| 摘 要： | 磁场对解除籼稻种子的休眠作用,因品种而异.根据磁场处理后种子发芽率的变化,可将籼稻品种(品系)分为正反应、负反应、迟钝三种类型.正反应品种的种子一般在接受0.2—0.6T磁场处理后,发芽势和发芽率提高;负反应品种的种子用0.1—1.0T磁场处理后,发芽势和发芽率降低;迟钝品种则无显著变化。

| Abstract: | Seed germination is greatly inhibited by dormancy in indica rice for some varieties. In order to enhance germination, magnetic field was used to treat ripe seeds shortly after harvest for dif- ferent varieties of indica rice. According to the reaction to the magnetic field, the varieties could be divided into three groups: A. Varieties with a positive reaction, germination power and germinaton rate were significantly higher than the contrast. The effective dose was about 0.2-0.6T. B. Varieties with a negative reaction, germination power and germination rate were notably lowered. The effective dose was about 0.1-1.0T. C. Varieties with dull reaction, no sig- niflcant difference was found in germination rate after treatment. |
