Rooting of jatropha curcas leaf-bud cuttings as affected by different IBA concentrations /
Jatropha curcas is a plant with great potential which can greatly contribute to biofue1 alternative as it can grow in a heat stress condition. It can be propagated by seeds and cuttings. Stem cuttings are usually chosen for a more unifonn growth and shorter time for growth. However, the number of cu...

| 520 | |a Jatropha curcas is a plant with great potential which can greatly contribute to biofue1 alternative as it can grow in a heat stress condition. It can be propagated by seeds and cuttings. Stem cuttings are usually chosen for a more unifonn growth and shorter time for growth. However, the number of cuttings produced are limited. Since, a lot of leaf-buds are available on the matured trees, mass production of planting materials can be produced from the leaf-bud cuttings if adventitious root can be induced at its base. Rooting can be induced using plant growth regulators such as exogenous auxin. Treating the leaf-bud cuttings with rnA (indole-3butyric acid), a type of auxin is belief to induce and improve its rooting ability. The best rnA concentration for optimized rooting of J curcas was investigated. Leaf-bud cuttings with two leaves and a bud of J curcas was treated with 0.1 % Benomyl solution before they were dip in different rnA concentrations (0, 1.0,2.5, 5.0, 7.5, 10.0 mglL). Later, they were transferred into pots containing perlite and watered once every two days. The experiment was conducted using RCBD design. The growth of the plants was monitored for six weeks before the percentage of leaf-bud cutting inducing root was recorded. Leaf-bud cuttings ofJ curcas that had been treated with 7.5 mg/L rnA concentration showed the best rooting perfonnance with highest percentage of leaf-bud cutting inducing root (70%), highest mean value for length of root (2.87 em) and number of leaf produced (2.30). there was also no callus fonnation recorded for the same treatment. However, all leaf-bud cuttings started to decay and died six weeks after planting. | ||
