Abstract:
Responses of sugar metabolism during germination of soybean(Glycine max)seeds to simulated acid rain(pH 2.0,2.5,3.0,3.5,4.0,4.5,5.0)were investigated.The purpose was to clarify the mechanism of acid rain affecting seed germination.The α-amylase,amylase activity and the content of soluble sugar,reducing sugar,sucrose and starch decreased to the lowest under pH2.0.The contents of the four types of sugars increased with the decreased stress level of acid rain.The response of amylase to acid rain stress is stronger than α-amylase.Results suggest that soybean could adapt to acid stress by adjusting sugar metabolism level during germination period.
