    PROMOTION OF ANNONA CHERIMOLA INVITRO SHOOT MORPHOGENESIS AS INFLUENCED BY ANTIOXIDANTS
    (1991) JORDAN, M; ITURRIAGA, L; ROVERARO, C; GOREUX, A
    Nodal sections, internodes, and zygotic embryos of Annona cherimola 'Concha Lisa' were cultivated in vitro in several phytohormone combinations to trigger morphogenesis. De novo multiple shoot formation was the most common response. Various antioxidant compounds, especially PVP, ascorbic acid, and glutathione enhanced this effect and reduced browning, while DIECA and aminooxyacetic acid were less effective in the concentrations tested. Citric acid and cysteine were not beneficial. Combinations of PVP with casein hydrolysate in presence of NAA 0.5 mg/l plus BA 2.0 mg/l were the best blends to promote shoot formation and yielded the highest number of shoots per explant.
