蔬菜种子的新与陈,直接影响种子的发芽率,现介绍简便的识别方法:1.甘蓝、萝卜等十字花科的蔬菜种子:先看种皮,再压种仁.新种子表皮光滑,富有光泽,有清香气味,用指压种仁有油分,碎后成片状,种皮脱离,子叶浅黄或黄绿色.而陈种子表皮无光泽,贮藏不好表皮有“盐霜”,闻之有“哈喇”味,用指压子叶易碎,种皮易脱离,子叶黄色,油分少.2.菜豆等豆类种子:新种子子叶绿色.富油分,有香味,口咬有涩味,而陈种子子对深黄,或有上黄色斑纹,无清香味.3 南瓜、黄瓜等瓜类种子:新种子富有光泽呈乳白或白色,富含油分有香
Vegetable seeds new and Chen, a direct impact on the germination rate of the seed, is now introduced to facilitate the identification of: 1. Cabbage, radish and other cruciferous vegetable seeds: first look at the seed coat, and then pressure seeds. The new seed smooth skin, rich Luster, aroma smell, with finger pressure seeds have oil, broken into flake, seed coat detached, cotyledons light yellow or yellow-green .And Chen seed sub-surface dull, poorly stored epidermis, “salt cream” “Ha La” taste, with finger pressure cotyledon fragile, easily separated from the seed coat, cotyledons yellow, less oil. 2. Beans and other bean seeds: new seed cotyledons green. Rich oil, aroma, biting astringency, and Chen Seeds on the dark yellow, or yellow markings, no fragrance .3 pumpkin, cucumber and other melon seeds: New seed is shiny white or white, rich in oil with aroma
