Abstract: The experiment was mainly observed and compared on the effect of different chemical priming treatments and soaking time to the Solanum Torvum seed germination,used 500~2000mg/L GA3,0.5%~5.0% KNO3,0.1%~1.0% NaNO3 and 20%~30%PEG as chemical priming solution,The results showed that： the priming treatment of 500mg/L~2000mg/L GA3 significantly enhanced the germination of the Solanum Torvum seeds and the germination rate,the germination.energy and the germination index significantly increased with the increase of the concent ration of GA3,among which 1000mg/L～2000mg/L GA3 soaking 36h was the optimal treatment and the germination rate,the germination energy and the germination index were significantly increased by 27.39%~69.27%、195.33%~234.70%、1662.50%~1493.75% respectively,compared to the control.After treatment with 1000～2000mg/L GA3 soaking 36h,the Solanum Torvum seeds completed germination only requires 9 days,greatly shortened the germination time,the germination energy were significantly higher than those in control which completed germination needs 14 days.20% PEG has significantly promoting effect on the germination of Solanum Torvum seeds,but the germination effect significantly reduced by the increase of the concent of PEG,the germination rate,the germination index and the germination energy significantly decreased by 10.87%,19.06% and 57.25% treatmented with 40% PEG.The germination capacity of Solanum Torvum seeds promoted by 0.5%KNO3 priming solution treatments and the germination rate,the germination index and the germination energy significantly increased by 53.63%,77.56% and 185.71% respectively,compared to the control.The germination capacity of Solanum Torvum seeds inhibited by higher concentration of KNO3 priming solution treatments and significantly decreased with the increase of the concent ration of KNO3.NaNO3 priming solution treatments has no influenced on the germination rate,the germination index and the germination energy.
