Title StatementAsexual propagation on promising pili strains
General NoteCollege, Laguna: IPB, 1982. 69p. -(PCARR-IPB Proj. No. 824)
Summary, Etc.Four methods of asexual propagation were used to determine the response of promising pili trees. Other factors and conditions that influence the success of each method were also identified. Stem cutting did not show promise in rooting. However, ringing of shoots before planting of cuttings induced callus formation and initiated rooting. But this did not guarantee survival. Pili trees responded differently to marcotting. Only 48.08% responded favorably. Among female trees, rooting response was 53.49% while male trees had 22.22%. The use of IBA had also very little effect on the promotion of rooting. In marcots treated with 100 ppm NAA, leaf abscission was minimal within a week after treatment, while the control and those treated with 186.2 ppm NAA exhibited maximum defoliation three to four days after severance. Greater survival of newly severed marcots was obtained when placed under mist until they developed adequate roots and mature leaves. Twenty-five out of 30 marcots were successfully established by misting them. The percent success of cleft grafting ranged from 2.8 to 52.2%. The conditions required for a successful graft were discussed. Modified inarching (Thai method) gave 40-60% success in the dry season and 50-70% success in the wet season. C. luzonicum was also a useful rootstock in grafting pili. Budding success depended on the length of time the buds remained fresh and on the season of the year. In terms of number of sprouted buds, budwoods from young pili trees gave highest value than those from mature trees. In another trial, however scions from mature trees gave higher bud take than those from young trees
