水芹雄性不育材料的鉴定及营养品质分析

Identification and nutritional quality analysis of male sterile material of Oenanthe javanica (Blume) DC.

摘要: 水芹（Oenanthe javanica (Blume) DC.）雄性不育材料在水芹杂交育种中具有重要作用。本研究描述了一种雄蕊退化的水芹雄性不育材料（OJBY001）。该材料的特征为：侧枝多、叶片及叶柄深绿色，花丝萎缩和花药干瘪、柱头伸长、能够分泌蜜液及接收外来水芹花粉，隶属于水芹种。相较于可育水芹（OJKY002），OJBY001在茎和叶柄中的干物质极显著高于OJKY002，以及走茎中的维生素C、可溶性糖及类黄酮含量显著或者极显著高于OJKY002中的含量。

Abstract: Male sterility plays an important role in the hybrid breeding of water dropwort (Oenanthe javanica (Blume) DC.). In the current study, a male-sterile water dropwort (OJBY001) with a degenerated stamen was described. OJBY001 was characterized by many lateral branches, dark green leaf blades and petioles, atrophic filaments and anthers, elongated stigma, and the ability to secrete nectar and receive exotic pollen from other water dropwort belonging to O. javanica. Compared to fertile water dropwort (OJKY002), OJBY001 exhibited significantly higher stem and petiole dry matter and and significantly or extremely significantly higher contents of vitamin C, soluble sugar, and flavonoids in the stolon.
