CHEN Qing-Qing,LI De-Zhi

表1 邻株身份(亲缘株、非亲缘株、陌生株)及其与种植密度(高、低)和土壤养分(高、低)交互作用对谷子形态学特征和生物量分配的影响的协方差分析(以茎生物量作为协变量)

Table 1 Analysis of covariance (using stem biomass as a covariate) for the morphology and biomass allocation of Setaria italica in response to neighbor identity (kin, non-kin or stranger neighbors) and its interaction with plant density (high or low) and soil nutrient level (high or low)
