Abstract

Research of loamy and soil influence on growth ofagroforestry sengon and nilam was conducted in private forestland in Sukamulih Vilage, Sariwangi Sub-Distric, Tasikmalaya District on November 2004 to November 2006. Two kinds ofsoil sample were taken from the upper and down part ofprivate forestland area. The research was conducted by analizing those soil samples in the laboratory. The result shows that the private forest land has loamy sand soil its texture with low rate offerlility. The planting activity was conducted in 3 blocks ofplanting area and 48 sengon were ptanted each block. The diameter and height ofsengon tree in loamy sand soil have good rate ofgrowth, which is 7.28 in of height and 9.48 of diameter in 24 months old. Meanwhile, nilam has 64.32 cm of height, 141.68 branches and 2.9 ofwet weight in 3 months old after cutting in the monoculture planting puttern. The loamy sond soil texture gives the positive influence on sengon and nilam growth. Therefore sengon and are potentially to developedin private forest development and degraded forestland rehabilitation.

Abstract

The objective of the research to find out the influence of michoriza, enrichmeni organic fertilizer, and wood vinegar combination on growth of G. arboreaseedling. The research was conducted in the. nursery, area of Foresny Research Instiude on November 2006 to January 2007. The research used the Complete Random Design (CRD) with 6 (six) treatments. The research shows that the michoriza, enrichmentorganicfertilizer and wood vinegar combination produces 50.87 cmof the best growth of tree's height. The influence organic fertifizer in treatment combination (M1N0C0vs M1N1C0) has a significant result on growth G. arborea seedling's height. The treatment combination MINICO (44,63 cm) showed a better result than the M1N0C0 (35,55 cm). The influence of wood vinegar treatment combination has not significant result on growth G. arborea seedling's height.

Abstract

Hybridization Morus sp, has given a significant impact increasing leaf productivity. There ore some good performaning Morus hybrids such as M. nigra x M. indica (M.N1). M. australis x M. indica (M.AsI). and M. alba var kanva which might be good forfeeding materials of silkworm. However, it is necessariy to test the leafsuitability asfeeding material to the quality of cocoon that will be produced. For that purpose one set offeeding experimentation using Bombyx mori L, (bivoltine silkworm egg F1 China and Japan double crossed with the code C 301) and three kinds of mulberry was established. The researeh located in Grogolan village, with 500 m asl. altitude, 2.500 mm - 3.000 mm rain per year, 75% relative humidity and 25° .3,0°C temperature. The study was arranged Randomized Completely Design with three replications. The result showed that the effects of mulberry leaves were non signifcant for the survival percentage of silkvorm instar I-III, the survival percentage of silkworm instar IV-V, weight of cocoon, weight of cocoon shell, cocoon shell percentage, length of filament, weight of filament, filament percentage and reelability of cocoon, There were significant differences in rendement ofrearing. In general, leaves those three hybrids are suitable for silkwonn feeding.

Abstract

Pulai (Alstonia seholaris (L.) R. Br.) is species of high economic value and has been intensive utilization. Conservation effort and breeding strategies should be carried out prevent extinetion. The study ofgenetic diversity using RAPD marker can asses polymorphism through bandingpatterns from amplified DNA. The aims of this research are to estimate genetic diversity within and among pulai populations, investigate distribution ofgenetic diversity, and genetic relationship between pulai provenance. Leaf samples were taken from eighteen pulai provenances in Indonesia, namely Lubuk Linggau, Pendopo, Benakat, Banten, Bantul, Gunungkidul, Bali, Purworejo, Perawang, Mataram, Sumbawa, Kupang, Timor Tengah Selatan, Agam, Gowa, Makassar, and Kendari. Genetic diversity was analyzed using 23 primers and produced 114 polymorphic loci. Results showed that the distribution ofgenetic diversity within provenance was higher than that of among provenance. Cluster analysis revealed that the eighteen provenances was into two major groups. The first group consisted of provertance Lubuk Linggau, Banten and Pendopo. The second group of provenance of Benakat, Perawang, Agam, Solok, Bali, Kendari, Bantul, Purworejo, Gunungkidul, Mataram, Sumbawa, Gowa, Makassar, Kupang, and Timor Tengah Selatan. In general, the genefic relationships among eighteen provenances donot show the relation between genetic diversity and geographic distribution of pulai provenance.

Abstract

The objective of the study was to determine the effect of arbuscular mycorrhizal fungi collected from soil of teak plantation forest on the growth of teak seedling related to mycorrhizal association development. The study utilized the complete randomized design with three levels of inoculant’s factor, consisting of control (uninoculated), inoculation with Gigaspara spores and inoculation with Glomus spores inoctilated, with ten replications. Spores isolated originated from soil of teakplantation forest in Tangen, Surakarta. The planting medium was a mixture soil sand at 1:1 (v/v) sterilized prior to be used. NPK mixed ferfilizer was applied at amount 0,0625 gr per seeadling mixed in to the planting medium. Measurements were conducted during a five month period. The data were analyzed using the Analysis ofVariance method and differences among treaments analyzed usfing the Duncan’sMultiple Range Test at the 5% ievel of significance. The results showed that inoculationwith the arbuscular mycorrhizail fungi increased teak seedling growth, with Gigaspora sp inoculation giving the highest growth. The uptakes of N, P, K and Ca were increased by both Gigaspora sp and Glomus sp inoculations. The increased seedling growth, was accompanied by large increases in infection percentage as well as sporulation. The highest infection and sporulation  were found with Gigaspora sp inoculation. These results showed that in the soil ofteak plantation forest in Tangen of the grumusol type, relatively low NPK fertilization (0,0625 gr per seedling) and inoculadon with spores ofarbuscular mycorrhizal fungi improved teak seedling growth, inereased nutrient uptake, as well as improved mycorrhizal association development in teak seedlings.
