Abstract:
Taking the tissue-cultured plantlets of Aronia melanocarpa as material，the effects of MS media concentrations，IBA concentrations，activated charcoal concentrations，rate of NO3-∶NH4+ on rooting of Aronia melanocarpa were studied，and growth media on root growth was acclimatized.The results showed that the best media for rooting of Aronia melanocarpa was 1/2MS+0.6 mg/L IBA+1.5 g/L activated charcoal+30 g/L sucrose+7 g/L agal.1/2MS was the suitable rooting medium with root length 3.2 cm.The hormone treatment of IBA 0.6 mg/L was better for growth with the root length 3.1 cm.When the rate of NO3-∶NH4+ was 3∶3，root amount was 4.3 with rooting rate 100.0%.The activated charcoal concentration of 1.5 g/L was significantly higher than other treatments，and the plant was healthy and strong，with unfolding leaves and much white and green fibrous root.The rate of humus∶sandy soil 1∶1 was the suitable medium for Aronia melanocarpa and the transplants had adapted to the regional climate of Yanji basically.
