摘要: 研究影响枣裂果的因素对选育抗裂果品种和开发防裂措施具有重要意义。对冬枣 × 临猗梨
枣的F1 子代分离群体进行裂果率和裂果指数测定,并进行石蜡制片和显微观测,探讨同一分离群体的不
同基因型个体间成熟果实表皮结构与裂果的关系。结果显示,48-LS-33,47-LS-22,II-13-15 为极抗裂株
系;抗裂株系比易裂株系果实表皮厚,果实表皮厚度和裂果率呈显著负相关,抗裂类型果实表皮细胞排
列较紧密,角质层沉积导致的表皮第一层细胞垂周状变化明显,而角质层厚度与裂果无明显相关性。

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.

Key words: jujube, fruit cracking, epidermis, cuticle
