[Objective] To establish in vitro culture system of kiwifruit endosperm. [Method]After disinfection of the seeds of kiwifruit,the endosperm was used as explant to inoculate on 1/2 MS medium containing different combinations of NAA and 6-BA. We investigated the effects of different 6-BA and NAA combinations on the organogenesis of kiwifruit endosperm callus tissue. [Result]6-BA preferably promote organogenesis of endosperm callus. The maximum induction frequency of the adventitious buds was observed in the c...
