ABSTRACT
DE GRANO, MA. VICTORIA P., Don Severino Agricul-tural College, Indang, Cavite, 1990. "Respoase of Black-pepper Cuttings to Different Levels of Alpha Naphthalene Acetic Acid (ANAA) and Rooting Media", Mr. Celso S. Crucido, Adviser.
The study was conducted from October 7, 1989 to January 7, 1990 at the Plantation Nursery, Don Severino Agricultural college, Indang, Cavite. The objectives were to determine the optimum level of ANAA that will induce rapid rooting response in blackpepper stem cut-tings and to identify the best rooting medium in propa-gating blackpepper stem cuttings. Three-node cuttings were used in this study. These were dipped for 12 hours at different concentration of Alpha Naphthalene Acetic Acid (ANAA), i.e., 100, 150, and 200 ppm. Some cuttings were not treated to serve as control. The cuttings were planted at the different soil media immediately after removing them from the solution. The different soil media used were combination of compost coir dust, and garden soil (S1), combination of compost, coffee hull, and garden soil (S2), combination of compost, rice hull, and garden soil (S3), and combination of com-post, sawdust, and garden soil (S4). Results of the study showed that untreated cut-tings grown in combination of compost, sawdust and garden soil had the least rinuili;3.r of roots and shortest IPTIO-11 of roots at 60 days and 90 days after planting. Application of ANAA regardless of the soil media used increased the percentage of rooting as well 13,3 the number and length of roots formed. Those treated with 200 ppm of ANAA and planted in combination with compost„ rice hull, garden soil (S) obtained the highest number and length of roots as well as the longest shoot 90 days after planting. This proved that 200 ppm of ANAA and combination of compost, rice hull and garden soil (SO favorably increased all the parameters observed in the study.Cavite.
