Eugenia (Eugenia myrtofolia L.) is one of the most demanded ornamental plant in landscaping industry but the availability of planting material of this plant is limited due to its difficulty in propagating by stem cutting. Thus, this study was conducted to: (1) determine the influence of bottom heat on the regeneration of Eugenia stem cuttings; (2) determine the influence of type of cutting on the regeneration of Eugenia stem cuttings; and (3) evaluate the interaction effect of the type of cutting and bottom heat application on the regeneration of Eugenia stem cuttings. This was conducted at NwSSU of San Jorge Campus, San Jorge, Samar. The experiment was laid-out in 2 x 3 factorial in split-plot arranged in RCBD with three replications. The rootin g medium temperature manipulation (B1- with bottom heat and B2- without bottom heat) was assigned in the Main-plot while the of cuttings (T1-with no axillary shoot, T2- with single axillary shoot, and T3-with two axillary shoot) in the sub-plot. Regardless of the type of cuttings, bottom heat application did not significantly influenced all cutting regeneration parameters evaluated but significantly affected some horticultural characteristics of the successfully regenerated cutting 30 days after potting. Application of bottom heat significantly promoted shoot production both in terms of number of shoot and size of leaves of successfully regenerated cuttings. The type of cutting significantly affected the percent leaf retention and rooting. Cuttings without axillary shoot
retained more leaves and gave higher roofing percentage than cuttings with 2 shoots. Successfully regenerated cuttings with 1 and 2 axillary shoots retained had bigger leaves 30 days after potting than cuttings without axillary shoot. There was no significant interaction effect of rooting medium temperature manipulation and type of cuttings on the regeneration of Eugenia stem cuttings and the performance of regenerated cuttings after potting.
