| Abstract: | Exploring the mechanisms underlying jujube fruit cracking is essential for the development of new cultivar with high cracking resistance and also provides important reference to overcome the problem. In this study，the hybrid seedlings between‘Dongzao’and‘Linyi Lizao’were chosen to investigate of the rate of fruit cracking and to reveal the anatomy structure through the paraffin section analysis. Furthermore，the relationship between fruit epidermal structure and fruit cracking susceptibility were analyzed. The results showed that 48-LS-33，47-LS-22，II-13-15 were the genotypes with highest cracking resistance and that there showed a significant negative correlation between the thickness of fruit epidermal cells and cracking rate. The fruit of cracking resistant type had tighter arrangement of epidermis cells than that of cracking sensitive type. The anticlinal changing in first layer epidermis cells caused by cuticle deposition is obvious in the fruit of resistant cracking type，whereas the cuticle thickness was not found to be related to the cracking rate. |
