图3 温氮处理下水稻籽粒贮藏蛋白的SDS-PAGE及其主要蛋白条带的相对光密度差异 LN和HN分别表示高氮和低氮水平; NT、HT1和HT2分别表示常温处理(日均温度23℃)、高温I处理(日均温度30℃)和高温II处理(日均温度34℃)。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。小写字母相同者表示不同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. 3 Differences in SDS-PAGE and relative optical density of storage protein treated under different temperature regimes and different N levels LN and HN mean low nitrogen and high nitrogen levels, respectively; NT, HT1, and HT2 mean normal temperature regime (23℃), HT1 (30℃) and HT2 (34℃), 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) among different treatments; Error bars represent SD values of three biological replicates.
