Abstract

The objective of this research is to find out the early information of optimum light intensity and highest mycorrhizal colonization on natural Ramin seedling which it includes in semitolerant plant. The research was conducted in Ramin Natural Forest of Sungai Pelunjung Labai, Sanggau District, West Kalimantan for a year. The results of the research show that there are correlations between light intensity with mycorrhizal colonization. Ramin seedling which grown under the light intensity 3190 – 9500 lux have high mycorrhizal colonization and their growth better than the other treatment. Meanwhile Ramin seedling which grown in closed area or in open area with light intensity less than 1670 lux and more than 10840 lux respectively have lower mycorrhizal colonization and their growth was lower.Key words: Ramón seedling  (G. bancnus), Light intensity and Mycorrhizal Fungi

Abstract

The progeny trial of Shorea leprosula was established in Central Kalimantan under the IUPHHK-HA management of PT. Erna Djuliawati by planting 30 families to examine the genetic superiority of  trees as plywood raw material. The trial was laid-out using  8 blocks, 4 tree-plots and a spacing of 6 x 3 m. The aim of the study was to practice the plus trees selection in the progeny trial. The study was conducted using a survey method on phenotypically superior trees based on a diameter at breast height (dbh) baseline of ≥ 30 cm. The data collected and analyzed for the plus trees and comparison trees were total tree height (m), dbh (cm), and dbh increment (cm/yr). The results of the initial selection showed that 110 trees from 29 families were selected as candidate plus trees in the progeny trial. Futhermore, the honest significant difference test (BNJ) and scoring showed that there were 15 trees from 9 families that can be designated as plus trees.

Abstract

Agarwood is a type of semi-tolerant plant, so that for planting the seedlings should be grown under the shade. For planting in open land, it requires treatment in which one of them is using seedlings inoculated with arbuscular mycorrhizal fungi. The aim of the research is to obtain information on agarwood growth that has been inoculated with fungi mycorrhizal arbuscular when planted in the open land and ability to grow between agarwood seedlings inoculated mycorrhizal that was planted in the shade and in the open area. Split plot randomized block design was applied with treatments: the first plot consisting of plant had been inoculated with mycorrhizae and without mycorrhizal inoculation, and the sub plot was the types of shading that consists of open land, paranet 60 % intensity and natural vegetation. To reduce variabilty of site topographical differences were separated as bloks. Variables measured were: plant height (cm), stem diameter (mm), number of leaves, and survival percentage of plant. The results show that the height and diameter growth of seedlings innoculated with mycorrhizae were higher than non innoculated. The seedlings innoculated with mycorrhizal fungi were planted in the paranet shading grew better and significantly different compared to the vegetation shading. Seedlings innoculated mycorrhizal that were planted in open land grew better and significantly different compared to vegetation shading. This study results indicate that planting agarwood in the open land can be done using seedlings inoculated arbuscular mycorrhizal fungi. Key words: agarwood plant, arbuscular mycorrhizal fungi, shading and open land
