Abstract: During the course of plant tissue culture, Camptotheca acuminata leaf explants were observed on anatomy characteristics. We found that cell wall of C. acuminata leaves presented anatomy characteristic of weakly degrading, obviously degrading, totally degrading and cell wall disappearance under tissue culture conditions. Cell wall of identical C. acuminata leaf exhibited distinct properties in their degree of degradation and even disappearing at the same condition of tissue culture. It may be the upper epidermis protruding to influence different contacts position with culture medium and make acid material of culture medium to cause different position of C. acuminata leaf explants to appear heterogeneity.

Key words: tissue culture, cell wall, acid degradation
