在蔬菜种子检验上常遇到种子发芽困难,发芽试验较难做好的问题。由于蔬菜种类繁多,种子休眠和发芽特性比较复杂,只有深入了解蔬菜种子发芽特性,采用适当的处理,并在发芽时满足这些特性的要求,才能做好蔬菜种子发芽试验,测得正确的发芽率。1蔬菜种子发芽的基本条件1.1水分水分是种子发芽的关键因素。种子必须吸取足够的水分才能使内部的酶或植物激素活化,促进贮藏物质的转化,加强呼吸作用,增加能量供给,促进细胞的生 In the vegetable seed inspection often encountered seed germination difficulties, germination test is difficult to do a good job. Due to the wide variety of vegetables and the complicated dormancy and germination characteristics of seeds, germination tests on vegetable seeds can only be done if they are deeply involved in the germination characteristics of vegetable seeds, proper treatment is adopted, and germination is required to meet these characteristics. The correct germination rate . 1 The basic conditions of germination of vegetable seeds 1.1 Moisture is the key factor in seed germination. Seeds must draw enough water to activate internal enzymes or plant hormones, promote storage material conversion, enhance respiration, increase energy supply, and promote cell growth
