Abstract:
Terminal leafy cuttings of lucuma (Lucuma obovata H.B.K.) were taken in december from growing shoots, desinfected, treated with naphtalene acetic acid (NAA) at 0, 2 000, 4 000 and 8 000 ppm and planted under mist or sealed chambers consisting of wood trays covered with polyethylene film 1.5/1000" thick.
In both cases 50% shade was used and the rooting medium consisted of 1/3 sand, peat moss and 'Styrofoam' shavings, desinfected with methyl bromide.
The best results were obtained with 4 000 ppm NAA either under mist or sealed chamber with 78 and 80% rooting respectively for one ecotype and 69% for a second that was under mist only.
Rooting started after 50 days.
Sealed chambers, that gave the best results, would be preferred because of their simplicity in building and maintaining a proper environment, especially in rural areas.
