Namely: each group to prepare six mineral water bottles, respectively, 1,2,3,4,5,6 label, bottom of the bottle have a thin layer of cotton mat. In the 1,2,3,4 release bottle No. 10 seeds have great vitality and a complete dry. 5, put 10 bottles of boiled seeds, 6 bottles of pills 1O put the seeds of destruction of embryos. Bottle No. 1,2,3,5,6, respectively, to watering. 4 bottles of water. No. 1 seed all the bottles of water to drown the other bottle simply wet cotton. No. 3 bottles will be placed in the refrigerator four degrees Celsius, the other bottle incubation temperature of 20 ℃. While cultivating side observation, the teacher asked each leader must do the experiment recorded in this group. Class the previous day as part of a complete soaking the seeds.
