香蕉组培中矮化变异从生根培养后就呈现假茎较矮粗、叶柄和叶片较短阔的性状，植株对ＧＡ３的增高反应与正常株相似，其染色体数多于正常数目的细胞明显增多。嵌纹叶变异在假植后才逐渐显症，显症迟早与品种、生长条件等有关，其染色体数少于正常数目的细胞数尤其是二倍体细胞明显增多。这两种变异均可通过吸芽和组培繁殖遗传
The dwarf variation in banana tissue culture showed pseudotyped stems shorter and thicker than those of the normal plants after rooting. The plant growth response to GA3 was similar to that of the normal plants, and the number of chromosomes in banana tissue culture increased more than the normal number . Embryo leaf variation in the fossa after planting gradually obvious disease, prompting sooner or later with the variety, growth conditions and other related, the number of chromosomes less than the normal number of cells, especially diploid cells increased significantly. Both variants can be inherited by bud and tissue culture
