Abstract:

In the production, we know that the germination rate of gourd seeds was low, the requirements of seeds was large and the budding time was different, so it was very difficult to determine the grafting time for watermelon. In order to solve these problems, we thought up two new methods to improve the indicators of gourd seeds, one of them was alternating wet seed, the other was NaCl treatments. In our research, we studied the effects of the two methods on germination rate, germination index, vigor index and radical length of the gourd seeds. The result showed that wet and dry alternately soaking method can significantly improve germination index and vigor index of the gourd seeds, and the germination time significantly shortened. Soaking the gourd in which the optimum time of 8 hours, then the seed of the indicators was better than other treatments. Different concentrations of NaCl treatment on gourd seeds showed that the optimal NaCl concentration was about 10 mmol/L, then gourd seed germination trend, germination rate and vigor index were relatively high.
