一、材料与方法1.供试材料苦瓜净种子。2.试验设计实验采用了4种不同浸种时间对苦瓜种子催芽,每个处理设4个重复,每个重复50粒种子,以未进行浸种催芽的苦瓜种子作为对照。3.试验方法样品选用随机取样的方法进行取样,每处理200粒种子。处理因素为:浸种温度(55℃的温水)浸种时间:12、24、36、48小时。用具采用高压锅蒸煮30分钟消毒,将种子均匀放置于培养皿内55℃的温水中,在25℃的发芽箱内进行催芽。二、管理与记载 First, materials and methods 1. The test material bitter gourd net seeds. Experiment design experiment used four different seed soaking time to balsam pear seed germination, each treatment set four replicates, each repeated 50 seeds, not to seed soaking germination of bitter gourd seeds as a control. 3. Test Methods Samples were randomly sampled for sampling, for each treatment of 200 seeds. Treatment factors are: Soaking temperature (55 ℃ warm water) Soaking time: 12,24,36,48 hours. Utensils autoclave cooking 30 minutes disinfection, the seeds were evenly placed in 55 ° C Petri dish in warm water, sprouting germination at 25 ℃. Second, management and records
