  • The activities of phenylalanine ammonia lyase (PAL) and peroxidase (PO) and contents of cellulose and lignin in new digging bamboo shoot of phyllostachys pubescens and P. prominens were measured. The PAL and PO activities were progressively reduced from shoot base to top. contents of cellulose and lignin decreased from base to top. Bamboo shoots were placed at 25 ℃ for 4 day in room. The changes in PAL and PO activity and in cellulose and lignin contents were studied. The results indicated that the activities in PAL and PO and contents in cellulose and lignin increased by a big margin, and the course of lignification was moved forward from shoot base to top. Lignification resulted in loss of edibility.
