Abstract
In this paper, the expansion date of onion bulb was divided into three phases by the according as the changes of bulb diameter, changes of soluble protein content and POD (peroxidase) activity in different organs during bulb expansion of different mature yellow onions were primarily studied. The results showed that during the expansion of bulb, for different mature varieties, the expansion of bulb was not synchronous with the increasing of leaf number. As to the same mature varieties, there was a same change trend of soluble protein content and POD activity in different organs such as root, bulb and leaf. There was high content of soluble protein in leaves, whereas, POD activity was high in roots which may be related to mature of onion. The change trends of POD activity in bulb and content of soluble protein in leaves for different varieties were the same, which may be relevance with bulb expansion.
