国家标准GB3543—83《农作物种子检验规程》第4·3节表11的蔬菜作物种子发芽试验技术规定及其附注②所作的说明,明确规定了芹菜、大头菜、雪里蕻、胡萝卜、茴香、莴苣、茄子7种蔬菜种子必须在光照条件下进行发芽试验;而对其余的25种蔬菜种子则表示在黑暗或光照下均可进行发芽试验。为了进一步加以论证和探讨,我们在1987～1988年将这7种蔬菜种子进行了两次光照与黑暗的对比发芽试验。第一次试验于1987年10月24日到11月7日以莴苣、芹菜种子在种子检验室的自然光温(白天20℃左右,晚间15℃左右)条件下进行,其余品种则在发芽试验箱内28℃左右及人工光照,即以箱内两管日光灯(8W)为光源下进行,同时进行黑暗处
National Standard GB3543-83 “Seeds Seed Inspection Regulations” section 4.3 of Table 11 vegetable seed germination test technical regulations and their notes ② instructions made clear that the celery, kohlrabi, shrimps, carrots, fennel, lettuce, eggplant Seven kinds of vegetable seeds must be germinated under light conditions; while the remaining 25 kinds of vegetable seeds are said to germinate in the dark or light. In order to further demonstrate and explore, we conducted two light and dark contrast germination tests on the seven kinds of vegetable seeds from 1987 to 1988. The first experiment was carried out on October 24, 1987 to November 7, 1987 with lettuce and celery seeds in the seed laboratory temperature of natural light (about 20 ℃ during the day and night about 15 ℃) under the conditions of the remaining varieties in the germination test chamber Within about 28 ℃ and artificial light, that is, two tubes fluorescent lamp (8W) as the light source, while the dark place
