Abstract:

In this article the method of pepper seed priming was optimized. Pepper seeds were used as material, oscillator was used as priming tool, chemical medicine and H2O were used to prime pepper seeds. Germination characters of primed pepper seeds were measured. The results showed that germination characters and resistance of the primed seeds had both been improved. The treatment (1) ‘1.8% KNO3+0.2% ZnSO4, 4 d’ was the optimal among all the treatments. The germination rate of the treatment (4) ‘10% PEG+1.8% KNO3+0.2% ZnSO4, 6 d’ declined obviously when primed three months later, although it was the best in half a month. In a word, the best priming method was ‘1.8% KNO3+0.2% ZnSO4, 4 d’.
