休眠对水稻种子的分析不利。为了评价破除IR64水稻种子休眠方法的有效性特进行本试验。现有的破除休眠的标准规程中没有一种方法是完全有效的!尤其是当休眠种子的百分数超过85％时。其中有一个标准规程,即浸种于lN的HNO_3中24小时,反而完全杀死了所有种子。最有效的破除IR64水稻休眠种子的方法是:先在50℃下预干燥5天;随后浸于自来水中24小时的两种方法相结合的处理。休眠对水稻种子的分析不利。为了评价破除IR64水稻种子休眠方法的有效性特进行本试验。现有的破除休眠的标准规程中没有一种方法是完全有效的!尤其是当休眠种子的百分数超过85％时。其中有一个标准规程,即浸种于lN的HNO_3中24小时,反而完全杀死了所有种子。最有效的破除IR64水稻休眠种子的方法是:先在50℃下预干燥5天;随后浸于自来水中24小时的两种方法相结合的处理。
Hibernation is not good for the analysis of rice seeds. This experiment was conducted to evaluate the effectiveness of breaking dormancy of rice seeds IR64. None of the existing standard procedures for breaking dormancy is completely efficient, especially when the percentage of dormant seeds exceeds 85%. There is a standard procedure, which is to soak in 1N HNO 3 for 24 hours, but completely kill all the seeds. The most effective way to break the dormant IR64 rice seeds is to pre-dry at 50 ° C for 5 days followed by a 24-hour immersion in tap water. Hibernation is not good for the analysis of rice seeds.
