The contents of cellulose, lignin and activities of POD, PAL in excised bamboo shoots of Phy llostachysedu lis were studied. The result showed that in excised bamboo shoots from top part to base part, the contents ofcellulose and lignin increased gradually, while the activities of POD and PAL on top part of shootwasmore than thatof base part. Along with p rolongation of the storage time, the contents of cellulose and lignin increase rap idly. Inthe first 5 days cellulose increase rap idly, in the second 5 days it becomes to slow down apparently. But the lignincontent increased in a even speed during the storage time. At the same time the activities of POD and PAL increasedsignificantly with the storage time. Bamboo shoots treated by low temperature (4 ℃) showed that low temperaturecould decrease the activities of POD and PAL significantly, aswell as decrease the contents of cellulose and ligninsignificantly. The influence of low temperature for cellulose was bigger than that for lignin.

Abstract: The contents of cellulose, lignin and activities of POD, PAL in excised bamboo shoots of Phy llostachysedu lis were studied. The result showed that in excised bamboo shoots from top part to base part, the contents ofcellulose and lignin increased gradually, while the activities of POD and PAL on top part of shootwasmore than thatof base part. Along with p rolongation of the storage time, the contents of cellulose and lignin increase rap idly. Inthe first 5 days cellulose increase rap idly, in the second 5 days it becomes to slow down apparently. But the lignincontent increased in a even speed during the storage time. At the same time the activities of POD and PAL increasedsignificantly with the storage time. Bamboo shoots treated by low temperature (4 ℃) showed that low temperaturecould decrease the activities of POD and PAL significantly, aswell as decrease the contents of cellulose and ligninsignificantly. The influence of low temperature for cellulose was bigger than that for lignin.
