| 摘 要： | 对腾冲过路黄的物候期进行观察，并绘制出物候图谱。测定其各器官生长动态，结果显示：腾冲过路黄的根系集中分布层深度为10～26 cm，其茎含水量平均为82.02％，叶含水量平均为79.87％，根含水量平均为85.68％。采用相关分析及建立生物量一元线性回归方程，茎、叶、根的生物量（干重Y）可分别用Y=0.0213X4.3369、Y=0.0565X3.9657、Y=0.0382X3.517来推测。

| Abstract: | This paper drew out the phenophase spectrogram of Lysimachia tengyuehensis by observation, and measured the growing dynamic of every organ. The results showed that the distribution depth of root system were 10~26cm, and the average water contents of stem, leaf and root were 82.02%, 79.87%and 85.68%respectively. Correlation analysis was adopted to set up unary linear regression equation of biomass. Then the biomass of stem, leaf, root can be conjectured by Y=0.0213X4.3369, Y=0.0565X3.9657, Y=0.0382X3.517 respectively. |
