Abstract

An open-pollinated progeny test of Araucaria cunninghamii was established in Bodowoso, East Java.The seeds were collected from 28 parent trees in 3 provenances in papua. The progeny test was arranged according to randomized Complete Block Design consisting of 28 families, 8 replications, 4 lines tree plot and spacing at 4 m x 3 m. At five years of age differences between provenances or families within provenance was significant for height, diameter and stem straightness. Heritability estimates for height, diameter and stem straightness were all moderate: (h2f – 0.44, h2i =0.11) for  height, h2f – 0,36 h2i =0.12) for straightness). The genetic corrwelations between traits were strong and positive: 0.62 for height and diameter, 0.73 for diameter and straightness (rg=0.73) and height and straightness. The genetic gains from family selection with  selection intensity of 70 % for height, diameter and stem straightness were 7.8 %, 2.5 %, and 9.7 % respectively, While those from individual selection with selection intensity of 10 % for height, diameter and stem straightness were 10.7 %, 4.6 % and 15.3 % respectively.

Abstract

The objective of the study was to increase the growth of 5 provenances albizia (Paraserianthes falcataria L. Nielsen) in the nursery. The experimental design was Split Plot Design, with 5 provenances of albizia as main plot and 3 treatment (wood vinegar application, mychorrizae application and control) as sub plot. Each sub plot consited of 45 seeds as sample,. Growth parameter observed was delta height: that is different beetween measurement at the early application (3 weeks age of seedling ) and at the last measurement (10 weeks age of seedling). The data obtained then analyzed by using analysis of variance of continued with Duncan test. The result showed that mychorrizae and wood vinegar application have significant effect on the growth of albazia seedling. The best performance was shown at wood vinegar application (height average 75,48 cm and height delta 66,62 cm), mychorrizae application (height average 66,44 cm and height delta 59,22 cm) and control (height average 58, 92 cm and height delta 52, 48 cm) respectively. Provenance differences were also significant. The best performance  were shown at provenance of Candiroto, Kediri, Ciamis, Wamena dan Subang. Height delta each provenance after 7 weeks application were 67,65 cm, 62,93 cm, 60,15 cm 53,37 cm dan 53,11 cm; while the total height at the 10 weeks age of seedling were 74,44 cm, 69,33 cm, 69,14 cm, 61,02 cm dan 60,80 cm respectively.

Abstract

Screening primer is an effective method to develop microsatellite markers from related taxa. Aim of this study was to develop microsatellite markers of four Shorea producing tengkawang oil, i.e. Shorea gysbertiana, Shorea macrophylla, Shorea pinanga and Shorea stenoptera by screening microsatellite primers of Shorea curtisii. Leaf samples of the four Shorea were collected from nursery at Center for Forest Biotechnology and Tree Improvement Research in Yogyakarta. Four microsatellite primers of S. curtisii i.e. Shc-1, Shc-2, Shc-7 and Shc-9 had been used to screen. Results showed that numerous alleles were shared among the Shorea. The expected heterozygosity (HE) for locus Shc-1 ranged between 0.594 and 0.722; locus Shc-2 ranged between 0.219 and 0.611; locus Shc-7 ranged between 0.594 and 0.778; and locus Shc-9 ranged between 0.594 and 0.844. Coefficient of inbreeding (FIS) value was low and it was insignificant deviated from Hardy-Weinberg Equilibrium (HWE) at  almost all loci except Shc-1 of S.  pinanga. A dendrogram showed two clusters; S. gysbertsiana and S. macrophylla represented in one cluster, while S. pinanga and S. stenoptera represented in another cluster. Therefore the developed microsatellite markers are possible to be applied for studying population genetics and mating system of these species.

Abstract

Bakau (Rhizopora apiculata(, one of the species of mangrove, is well known for having true recalcitrat seeds, since they tend to have very short-life cycle. Hence they cannot be stored a long time. Developing improved methods for retarding seedling growth of tropical mangrove is necessary to successfully control growth rates during long-term storage. The aim of the research is to identify the influence of growth inhibitors used were paclobutrazol (250 ppm), NaCl (0,5 %) and aquadest (as a control). The condition for the storage consists of heavy (650 lux), moderate (8935 lux) and light (17593 lux) shadings. The media used including the mixture of sand. A completely randomized design was arranged in a factorial experiment. The results showed that the use of paclobutrazol (250 ppm) was very effective to suppress the growth height of the seedlings. The storage condition of light shading with the intensity of the  day-light and the highest temperatur (L.I= ±17593 lux, T= ±350C) could reduced the speed of seedling growth during storage for 6 months supported by the use of sand as media. Such conditions gave a seedling survival of 98,33%

