| Popis: | Eugenia (Eugeniamyrtofolia L.) is one of the most demanded ornamental plant in landscapingindustry but the availability of planting material of this plant is limited dueto its difficulty in propagating by stem cutting. Thus, this study wasconducted to: (1) determine the influence of bottom heat on the regeneration ofEugenia stem cuttings; (2) determine the influence of type of cutting on theregeneration of Eugenia stem cuttings; and (3) evaluate the interaction effectof the type of cutting and bottom heat application on the regeneration ofEugenia stem cuttings. This was conducted at NwSSU of San Jorge Campus, SanJorge, Samar. The experiment was laid-out in 2 x 3 factorial in split-plotarranged in RCBD with three replications. The rooting medium temperaturemanipulation (B1- with bottom heat and B2- without bottom heat) was assigned inthe Main-plot while type of cuttings (T1-with no axillary shoot, T2- withsingle 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 cuttingregeneration parameters evaluated but significantly affected some horticultural characteristics of thesuccessfully regenerated cutting 30 days after potting. Application of bottomheat significantly promoted shoot production both in terms of number of shootand size of leaves of successfully regenerated cuttings. The type of cuttingsignificantly affected the percent leaf retention and rooting. Cuttings withoutaxillary shoot retained more leaves and gave higher rooting percentage thancuttings with 2 axillary shoots. Successfully regenerated cuttings with 1 and 2axillary shoots retained had bigger leaves 30 days after potting than cuttingswithout axillary shoot. There was no significant interaction effect of rootingmedium temperature manipulation and type of cuttings on the regeneration ofEugenia stem cuttings and the performance of regenerated cuttings after potting |
