图1. 羊草叶功能性状的差异和变化趋势(平均值±标准误)。LA, 展叶面积; LDMC, 叶干物质含量; LL, 平均叶长; LTL, 总叶长; SLA, 比叶面积; TLM, 总叶质量。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. 1. Dynamics of different leaf functional traits of Leymus chinensis without (CK) and with root-cutting (CR)(mean ± SE). LA, leaf area; LDMC, leaf dry matter fraction; LL, average leaf length; LTL, total leaf length; SLA, specific leaf area; TLM, total leaf mass. y, the quadratic curve fitting equation for CK; Y, the quadratic curve fitting equation for root-cutting. ** and * indicate differences at the 0.01 and 0.05 level, respectively.
