图2 SDC和NSC叶面积指数对中后期氮胁迫的响应(2017) Nn: 正常施氮处理; Ns: 氮胁迫处理。误差线为标准差。图中数据为同一施氮水平下的同一类3个品种的平均值。其他缩写同表1。

Fig. 2 Leaf area index (LAI) of SDC and NSC in response to nitrogen stress at mid-later growth stage (2017) Nn: Normal nitrogen application; Ns: Nitrogen stress treatment. The error bar is standard deviation. The data in the figure are the average values of three cultivars in the same category under the same nitrogen application level. Other abbreviations are the same as those given in Table 1.
