图2 不同施氮水平下水稻籽粒贮藏蛋白SDS-PAGE及其主要蛋白条带的相对光密度差异 LN、MN和HN分别表示低氮(0 kg hm-2)、中氮(180 kg hm-2)和高氮(300 kg hm-2)处理水平; A和B分别表示水稻籽粒贮藏蛋白SDS-PAGE图和主要蛋白条带的相对光密度图; 相同水稻品种, 小写字母相同者表示不同氮处理水平间的差异未达到统计显著水平(P < 0.05); 垂直棒代表3次生物学重复的标准误差。

Fig. 2 Differences in SDS-PAGE and relative optical density of storage protein among three N treatments LN, MN, and HN mean low nitrogen (0 kg hm-2), medium nitrogen (180 kg hm-2), and high nitrogen (300 kg hm-2) levels, respectively. A and B mean SDS-PAGE and relative optical density of storage protein, respectively. Bars indexed with the same small letters are not significantly different (P < 0.05) between different N levels for the same rice cultivar; Error bars represented SD values of three biological replicates.
