中文摘要：

以采自云南、贵州、四川13个不同地域滇重楼地理种源为研究对象,在同一种质资源圃条件下,对其叶片碳氮代谢关键生理生化指标进行了比较研究。结果表明：13个滇重楼地理种源叶片碳氮代谢相关生理生化指标种源间差异显著,但各指标变化规律不一致。滇西北种源碳代谢能力较强;云龙种源碳代谢最为旺盛,氮代谢处于中等水平;永善种源氮代谢较为旺盛,碳代谢处于中等水平。从碳氮代谢平衡角度考虑,云龙种源和永善种源为较优滇重楼种源。叶片碳代谢有随着纬度增加、温度和年降水降低而增加的趋势。

英文摘要：

The compared study on key physiological and biochemical indices of C,N metabolism of 13 geographical strains of Paris polyphylla var. yunnanensis taken from different provinces and geographical regions were carried out under the same planting condition. The result showed that there were significant difference of key physiological and biochemical indices among 13 geographical strains,but the change rule were not coordination,and there were vigorous C metabolism in northwestern region of Yunnan Province. Yunlong strain had high vigorous C metabolism and middle N metabolism,while Yongshan strain had vigorous N metabolism and middle C metabolism. From the point of view of C,N metabolic balance,Yunlong and Yongshan strain were better than others. There were increasing tendency of C metabolism strength with increased latitude and with decreased annual temperature and annual rainfall.
