Abstract
Eugenia (Eugenia myrtofolia L.) is one of the most popular ornamental plant used in landscaping industry but success of rooting of this plant is very low due to its difficulty in propagating by stem cutting. Hence, this study aimed to: (1) determine the influence of different levels of Naphthalene Acetic Acid (NAA) on the regeneration of Eugenia stem cuttings; (2) determine the influence of bottom heat application on the regeneration of Eugenia stem cuttings; and (3) evaluate the interaction effect of bottom heat treatment and the different levels of concentration of Naphthalene Acetic Acid (NAA) 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 5 split-plot arranged in RCBD with three replications. The Main-plot was rooting medium temperature manipulation (B1- bottom heat and B2- without bottom heat) and the levels of NAA (T1- o ppm, T2- 500 ppm, T3- 1000 ppm, T4- 1500 ppm, T5- 2,000 ppm, and T6- 2,400 ppm) was the sub-plot. Application of bottom heat in the rooting medium significantly increased percent rooting and number of primary roots. It also increased length of shoots and number and width of leaves regenerated Eugenia stem cuttings 30 days after potting. Moreover, regardless of bottom heat treatment, application of Naphthalene Acetic Acid significantly enhanced leaf retention; increased rooting percentage; number, diameter and length of roots; fresh and dry weight of roots; and roots starch and sugar contents. It also significantly improved the length and number of axillary shoots and number, length and width of leaves of the regenerated cuttings 30 days after potting. NAA concentration of 2,000 ppm was the optimum concentration for successful regeneration of Eugenia stem cuttings. There was no significant interaction effects between bottom heat and Naphthalene Acetic Acid application on the regeneration of Eugenia stem cuttings and the horticultural characteristics of the regenerated cuttings after potting.
