贵州普定6种喀斯特石生植物及其土壤的碳酸酐酶活性
Carbonic anhydrase activity of six epilithic mosses and their underlying soil in the Puding karst area,Guizhou Province
摘要
Abstract
The samples of six moss plants include B.argenteum,B.unguiculata,E.julaceum,E.leptothollum,R japonicum and T vermicularia were collected from the karst rock desertification area in Puding of Guizhou,as the objects of this study.The carbonic anhydrase (CA) activity of the epilithic plants and the matrix of soil was studied,from which the analyses of bio-karst mechanism and governance of ecological environments in karst rocky desertification areas can be performed.The results show that there are some differ ences in carbonic anhydrase activity of six epilithic plants.The E.leptothollum is highest,reaching 272.99 U · g 1 (FW),while the minimum is 33.45 U · g-1 (FW) in R.japonicum.The B.argenteum base soil CA activity(101.81 U · g 1(dry soil) is the highest.The E.leptothollum is 15.95 U · g-1(dry soils) as the lowest.It could be concluded that CA activity has positive correlations with plant and soil carbonic anhydrase content of total phosphorus,kalium,gravel and soil moisture,respectively.关键词
