Effects of Exogenous Plant Hormones on Antibacterial Protein Content of Barley

Three plant hormones including GA3,ABA and 6-BA were added respectively during barley steeping.At the end of malting,in GA3-added experimental groups,the content of antibacterial protein was the highest(566.6 μg/g) as the addition level was 0.05 mg/L and the lowest as the addition level was 0.5 mg/L;in ABA-added groups,the content of antibacterial protein was the highest(514.9 μg/g) as the addition level was 20 mg/L and the lowest as the addition level was 40 mg/L;in 6-BA-added groups,the content of antibacterial protein was the highest(484.4 μg/g) as the addition level was 20 mg/L and the lowest as the addition level was 10 mg/L.
