Influences of Indole-3-Acetic Acid and Kinetin on Rooting and Indole Metabolism of Feijoa sellowiana1

Year: 1970

Type: article

Abstract: A series of 6 experiments was initiated October 9, 1964, to find root promoting or inhibiting factors in Feijoa sellowiana stem cuttings, to find a method of promoting rooting in difïicult-to-root plants, and to obtain information on indole metabolism in cuttings during the rooting process. The ability to root in response to IAA or kinetin varied greatly between clones. Both kinetin and IAA promoted rooting of one clone but had no effect on 2 others. Gas chromatographic analysis did not reveal any endogenous indole compounds in leafless stems. Indoles may have been present, but were masked by other compounds present in samples. IAA applied to cuttings was detected in samples taken immediately after treatment but not in samples taken 24 hr later. An unknown compound believed to be an inhibitor was found in both moderately easy and difficult-to-root clones but the content was 5 times higher in the latter. Effective levels of kinetin and IAA were found to be 0.10 and 70.00 mg/liter respectively when applied as an 8 hr basal soak.
