摘要: 本研究通过采用不同光质培养与幼苗叶绿素测定的方法,对红皮、黄皮和白皮三个类型的洋葱种子进行了快速鉴定技术研究,结果表明,在适宜的暗培养条件下,肉眼可鉴定白皮洋葱与有色洋葱种子,对有色的红皮与黄皮洋葱种子进行鉴定具有局限性。叶绿素测定,暗培养条件下三种类型的洋葱种子未见显著差异。可见光下,叶绿素含量在三种类型的洋葱种子中存在显著差异,可以利用叶绿素含量鉴定区分。肉眼观测未见可识别的颜色变化。

Abstract: Under different light treatment and chlorophyll testing, seed of three onion varieties could be rapidly identified. There is a significantly different of seedling color betweent unpigmented and pigmented onion seedling by naked eye under black germination condition, the seedling color of red and yellow onion almost looks same, there are no significantly different of Chlorophyll contains. Pigmented onion seedling has significant high Chlorophyll contains than unpigmented under visible light germination condition, but it looks same by naked eye, no color different between each onion seedling.
