葡萄果实组织结构与耐贮性的关系

The Relationship between Fruit Texture and Storage Character in Grapes

通过对‘巨峰’、‘红地球’、‘秋红’、‘秋黑’葡萄果实解剖结构和超微结构的比较,探讨葡萄果实品种间耐贮性差异的生理学原因。结果表明:葡萄的耐贮性与果皮和果肉的组织结构有密切关系。耐贮性好的品种其角质层及表皮组织均比较厚,表皮细胞排列整齐而致密,且与亚表皮细胞的结合紧密,其果肉组织排列也比较紧密,且果肉细胞大小均匀。不同葡萄品种之间,表面蜡质超微结构相差很大,蜡质层较厚、蜡质分布均匀而致密的品种对SO2抗性较强;相反,蜡质层薄、蜡质排列疏松、蜡层之间空隙较大的品种对SO2较为敏感。

Is this paper, the comparison of anatomic structure and ultra-structure were studied in ＇ Kyoho＇ , ＇ Red Globe＇ , ＇ Autumn Black＇ and ＇ Autumn Red＇ grapes to inquire the physiology cause of diversity storability in different grape fruits. The result showed that storability of grapes and percarp and fruit texture has close relationship. The good storage property varieties have thicker horny layer and cuticle texture, cuticle cell orderliness and compact, even combined closely with sub-cuticle cell, the fruit tissue arranged the fruit cells well-distributed. Wax ultra-structure in fruit outer covering has large diversity closely and in different grapes. The grape have thick wax surface, even distribution wax, compactly and regularly arranged pericarp cells resist SO2 stronger. That have thin wax surface and arranged relax and have large gap in wax layer cells were sensitive to SO2.
