以亮叶无蜡质紫色芥蓝突变型紫.中花芥蓝和多蜡质紫色芥蓝野生型为试材,对芥蓝叶片发育过程中最外层的表面蜡质进行系统地观察,并对无蜡质突变型紫.中花芥蓝、多蜡质野生型芥蓝和普通绿色芥蓝(CK)的干物质量、VC、可溶性糖、粗纤维、蛋白质、花青苷等主要营养成分含量进行测定分析。结果表明:在叶片发育过程中,多蜡质野生型芥蓝的叶面蜡质明显多于无蜡质突变型紫.中花芥蓝;野生型芥蓝和紫.中花芥蓝叶片背面的蜡质均明显多于叶片腹面;野生型芥蓝叶片背面的蜡质退化速度明显慢于叶片腹面。无蜡质突变型紫.中花芥蓝的VC含量高于野生型芥蓝,而粗纤维(DW)含量低于野生型芥蓝,说明紫.中花芥蓝有利于改良现有芥蓝的营养品质,有望育成高VC含量、高花青苷含量、以生食为主的芥蓝品种。芥蓝叶片的无蜡质性状对多蜡质表现为隐性遗传,紫色对绿色表现为显性遗传。
The waxy purple non-waxy purple khaki mutant purple, C. korshinskii and multi-wax purple kale blue were used as materials to systematically observe the outer wax surface of kale during the leaf development The contents of major nutrients (VC, soluble sugar, crude fiber, protein, anthocyanin, etc.) of non-waxy mutants purple Chinese flowering Chinese kale, waxy wild type kale and common green Chinese kale (CK) Analysis of the measurement. The results showed that during the development of leaves, the leaf wax content of the multi-wax wild type kale was significantly higher than that of the non-waxy mutant purple. Wax content was significantly higher than the ventral surface of leaves; Wax degradation rate of the back of wild-type kale leaves was significantly slower than the ventral leaves. Wax-free mutant purple.The content of VC in Chinese kale was higher than that of wild kale but the content of crude fiber (DW) was lower than that of wild kale, Nutritional quality, is expected to bred high VC content, high anthocyanin content, raw kale varieties. The non-waxy traits of kale leaves showed recessive inheritance for multi-waxy, while purple showed dominant inheritance for green.
