【摘要】 枣树愈伤组织培养所形成的不定芽（茎），在 Ｍ Ｓ（１／２ Ｎ Ｏ－３ ）附加生长素的培养基上分化出了不定根。在三种生长素的应用中， Ｉ Ｂ Ａ 效果最好，其次是 Ｉ Ａ Ａ， Ｎ Ａ Ａ 生根率低、且会脱分化形成大量愈伤组织。叶能促进不定根分化。光和细胞分裂素 Ｂ Ａ 则会抑制不定根分化，但在不定根产生后，光的抑制作用则被解除。更多还原

【Abstract】 On MS medium with 1/2 NO3 added with auxins jujube adventitious roots occurred in the adventitious buds developed from callus culture.Amongst the three auxins used, IBA proved to be the most effective in root inductin, while NAA showed the least efect and IAA effected in between.NAA also resulted in dedifferentiation and hence numerous new calluses formed. Leaves helped the adventitious roots to be formed whereas light and BA the auxetic inhibited their formation. However, the inhibiting effect of light no longer existed after the adventitious roots took their place.更多还原
