Spraying 6-BA could alleviate the harmful impacts of waterlogging on dry matter accumulation and grain yield of wheat

Figure 1. Rainfall in 10-days of each month during the whole wheat season at Jingzhou weather station from 1983 to 2012. (Values of each month is the means from 1983 to 2012) Figure 2. Monthly average temperature and total rainfall during wheat growing seasons at experimental station from 2011 to 2012 (A) and 2012 to 2013 (B) cycles. Figure 3. The effect of different treatments on the aboveground biomass production at maturity of 2011 to 2012 (A) and 2012 to 2013 (B) cycles. Figure 4. The effect of different treatments on photosynthetic rate of flag leaf after booting stage of 2011 to 2012 (A) and 2012 to 2013 (B) cycles. Figure 5. The effect of different treatments on MDA content in flag leaf (A, C) and the third leaf (B,D) at 25 DAA (2011-2012 and 2012-2013). Figure 6. The effect of different treatments on the root activities at 0-20 cm soil layers after booting stage.Table 1. Wheat major growth stages in the two growing seasons. Dates are mean values of treatments.Table 2. Effect of different treatments on grain yield, kernel number per spike and 1000 kernel weight.
