摘要
探讨了广西桂林岩溶石山阴香幼苗的形态因子和生物量的生长动态,并运用数理统计学理论建立了它们与苗龄之间的回归方程。结果表明,随着苗龄的增加,阴香幼苗的形态因子和器官生物量均不断增大,但在不同时期它们的增长速率不同;幼苗的株高与苗龄之间符合二次曲线模型,基径与苗龄之间符合三次曲线模型,而叶面积以及器官生物量与苗龄之间符合线性模型。
The growth dynamics of morphological characters and biomass of Cinnamomum burmannii seedlings on the karst hills in Guilin, Guangxi were analyzed, and the regression equation between the morphological or biomass parameters and seedling age was set up by the method of statistics. The results showed that the morphological parameters of seedlings and organ biomass were increased with the growth of seedlings, but they had different increasing rates during different growth phases. The relationship between height and age fitted the quadratic models, the relationship between diameter and age fitted the cubic models, and the relationship between leaf area or biomass and age fitted the linear models.
