近年来农业生产上,特别是在杂交水稻的生产上,赤霉素的应用已成为增产的重要和必要措施。但自六十年代以来,国内赤霉素(Gibberellins,GAs)生产的菌种(GibberelIa fujikuroi)在产量上一直处于较低的水平,高产菌株的筛选育一种直无重大突破,因此培育筛选高产的赤霉菌株,已是生产上需要迫切解决的问题。过去在菌种产量上未有突破的原因,一方面可能是该菌种的育种难度大、而创造和积累有利变异的手段较落后;另一方面筛选方法极
In recent years, agricultural production, especially in the production of hybrid rice, gibberellin application has become an important and necessary measures to increase production. However, Gibberella fujikuroi, a strain of domestic Gibberellins (GAs), has been at a relatively low level of production since the 1960s. There is no major breakthrough in selection and screening of high-yielding strains, so breeding high-yield screening Gibberella strain, is the production needs urgent solution to the problem. In the past, there was no breakthrough in the production of bacteria. On the one hand, this strain may be difficult to breed, and laggard means of creating and accumulating favorable variations. On the other hand,
