花卉产品质量的检测种子①发芽势、发芽率。a.检测仪器。电热恒温培养箱、光照发芽器及其他发芽设备,体视显微镜或手持放大镜,滤纸,吸水纸,培养皿,镊子等。b.检测方法。测定发芽势或发芽率时,每次至少测定200粒种子,经净度分析后,从充分混合的净种子中随机抽取,每重复100粒或少于100粒的若干重复。根据不同种子的特性确定适宜的培养温度及光照强度。待种子发芽后,每天检查和记载出芽的种子数,达
Flower product quality testing Seeds ① germination potential, germination rate. a. Test equipment. Electric incubator, light germination and other germination equipment, stereomicroscope or hand-held magnifying glass, filter paper, absorbent paper, Petri dishes, tweezers and so on. b. test method. Determination of germination potential or germination rate, at least 200 seeds were measured each time, after the clarity analysis, from the net seed mixed fully selected, each repeated 100 or less than 100 of a number of repeats. According to the characteristics of different seeds to determine the appropriate culture temperature and light intensity. After the seeds germinate, check and record the number of germinated seeds daily
