摘　　要：通过对云南丽江、昆明和个旧的云南松(Pinus yunnanensis Franch．)松脂分泌量的测定揭示,云南松泌脂量因地 域而有明显差异,泌脂量多少与所在纬度的高低存在负相关。在同一地点,云南松泌脂量随坡向不同而异。一般地 说,北坡的松脂流量略小于南坡的松脂流量。同一树体的不同方位的松脂流量并无明显差异。就同一树木不同高度 而言,在大树的中下部,泌脂量随取样高度增加而增大。分析认为,温度可能是影响云南松泌脂量变化的重要因素。Based on the resin flow measurement of Pinus yunnanensis trees growing on three localities, Lijiang, Kunming and Gejiu of Yunnan Province, it recovered that the resin flow exhibited significantly differences among the three localities. It was suggested that resin flow amounts were negatively related to the degree of latitude. In the same measuring locality, the resin flow was related to the slope orientation. Generally, the resin flow of the trees growing at the northern slope was smaller than that at the southern slope. No significances had been discovered for the resin flow among different orientations of the same tree. In general, the resin flow of the trunk increased with the trunk height. However, the present study did not measure the resin flow inside the crown of the tree.
