摘　　要：文章对不同繁殖方式、不同生长年限的云南重楼进行了生物量积累和营养分配研究。结果表明,1～8年生云南重楼根茎切段苗、实生苗生物量逐年递增,未有最高峰值。各营养器官折干率和营养分配高低顺序：根茎〉叶〉茎〉须根。根茎干物质积累及全株总生物量积累分为3个生长阶段：缓慢期、增重快速期、增重加速期;叶、茎干物质积累可分为缓慢期、增重快速期、增重平缓期。Biomass accumulation and nutrient aUocation of Paris polyphylla vat. yunnanens/s of different propagating methods and different growth years were studied in the present paper. The results showed that the biomass values of 1 - 8 years Paris polyphylla var. yunnanensis by sexual and asexual propagating methods were increased with the age, without the highest peak. The order of vegetative organs ranked by dry matter content and nutrient partitioning was as follows： rhizome 〉 leaf 〉 stem 〉 root. Biomass accumulations of rhizome and the whole plant could be divided into three stages： slow phase, rapid phase, aeeeleratory phase. Biomass accumulations of leaf and stem could be di-vided into alow phase, rapid phase, steady phase.
