Break Dormancy by Trimming Immature Globba spp.Keywords: embryo rescue , seed dormancy , scarification , Globba seed Abstract: Young Globba winitii seeds at 20 days after pollination were collected and trimmed at different parts of their seed coat, then cultured on MS medium supplemented with 10 mg/l BA, 1.0 mg/l NAA, 10 mg/l GA3 and 30 g/l sucrose. The results showed that the trimming method could break dormancy, and young embryos germinated in the first week. Seeds trimmed down to a naked embryo had the highest germination rate, germination index and speed of emergence, which were 98.03%, 22% and 100%, respectively.
