Analysis on Influence Factors About Determination Amylase Activity of Wheat Seed in Germination

Using iodine-starch colorimetric method to study amylase activity of grain seeds in germination under different temperature,different water temperatures and different germination days.The results showed that at room temperature 20℃,water temperature 40℃,seeds germination 5 days,the amylase activity was the strongest.In a certain range,amylase activity increased with the increasing of room temperature,water temperature and germination days,but saccharify time behaved opposite.
