以巴戟天幼嫩种子中的胚为外植体进行组织培养诱导出愈伤组织,继而诱导分化出芽,长成小苗。将小苗转入生根培养基中,从茎基部诱导出不定根,再生植株。对离体苗的不定根发育进行结构观察,发现巴戟天组培苗的不定根是由形成层细胞先分裂分化形成根原基后发育而成的。
Using the embryos in the young seedlings of Morinda officinalis as explants, the callus was induced and then the buds were induced to differentiate and grew into young shoots. The shoots were transferred to rooting medium to induce adventitious roots and regenerated plants from the base of the stems. Morphological observation on adventitious root development of in vitro seedlings showed that Adventitialis of Morinda officinalis plantlets developed after the first division of the cambial cells to form the root primordium.
