Abstract: Dynamic changes of proteins in leaves from different nodes in 6 hybrid seedlings (Jonathan × Golden Delicious) were analyzed with SDS-polyacrylamide gel electrophoresis in apple. Three protein bands were found specific in different phases. The molecular weight of the 3 protein bands were approximately 55 kD, 19 kD and 17 kD. The 55 kD protein presented qualitatively between nodes No.36~75 and No.101~126. The change of 19 kD and 17 kD proteins was found quantitatively. In leaf samples taken below nodes No. 86~100, the content of 19 kD protein was higher, but a sharp decrease occurred in leaves above nodes No.100. The content of 17 kD protein kept high between nodes No. 36~50 and No. 91~105. It is therefore suggested that the 3 proteins were phase change-related in apple seedlings.
