图2 糯稻不同产量等级群体的叶面积指数动态 HY: 高产; HRY: 更高产; SHY: 超高产; N-n: 有效分蘖临界叶龄期; J: 拔节期; H: 抽穗期; MK: 乳熟期; W: 蜡熟期; M: 成熟期。不同大、小写字母分别表示在P < 0.01和P < 0.05水平差异显著。

Fig. 2 Dynamic changes of leaf area index at different yield levels in glutinous rice HY: high-yield; HRY: higher-yield; SHY: super high-yield; N-n: critical leaf-age for productive tillers; J: jointing; H: heading; MK: milky stage; W: waxy stage; M: maturity. Different uppercase and lowercase letters indicate significant differences at the 0.01 and 0.05 levels, respectively.
