Abstract

This study was conducted to evaluate plant growth of Intsia bijuga at 5 years old in Sobang, Banten for supplying good genetic material in the future. Establishment of the trial was conducted in 2007 using Randomized Complete Block Design (RCBD) that consisted of 6 blocks, 100 families nested in 10 provenances, 4 treeplot for each family with a spacing of 4 x4 m. Measurements were taken periodically every year on the survival percentage, total height and stem diameter at the breast height or dbh. At the age of 5 years showed that the significant differences among provenance in survival percentage that ranged from 41.61 to 65.11 %,  average of plant height were 1.04 to 2.82 m and dbh 1.24 to 1.59 cm. The growth variation families also showed significant differences in height and diameter. The survival rate ranged from 12.5-91.67 %, average plant height were 0.52-2.55 m and dbh 0.90-2.44 cm. Individual tree heritability estimate for height was height (0.344) while that of diameter was moderate (0.259). Family heritabilities for height and diameter was considered moderate, namely 0.573 and 0.491 respectively. Genetic correlation between height and diameter growth was positive and high (0.834).

Abstract

The purpose of the study is to know the plant growth merbau by vegetative propagation of shoot cutting from 12 populations at dry areas of Gunung Kidul Yogyakarta. Twelve of these populations originated from Carita Banten, West Java, Mandopi Papua, Minamin East Halmahera Maluku, Nabire Papua, Nusajaya Halmahera Maluku, Oransbari Papua, Pacific land race Darmaga Bogor West Java, Twanwawi Papua, Waigo Papua, Wasior Papua, Seram Maluku. The design of RCBD with 12 populations consisted of totally 120 mother trees, 5 blocks, 3 treeplot, 6m x 2m trunk. The caracter traits measured were plant height, diameter of plant and survival rate at 2,5 years old. The result of varian analisis showed there are significant differences among populations that are tested on height, diameter and survival rate. From the result of research that the Pacific land race Darmaga Bogor West Java is the best growth on height 81,4cm and diameter 8,9mm. The highest of survival rate is from Oransbari Papua 82,72%. Average plant height growth Merbau at the site of the study is 61,3cm, the mean diameter 7,8mm and survival rate 63,55%.
