Abstract

Mindi (Melia azedarach Linn., family Meliaceae) is a multipurpose forest tree species such as for furniture, vinier and plywood, otherwise the leaves for pesticide and medicine material. Mindi mostly cultivated in a community forest, especially in West Java. This study was aimed to assess the growth performance and genetic parameter of the progeny test of mindi at Parungpanjang Forest Research Station, Bogor, West Java. The progeny test was established by using a randomized complete block design, consisting of 6 blocks and 73 families and each family consisting of 4 trees row-plot. The survival at 7 years old was 57.48%, height was 7.15 m and diameter is 8.59 cm, in average. The height and diameter growths among families showed a significantly different. The best family growth in height and diameter were Sumedang-31 and Bogor-18 families, respectively.The individual and family heritabilities for both stem diameter and  tree heght characters were stil relatively low, with the higher family heritability value than individual heritability.  The genetic correlation between total height and stem diameter of 0.57 indicates a strong correlation between the traits.

Abstract

Trema orientalis L. is a potential species to be developed as a biomass-based renewable energy source. The use of quality seedling that can be done through vegetative techniques is one of the issues that determine the success of plantation development. The purpose of this research is to get the best cutting material and an optimal growth regulator for multiplication of shoot cuttings. The shoot cuttings were obtained from 12-month-old seedlings. The design used was a complete randomized design (CRD) factorial pattern with two factors, namely cuttings positions (shoot, middle and bottom parts) and concentration of naphthalene acetic acid (NAA) growth regulator of 0, 50, 100, 150, 200, 250, and 300 ppm. The result showed that T. Orientalis propagation can be carried out well by using seedling shoot section soaked in NAA 300 ppm for 10 minutes. The treatment was able to have the percentage of rooting cutting of 71.67percent, number of roots of 6 pieces, root dry weight of 0.088 g, and shoot dry weight of 0.148 g.
