摘　　要：对生长季不同月份红松不同部位单宁的含量进行了研究。红松当年生叶和宿生叶单宁含量呈稳步上升的规律,韧皮部单宁含量呈有波动的上升趋势,木质部单宁含量与叶类似呈稳步上升的规律,均在9月份达到最大;枯落叶单宁含量未呈现明显规律,各月份之间差异不大;红松各部分单宁含量为韧皮部>老叶>当年叶>木质部。Tannin in different parts of korean pine in growing season is studied in this paper .Tan-nin in new leaves ,old leaves and xylem showed steady rising ,tannin in phloem showed fluctuant rising ,and reach the peak of the year in September ;Tannin in litter didn’t showed obvious rule ;Tannin contents in different parts are phloem 〉old leaves〉 new leaves〉xylem .
