枣果皮结构与枣裂果性的相关性

Correlation of Fruit Crack and Anatomical Structure in Jujube Fruit

以晋枣、赞皇枣、无名大枣为试材,通过制作石蜡切片,对枣果的上、中、下及其环碗部的解剖结构进行观察和测定,研究枣裂果性与果皮解剖结构的关系。结果表明:枣果皮结构上、中、下各部差异性显著;枣果皮解剖结构与裂果性密切相关,蜡层厚、表皮层数、亚表皮层数、亚表皮厚与裂果指数间相关性不显著,角质层细胞密度、表皮厚度以及环碗部表皮厚度与裂果指数间存在负相关关系。

Jinzao,Zanhuangzao,Wumingdazao were used as test materials,by making paraffin slice,the anatomical structure of fruit peel such as the parts of upper,observing middle and bottom and bowl central division of experiment were observed and measured.The results showed that,there were significant difficence on the upper,middle and bottom of jujube fruit.Fruit cracking and jujube peel anatomical structure had significant correlation,there was no significant correlation between wax thickness,the number of epidermal cell layer,the number of subepidermal cell layer,sub-epidermis thickness and dehiscent fruit index.There were negative correlation between the density of the stratum corneum cells,epidermal thickness and dehiscent fruit index.
