图1 不同温度处理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 NT和HT分别表示灌浆结实期的常温处理和高温处理; 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; 同一品种中的2个温度处理间相比, 小写字母相同者表示2个温度处理间(NT和HT)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. 1 Differences in SDS-PAGE and relative optical density of storage protein between two temperature treatments NT and HT mean normal temperature regime and high temperature regime during grain filling, respectively. A and B mean SDS-PAGE and relative optical density of storage protein, respectively. For a same rice cultivar, bars indexed with the same small letters are not significantly different (P < 0.05) between NT and HT. Error bars represent SD values of three biological replicates.
