Effects of exogenous abscisic acid and gibberellic acid on pre-maturity α-amylase formation in wheat grains

Effects of in situ and in vitro applied abscisic acid (ABA) and gibberellic acid (GA3) on pre-maturity α-amylase (PMA) were investigated in glasshouse experiments under cool-temperature shock-induced and non-induced conditions using UK winter wheat varieties, Spark (low PMA susceptible) and Rialto (high PMA susceptible). In the in situ study, hormone solutions (ABA [100 μM], GA3 [50 μM] and ABA + GA3 [100 + 50 μM]) were applied during mid-grain...