Abstract

The research aimed to assess genetic variations, estimated heritability and genetic gain in resin yield of P. merkusii. The study was conducted on a half-sib progeny test of 4-year-old P. merkusii resin yield plantation at compartment 37C RPH Lumbir BPKH Samudra KPH Banyumas Barat, using incompletely-block-row-column design by sub-line system (sub-line SSO Jember 1, SSO Sumedang 1, Sulawesi 1, Sulawesi 2 and Jatim 2). Variables measured were average of resin yield from two drillings on the right and left trunk using 10 mm drill bit at 50 cm height from the ground. Genetic variation for resin yield between family was significant different except for sub-line SSO Jember 1. Estimated component variances of family for the sub-line SSO Sumedang 1, Sulawesi 1, Sulawesi 2 dan Jatim 2 were 8.92%; 9.87%; 7.53% and 6.74%, respectively. Individual heritability values were 0.39; 0.42; 0.36; 0.29 and family heritability were 0.59; 0.49; 0.50; 0.48 respectively for the sub-line SSO Sumedang 1, Sulawesi 1, Sulawesi 2 and Jatim 2. Expected genetic gains in resin yield were 14.5%, 10.5% and 6.6% using intensity of selection of 10%, 25% and 50%, respectively. Sub-line Sulawesi 1 had the highest estimated genetic gain and sub-line Jatim 2 was the lowest

Abstract

The study was conducted to investigate the existence of  family × site  interactions observed in  second generation  open-pollinated progeny test  of  Acacia mangium in two locations: Lipatkain, Riau (Sumatra) and  Kenangan, East Kalimantan.  The progeny tests were  established   using  51-55 families  originated  from Oriomo River Papua New Guinea  provenance. There were 31common families tested at the both sites. Growth on both sites was significantly different between families. The average  height  and diameter was 15,9 m and  13,3 cm  respectively at  Kenangan, and  17,0 m and  16,6 cm  respectively at  Lipatkain. Family × site interactions  were  highly significant for height and diameter. The ratio of variance component of interaction to the family variance component (s2fl / s2f ) for  diameter (1,6) and height (1,2) were largerr than  Shelbourne’s  critical value (0,5),    indicating the low   genotypic stability at family level for the both traits  where the  diameter was  more sensitive than height to changing  site conditions. Genetic correlations between the same trait at different sites were low:  0.45 for height  and 0.38 for diameter. The greatest genetic gain and relative efficiency of family selection were generally expected from selecting and planting families in the same site.

Abstract

Efektivitas fungi mikoriza arbuskula (FMA) lokal dan ketergantungan jenis tanaman legum terhadap aplikasi FMA ditentukan oleh kecocokan jenis FMA dengan tanaman inang. Penelitian ini bertujuan untuk mengkaji efektivitas FMA lokal terhadap pertumbuhan, biomassa dan serapan hara bibit kayu kuku (Pericopsis mooniana (Thw.) Thw.) umur 5 bulan di rumah kaca. FMA lokal yang diuji diisolasi dari empat rizosfer kayu kuku di Kabupaten Kolaka: FMA-HA (hutan alam Tanggetada), FMA-BJ (hutan tanaman Desa Bali Jaya), FMA-CA (Cagar Alam Lamedai), FMA-Vale (PT. Vale Indonesia Tbk.), dan dua rizosfer yang berasal dari Kota Kendari: FMA-UHO (taman kampus Universitas Halu Oleo), FMA-KG (hutan kota kantor Gubernur Sulawesi Tenggara). Perlakuan tanpa FMA (kontrol) dan FMA eksotik (Mycofer) serta isolat dari Kendari (kdr 03) juga digunakan sebagai pembanding. Rancangan percobaan adalah rancangan acak kelompok dengan 9 perlakuan dan 5 ulangan. Secara umum, aplikasi FMA mampu meningkatkan pertumbuhan dan perbaikan status hara tanaman. FMA- KG dan FMA-UHO mampu meningkatkan pertumbuhan tinggi, diameter, jumlah daun dan jumlah bintil akar bibit kayu kuku. Kedua FMA ini juga mampu meningkatkan berat kering total bibit kayu kuku  masing-masing  sebesar  260%  dan  281%  lebih  tinggi  dibandingkan  kontrol.  Terdapat peningkatan jumlah klorofil total pada bibit kayu kuku yang diberi perlakuan FMA-KG. PerlakuanFMA secara umum tidak memberikan pengaruh yang nyata terhadap kadar C organik dan N total. Walaupun kadar P total, K total, Ca total dan Mg total bibit kayu kuku lebih tinggi pada kontrol, akumulasi hara ditemukan lebih tinggi pada perlakuan FMA. Terdapat hubungan yang kuat dan signifikan antara akumulasi hara dengan biomassa bibit kayu kuku.
