摘要
在iuphhong - ha管理的PT. Erna Djuliawati下，在加里曼丹中部建立了麻风树后代试验，通过种植30个家庭来检验树木作为胶合板原料的遗传优势。试验使用8个街区，4个树木地块，间距为6 x 3 m。本研究的目的是在子代试验中实践正树选择。本研究采用基于≥30 cm胸径基线的表型优势树种调查方法进行。正树和比较树的数据分别为总树高(m)、胸径(cm)和胸径增量(cm/yr)。初步选择结果表明，在后代试验中，从29个家系中选出110棵树作为候选加树。另外，经诚实显著差异检验(BNJ)和评分显示，9个科中有15棵树可以被指定为正树
SELEKSI POHON PLUS PADA UJI KETURUNAN Shorea leprosulaDI KALIMANTAN TENGAH
he 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 asplywood 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
