油菜如果能够通过无性繁殖顺利生根并开花结实,这不仅可加速良种繁殖,而且对改进育种和栽培研究工作,也具有一定的意义。因此,近两年我们对油菜无性繁殖的可能性进行了探索:选用甘兰型中熟良种“西南302”,在不同生长时期,对不同部位的茎段以及不同部位的叶片进行扦插土培或水培,观察它的发根生长情况。现将初步结果简述如下: 1、苗期茎段扦插:
If rape successfully rooted and flowered through asexual reproduction, this not only accelerated the breeding of elite seeds, but also had some significance for the improvement of breeding and cultivation research. Therefore, in the recent two years, we explored the possibility of asexual reproduction of rapeseed. By selecting “Southwest 302”, a moderately-matured cultivar of “kulan” type, in different growth stages, the stem segments of different parts and the leaves of different parts were cuttage and soil- Hydroponics, observe the growth of its hair roots. The preliminary results are summarized as follows: 1, seedling stem cutting:
