５个陆地棉品种组织培养结果表明，品种间出愈难易程度差异很大。出愈率高未必胚性愈伤组织发生率就高。只有灰白、半透明和褐色愈伤组织才能发生胚性愈伤组织。ＫＴ和２．４Ｄ配合使用能提高胚性愈伤组织发生率；ＩＡＡ和ＫＴ配合使用有利于胚状体的萌发和植株再生
Tissue culture results of five cultivars of G. hirsutum showed that there were great differences in the ease of emergence and development of the cultivars. The higher the rate of embryogenic callus may not be high incidence. Embryogenic callus occurs only in gray, translucent and brown callus. KT and 2.4 D with the use of embryogenic callus can improve the incidence of; IAA and KT with the help of embryoid body germination and plant regeneration
