| Abstract: |
| 【Objective】In order to break the dormancy and shorten the breeding period, the seeds of Curcuma alismatifolia‘Spring’×C. alismatifolia‘Scarlet’were soaked under different treatments.【Method】The experiment was conducted by using three treating methods including hormones, hot water and their combination. The soaking time and hormone concentration were different for each group. All the seeds were pregerminated for two months by using filter paper method at 28 ℃ . The germination potential and germination rate of the control group（clean water）and experimental group were investigated.【Result】Compared with the control group, the seeds of experimental groups were germinated one month in advance by using hormones and hot water treatment. It was found that the germination potential and germination rate exhibited highest values of 29.3% and 50.7% respectively under 400 mg/L GA3 treatment. Hot water soaking for five minutes at 80 ℃ reached an optimal effect, with the germination potential and germination rate of 10.3% and 17%, respectively. However, part of the seeds suffered death from scald. Moreover, it was regarded as the perfect solution through combining hot water soaking for 10 minutes at 60 ℃ with 400 mg/L GA3 treatment for 24 h. The germination potential was 40.7% and the germination rate was up to 64.3% after sowing two months.【Conclusion】The effects of combination of hormones and hot water treatment were significantly better than other treatments for the seeds germination of C. alismatifolia. This method was suitable to be applied in breeding practices due to its guarantee of early germination and uniform seedling. |
