Vegetative propagation of Acacia mangium Willd. and Casuarina cunninghamiana Miq. by cuttings

Two separate studies on vegetative propagation by means of cuttings were undertaken at the shedhouse of the central nursery of Bukidnon Forests, Inc. in Barangay [village] Kalasungay, Malaybalay, Bukidnon [Philippines] to determine the rootability of Acacia mangium Willd. and Casuarina cunninghamiana Miq. in various levels of hormone concentrations using several type of rooting media. The rooting experiment of A. mangium was done under mist in ordinary open shedhouse conditions while the rooting experiment of C. cunninghamiana by means of spring used cellophane-covered basins with growing media under intermittent misting. A. mangium cuttings showed 46.67 percent rooting success while C. cunninghamiana cuttings produced 47.78 percent. There were no significant effects on the type of growing medium, type of cuttings and levels of concentration of IBA on the average number and length of microroots produced by A. mangium. The study revealed that BFI potting medium and coconut coir dust were both satisfactory growing medium for A.mangium. The type of cuttings based on the position on the shoot did not also show significant difference. The levels of IBA concentration nonetheless showed any significant variations. Percentagewise, the study however revealed that basal part of A. mangium cuttings, soaked in 200 ppm IBA and grown in BFI potting medium showed better rooting performance. In the case of C. cunninghamiana cuttings, the study showed that it could successfully root in cellophane-covered rooting condition under mist than in ordinary open shedhouse condition. There was significant effects of growing media and growth hormone on the number of macroroot produced but no significant effects were detected for shoot growth and volume of roots of C. cunninghamiana as well as on the interaction effects. The study revealed that C. cunninghamiana springs rooted when treated with 300 ppm and grown in either sand or coconut coir dust with perlite in cellophane-covered basin under intermittent misting
