葡萄品种繁多,基因型高度杂合,育种周期长,在有性或无性繁殖的过程中易造成基因型分离,降低品种价值.而通过顶芽、腋芽增殖的途径实现葡萄离体快速繁殖,简便易行,受基因型影响小,遗传性稳定,苗发育正常健壮容易移栽.我们在不断试验的基础上,实现了每月2.5～4.6的增殖倍数,短期内可生产大量优质组培全株苗,这将为缓解苗木紧缺,发挥良种栽培的增益效果,起到促
Grape varieties, genotypes are highly heterozygous, breeding cycle is long, easy to genotype separation and reduce variety value in the process of sexual or asexual reproduction.But through the way of terminal bud and axillary bud multiplication, Easy to be affected by the genotype of small, hereditary stability, seedlings grow normally healthy and easy to transplanting. We continue to test based on the achievement of a monthly multiplication of 2.5 to 4.6 times in the short term can produce a large number of high quality tissue culture whole plant Miao, which will alleviate the shortage of seedlings, play good breeding effect, played a catalytic role
