图3. 羊草茎功能性状的差异及变化趋势(平均值±标准误)。SDMC, 茎干物质含量; SL, 茎长; SLWR, 茎长/茎粗; SW, 茎粗。y, 二次曲线拟合方程(对照); Y, 二次曲线拟合方程(切根)。**、*表示分别在0.01、0.05水平上差异显著(双尾检测)。
Fig. 3. Dynamics of different stem functional traits of Leymus chinensis (mean ± SE). SDMC, stem dry matter fraction; SL, stem length; SLWR, stem length/stem diameter; SW, stem diameter. y, the quadratic curve fitting equation for control (CK); Y, the quadratic curve fitting equation for root-cutting (CR). ** and * indicate differences at the 0.01 and 0.05 level, respectively.
