根据中华人民共和国国家标准农作物种子检验规程(GB3543—83),水稻种子发芽试验温度为30℃恒温或20～30℃变温,并于发芽前进行预备处理,即于30℃水中浸泡24小时。在实际工作中,按此技术规程对杂交稻父本明恢63(或酶选明恢63)进行发芽试验得到的结果与实际常常不相符,有明显偏低的现象;即使在春季播种前进行室内发芽试验仍有偏低现象,在秋季收购时很难把握发芽率从而直接影响
According to the People’s Republic of China National Standard for Crop Seeds Inspection (GB3543-83), the germination test of rice seeds is carried out at a temperature of 30 ° C or at a temperature of 20-30 ° C, and pre-germinated for treatment, ie soaking in water at 30 ° C for 24 hours. In practice, according to this technical regulation, the result of germination test of hybrid rice parent Minghui 63 (or enzyme Minghui-63) often does not accord with the actual results, which is obviously low; even before spring planting, Indoor germination test is still low, the acquisition in the autumn is difficult to grasp the germination rate and thus a direct impact
