图3 糯稻不同产量等级群体的光合势动态 HY: 高产; HRY: 更高产; SHY: 超高产。(N-n)-J: 有效分蘖临界叶龄期至拔节期; J-H: 拔节期至抽穗期; H-MK: 抽穗期至乳熟期; MK-W: 乳熟期至蜡熟期; W-M: 蜡熟期至成熟期。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. 3 Dynamic changes of leaf area duration at different yield levels in glutinous rice HY: high-yield; HRY: higher-yield; SHY: super high-yield. (N-n)-J: from critical leaf-age for productive tillers to jointing; J-H: from jointing to heading; H-MK: from heading to milky stage; MK-W: from milky stage to waxy stage; W-M: from waxy stage to maturity. Different uppercase and lowercase letters indicate significant differences at the 0.01 and 0.05 levels, respectively.
