Young seeds were preserved at 4 ℃ refrigerator with plastic film and inoculated within three days for alleviating the induction tension. The frequency of callus induction of immature embryos was above 95 percent. The frequency of embryonic induction was from 34 percent to 50 percent.

Since the reaction of ABA on scutellum is not sensitive and higher level of ABA can inhibit the plumule and radicle, so that it promotes the scutellum callus growth.

高浓度的脱落酸（ABA）能有效地抑制胚芽和胚根的生长，而对水稻盾片愈伤组织的生长影响较小，从而促进盾片愈伤组织的同步健壮生长。
