植物组织培养,近二十年来有了飞跃的发展。果树这种多年生的高等植物,一般都用营养系繁殖,品种种质老化,病毒寄生蔓延,影响生长发育。茎、叶、根、花、果、种胚、胚乳、珠被细胞、胚囊细胞都可以在人工控制下进行营养系繁殖,无病毒的茎尖细胞培养,可以迅速培养无病毒苗,两个月一代进行工厂化育苗。茎尖培养在-196℃低温保存种质资源,上面滴几点油复盖,可以代替果树的种质资源圃的建立。近年 Plant tissue culture, the development of leap in the past two decades. Fruit tree perennial higher plants, are generally used to breed nutrition, germplasm species aging, parasitic spread of the virus, affecting growth and development. Stem, leaf, root, flower, fruit, embryo, endosperm, bead cells and embryo sac cells can all be nurtured under artificial control. The virus-free shoot tip cells can be rapidly cultured and virus- Month generation factory nursery. Stem tip culture at -196 ℃ low temperature preservation of germplasm resources, a few drops of oil above the cover, you can replace the establishment of fruit trees germplasm resources. in recent years
