Hormonal and nutritional factors affecting shoot growth of papaya in vitro



Hormonal and nutritional factors affecting shoot growth of papaya in vitro



Kagawa Daigaku Nogakubu Gakujutsu Hokoku 49(2): 165-170



Effects of hormonal and nutritional factors influencing shoot growth of papaya (Carica papaya L. ) in vitro were studied. BA at 1muM markedly increased bud number, while 2 iP and Kinetin at 1muM enhanced shoot elongation. Although CPPU also stimulated bud proliferation, it caused the reduction in size and discoloration of leaves. Addition of NAA to the medium containing BA or 2iP promoted neither multiplication nor elongation. At higher concentration, NAA rather reduced the both. Either multiplication or elongation of shoot occurred most actively on the medium containing macro components at full strength within the range from 1/4 to 4 MS.
