摘要
本研究采用Logistic生长模型和幂函数曲线方程分别对青蒿株高生长和分枝特性进行了曲线方程拟合,并对株高生长与分枝数目变化进行了比较分析。结果表明:曲线方程拟合度分别为0.922和0.998,能较好地反映青蒿株高生长与分枝特性,为青蒿高产栽培和良种选育提供参考。
The equations were configured for characteristics of branching and plant growth, and the relationships between them were analyzed. The results indicated that the characteristics of plant growth and branching conformed to the Logistic model and power function model curve model, with the R^2 values of the curvilinear equations were 0. 992 and 0. 998, respectively. They were suitable for describing the characteristics of plant growth and branching, providing reference for high-yield cultivation and breeding of Artemisia annua.
