    EFFECTS OF NITROGENOUS BASES ON ROOT-FORMATION OF HYPOCOTYLS FROM PRUNUS-AVIUM L MERICIER AND BING GROWN-INVITRO
    (1982) JORDAN, M; ITURRIAGA, L; FEUCHT, W
    The rooting capacity of hypocotyl segments of sweet cherry cv. Mericier and Bing was investigated. NAA [naphthaleneacetic acid] (1 mg/l) and kinetin (0.1 mg/l) stimulated root induction (''Mericier'' 82.9%, ''Bing'' 44.4%). Without kinetin rooting was reduced to 37.1% in ''Mericier'' and to nil in ''Bing''. Purine and pyrimidine bases enhanced root formation. Cytosine proved optimal (''Mericier'' 80%, ''Bing'' 55.6%).

    INHIBITION OF ROOT-FORMATION IN PRUNUS-AVIUM HYPOCOTYLS BY CHLOROGENIC ACID INVITRO
    (1980) JORDAN, M; ITTURRIAGA, L; FEUCHT, W
    Etiolated hypocotyls of difficult to root P. avium were grown in vitro and were induced to form adventitious roots on a modified Murashige and Skoog medium. Naphthalene acetic acid at 1.0 mg/l together with furfurylaminopurine at 0.1 mg/l were most active (97.5%) in promoting roots. Chlorogenic acid supplied to the media at different concentrations reduced root formation and callus growth; the content of total phenolics was also reduced.
