对3个籽瓜品种在8种恒温条件和6种变温条件下种子的发芽率进行了研究,发现籽瓜种子能够正常发芽的最低温度为15℃左右,最高温度为45℃左右,最适发芽温度为35℃。在变温处理中,影响籽瓜种子发芽的主要是平均温度的高低而非变温幅度的大小。籽瓜品种间在发芽温度上无明显差异。
The seed germination rate of three seed-melon cultivars under eight kinds of constant temperature conditions and six kinds of temperature-changing conditions was studied. The lowest germination rate of seeds was found to be about 15 ℃ and the maximum temperature was about 45 ℃. The optimum germination temperature was 35 ° C. In variable temperature treatment, the main impact of seed watermelon seeds germination is the average temperature rather than the size of the magnitude of temperature. There was no significant difference in seed germination temperature between seed and melon varieties.
