Abstract

Abstract The study aims to know the effect of the timing of Paclobutrazol and complementary liquid fertilizer on the growth and yield of potato plains of medium and knowing the interaction between the timing of Paclobutrazol and other types of PPC. This research was conducted in October 2013 to January 2015 This study used factorial experiment with a randomized block design (RBD) consisting of: 6 combined treatment with 3 replications. Factor A: time paclobutrazol application on the age of the plant, namely A1 and A2 on the 30-day plant age 45 days. Whereas factor B: complementary liquid fertilizer consisting of B1: kristalon, B2: plant catalyst, B3: Gandasil D. Variables measured were plant height, amount of shoots, number of leaves, plant production and production samples perbedengan results showed that the results of research on Applications paclobutrazol significant effect on plant height, number of leaves, plant production and production samples of potatoes per plot and the number of shoots not significant. Interaction between the time of application of paclobutrazol and complementary liquid fertilizer does not give real influence. Keywords: organic C, Phosphorus, Potassium, Nitrogen, pH

Abstract

ABSTRACT Runtunuwu, S.D. and E.F. Lengkong. 2005. Identification of Isozyme Markers (PER-7, PER-8, and RAPD OBI7375) of Dwarf Salak Coconut (GSK) and its Tall Hibrids. Eugenia 11 (1): 8-17. The objective of this research was to identify PER-7 and PER-8 isozymes, and OB17 375 RAPD as molecular markers for resistance to NF Phytophthora disease in Genjah Salak (GSK) dwarf coconut and its several hybrids with Tall coconut at The Research Institute for Coconut and Palmae (RICP) Manado. Coconut resistance to NF Phytophthora disease was determined based on disease lesion size of inoculated coconut fruits at 7 days after inoculation. PER-7 and PER-8 isozymes marker were identified using horizontal starch gel electrophoresis, and OB17375 RAPD marker was identified based on polymerase chain reaction (PCR) using kit B number 17 primer (Operon Technologies, California). PER-7 isozyme marker could be used to select GSK x DTA (Dalam Tenga) and GSK x RLT (Rennell Tall) hybrid coconuts that resistant to NF Phytophthora disease. PER-7 isozyme without OB17375 markers (PER-7/-) could be used to select resistant GSK x WAT (West African Tall) hybrid coconut to the disease. Keywords: Isozymes, RAPD, Molecular marker, Phytophthora disease, coconut
