Abstract:

To investigate the reason of seed dormancy and the methods of relieving the seed dormancy in Aconitum flavum, Using the TTC method to determinate the seed activity of Aconitum flavum, while using the running water washing the seed, the different stratification treatment, and the GA soaking the seed to determine them the influence on seed germination, in addition detecting the inhibitory activity of extract of the seed in Aconitum flavum on the seed in cabbage and Aconitum flavum. The seed viability of Aconitum flavum up to 90%, Seed bibulous reach saturated with 14 h, and seed coat permeability was good. When the extracts concentration of seed kernel was 0.8 g/mL, the seed germination rate in cabbage was only 38.3%. It was indicating that the seed contains the endogenous inhibitor. The method of running water washing can be partially to remove the inhibitors and improve the germination rate. The low temperature and poikilothermic stratification treatment can effectively break the dormancy of seed, especially in low temperature stratification, the germination rate of seed up to 79.67%. 200μg/mL GA3 with 24 h treatment on seed was best for germination, and the germination rate can be to 82%.
