Nested mixed-model Ancova for growth-related traits of Trifolium montanum, Ranunculus bulbosus and Briza media grown under ambient and elevated temperature.

d.f., degrees of freedom; MS, mean squares; F, F-values; Initial plant size, covariate; Temp, temperature treatment; Orig, altitude of population origin; Pop, population. Residual d.f. vary per trait due to missingness. Bonferroni-corrected significance levels within species are indicated by asterisks: ***PBonf PBonf PBonf PBonfd.f.为自由度（degrees of freedom）；MS为均方（mean squares）；F为F值（F-values）；初始植株大小为协变量（covariate）；Temp指温度处理（temperature treatment）；Orig指种群起源海拔（altitude of population origin）；Pop指种群（population）。不同性状的残差自由度因数据缺失情况存在差异。物种内经邦费罗尼校正的显著性水平以星号标注：***PBonf PBonf PBonf PBonf
