表1 不同海拔杜鹃居群环境因子(相对光照强度、温度和相对湿度)的比较(广义线性模型)。不同字母表明同一环境因子在不同海拔居群有显著性差异。加粗表示最大值。

Table 1 Comparison of environmental factors (relative light intensity, temperature and relative humidity) among different altitude populations (generalized linear model, GLM). Different letters indicate significant differences in environmental factors among different altitudes. Bolded numbers indicate maximum values.
