摘要: The regeneration of adventitious shoots on leaf segments taken from in vitro the apple rootstock 'Jork 9' was examined. Among macroelements and organics tested (MS, LS or N?), MS most effective. best combination naphthaleneacetic acid (NAA) benzyladenine (BA) 2.7 pM 17.8 pM, respectively, resulting 70% expiants with shoots. 0.1 thidiazuron (TDZ) also resulted a high percentage but almost all were hyperhydric. Only adaxial surface contact medium showed regeneration. Basal within had higher than distal expiants. Cell divisions, localized near vascular bundles, observed after three days culture. first vegetative buds regenerated directly tissue, whereas that appeared later callus.
