生长季平茬对柠条单宁含量变化规律的影响
Effects of Cropping During Growing Season on Variation of Tannin Content of Caragana intermedia Kuang et H.C.Fu
摘要
Abstract
Caragana intermedia is a pioneer tree for controlling soil and water loss and degraded sandy grassland,and it is also a good shrub fodder.The content of phenolic substances in Caragana intermedia after cropping in different months of the growing season was determined and the change rule of phenolic substances was analyzed.The results show that in the growing season,the tannin content of Caragana intermedia ranged from 28.1 to 209.7 mg·kg-1,the total polyphenol content ranged from 106.8 to 309.2 mg·kg-1,the simple phenol content ranged from 0.15 to 104.5 mg·kg-1,and the content of condensed tannins varied from 6.94 to 18.31 mg·kg-1.From the overall performance,the contents of the four phenolic compounds were ranked as total polyphenols,tannins,simple phenols and condensed tannins in descending order,and the contents of the four phenolic compounds were higher in March and lower in June.The contents of tannin,condensed tannin and total polyphenol in the whole growing season of Caragana intermedia showed similar trend of wavy pattern.关键词
