利用植物组织培养大量繁殖种苗,在兰花中的应用最早。种子繁殖时,从种子萌发到开花需要6～7年。如果从亲本植株获得相同的材料,进行分株等无性繁殖,就会缩短开花期。随着植物组织培养技术的开发,从茎尖取出到开花株只要4年左右时间,并且在短期内得到大量繁殖。下面介绍蕙兰组培培养大量繁殖的操作顺序。1、母株的选择选择花和叶片的形态、颜色、株形、生长发育状态良好的植株。
Plant tissue culture using a large number of breeding seedlings, the earliest application of orchids. Seed breeding, from the seed germination to flowering takes 6 to 7 years. If the same material is obtained from the parent plant, vegetative propagation such as ramets will shorten the flowering period. With the development of plant tissue culture technology, it takes only about 4 years to remove the flowering stem from the shoot tips and obtain large-scale propagation in a short period of time. The following describes Cymbidium cultivation of large numbers of breeding operation sequence. 1, the mother of the choice of flowers and leaves the choice of morphology, color, plant shape, good growth and development of plants.
