| The objectives of this work was to determine the germination traits of Pugionium cornutum(L.) Gaertn seeds. The results indicate: 1. The optimum germination temperature of P.cornutum seeds was 25℃～27℃ ,it can germinate under 13℃or 38℃ ,but the germination rate was very low and impractical; 2. The seed absorbed water rapidly in the first stage, seed moisture content can get to 35%～40%(g/g dry seed) after previous 80min of soak and the effects of different temperature(15℃,25℃and35℃) was not significant. However, the temperature effects became significant with the soaking time lasting. When the soaking time get to 10h there were significant differences among the seed moisture content which ranged 60% to 75% under different temperature (35℃<15℃<25℃,αï¼0.05). 3. The seeds are sensitive to light and hardly to germinate under 24h light treat. 4. The germination of P.cornutum seeds were repressed significantly by 40～60mg/L GA3,but the effects of 5～30mg/L GA3,25～50mg/LKT,25～50mg/L BA and 25～50mg/L NAA were not significant. 5. The seed moisture content decrease and the germination rate increase during storage after harvesting. The highest germination rate emerged 100d after harvesting. Comparing to covered seeds, the germination speed of seeds that were peeled was lowered. 6. The storage lipid,protein and starch content are 51.22%,12.89% and 5.22%, all the storage matters decrease during germination. |
