PROPAGATION OF JABOTICABA (MYRCIARIA CAULIFLORA (MART.) BERG) BY TERMINAL LEAFY CUTTINGS
Trials were done to propagate jaboticaba by terminal leafy cuttings. These included determining: age of cutting; substrate (peat moss, sand or a mixture of both); time of year; rooting environment (misting vs hermetically sealed plastic chamber under 50% shade); and rooting stimulation (0, 1000, 3000 and 8000 ppm IBA and/or basal wounding). Around 60% of the cuttings under the hermetic plastic chamber rooted consistently from June to September. Rooting started after 4 – 5 months and 1 to 2 roots per cutting were obtained. The best cutting was a 10 cm terminal cut just below a node, left with the upper 3 – 4 pairs of leaves that had just matured, terminals with young leaves did not perform well. The best substrate was a 50 – 50% peat moss-sand mix. The best stimulus was wounding the bark with 4 longitudinal cuts made with a razor blade along the basal cm of the cutting plus 1000 ppm IBA, although wounding alone was almost as effective. Cutting at the middle of the internode was almost as good as below a node. Misting did not work well due to power failures and too cold water. Cuttings taken in October rooted poorly due to cold nights in December - January. From November to May the plants were very stressed by drought.
