Exogenous application of IAA and ABA on FHB progression on barley treated heads and its effects on seed grain yields and quality. (a) Percentage of infected spikelets following IAA and ABA pre-Fusarium treatment. (b) A 1000 grain weight determined for the untretad water control (C) and the corrisponding pathogen exposed-IAA and ABA and the no-treatment head (C+P). (c) Fusarium head blight effects on barley heads for untreated control (C+P), IAA, ABA as compared to unexposed control (C). (d) Fusarium head blight effects on barley kernels. Treatment codes: C, controls treated with Tween20; C+P, controls treated with Tween20 plus pathogen (F. culmorum); IAA, indole-3-acetic acid; ABA, abscisic acid. Bars indicate standard error of mean.
