蔬菜作物的种子与其他农作物一样,发芽需要一定的温度、湿度、光照、氧气等环境条件。不同种类的蔬菜,其发芽所需的条件各异,发芽指标主要取决于生物学特性。根据国内外学者的研究成果证明,种子休眠就其生理特性综合起来,由两方面的原因引起。一方面是与种胚或胚乳有关的内因;另一方面是与种皮或果皮有关的外因。在细胞质中积累了一些种子发芽的抑制物质,诸如氢氰酸,多种氨基酸和芳香化合物等,这些物质对于种子的萌发,起到了阻碍 Vegetable crops and other crops, like seeds, germination requires a certain temperature, humidity, light, oxygen and other environmental conditions. Different types of vegetables, the germination of the conditions required for different indicators of germination depends mainly on biological characteristics. According to the research results of scholars at home and abroad, it is proved that the physiological characteristics of seed dormancy can be summed up by two reasons. On the one hand, the internal cause associated with the embryo or endosperm; on the other hand, the external cause associated with the seed coat or peel. In the cytoplasm accumulated some seed germination inhibitory substances, such as hydrocyanic acid, a variety of amino acids and aromatic compounds, these substances for seed germination, hinder
