我们这个地方播种杂交稻威20母本,习惯于催芽播种,结果常因温湿掌握不好而发生“烧桶”或“烧包”问题,影响制种的计划面积.根据作者多年实践体验,杂交稻亲本之一的母本,可能由于先代受生长激素“920”的影响,种子内酶活性增加而较一般常规稻种代谢旺盛,只要外界温湿度条件比较适宜,不需采取什么增温措施,种胚就会很快萌动,破胸发芽。为了证实这一设想,作了催芽与
Our local sowing hybrid rice Viagra 20 female, accustomed to the germination sowing, the results often due to temperature and humidity control and the occurrence of “burning barrel” or “burning package” problem, affecting planted area .According to the author many years of practical experience, hybrid The female parent of one of the rice parents may be due to the influence of the growth hormone “920” in the first generation, and the enzyme activity in the seed is increased compared with that of the conventional rice varieties. As long as the external temperature and humidity conditions are relatively suitable, no warming measure needs to be taken, Embryo will soon germinate, broken chest sprouting. In order to confirm this idea, made a promotion and
