Abstract:
The contents of proteins and the compound of vegetative storage proteins in the bark, xylem and roots during the course of sprouting of the one-year-old poplar clone 797 have been measured and analyzed by SDS-PAGE. The results indicated that the content of proteins in the bark, xylem and root decreased obviously during the course of sprouting. The vegetative storage proteins mainly stored in the bark and xylem in winter, the contents in the root were relatively low at that time. The proteins such as 36kD, 32kD, 18kD, 16kD and etc. changed greatly during the course of the poplar shoots sprouting, of which the proteins 36kD, 32kD could be recognized clearly before sprouting and disappeared gradually 4 weeks after the leaves spreading, while the proteins 18kD, 16kD could be found only during the leaves growing and disappeared completely afterwards. The proteins 36kD, 32kD were probably the main types of vegetative storage proteins of poplar.
