图4 渍水锻炼对花后渍水胁迫下小麦干物质积累与转运的影响 RAP: 花前贮藏物质转运量; REP: 花前贮藏物质转运率; CTA: 花前贮藏物质对籽粒贡献率; PAA: 花后光合同化量。不同字母表示品种内处理间在P < 0.05水平差异显著。品种信息同表2。处理同图1。

Fig. 4 Effects of waterlogging priming on dry matter accumulation and translocation under post-anthesis waterlogging stress in wheat RAP: remobilization amount of pre-anthesis stored dry matter; REP: remobilization efficiency of pre-anthesis stored dry matter; CTA: contribution of pre-anthesis stored dry matter; PAA: post-anthesis photosynthetic assimilates accumulation. Different lowercase letters indicate significant differences at P < 0.05 among different treatments of each variety. Varieties are as the same as in Table 2. Treatments are the same as those given in Fig. 1.
