA was the largest

followed by those of MM and ME. Among the habitats

significant differences were recorded. Bud banks in MA were dominated by horizontal apical rhizome buds

while the bud banks in MM and ME were dominated by axillary rhizome buds and shoot buds

respectively. ② The bud length of MA was much larger than that in MM and ME

and the differences between these habitats were significant. The bud diameters of MA and MM were much larger than that in ME

while no significant difference was recorded between MA and MM. The bud length/diameter in MA was significantly larger than those in MM and ME

while there was no significant difference recorded between MM and ME. ③ The total nitrogen content of belowground bud (TNB) in MA was much larger than that in MM and ME

and a significant difference between habitats was found. However

no significant differences were recorded between the habitats for both total phosphorus content of bud (TPB) and the TNB/TPB ratio.[Conclusion] Soil moisture

available nitrogen

and total phosphorus were the main factors controlling density

morphology (length and diameter)

biomass

and ecological stoichiometry of belowground buds on the Zoige Plateau.
