As part of multiple-population breeding scheme using sub-lining system, a composite seedling seed orchard of was established at Central Java, Indonesia. The orchard comprises a combination of the best 40 plus tree families selected from four sub-lines in the first-generation of Acacia mangium progeny trial. The design of orchard is randomized complete block laid-out as four line tree-plot of six replications with a spacing of 2 x 4 meter. Variation among sub-lines and families within sub-line, and genetic parameters for height, dbh and volume were investigated at age of 24 months. The aim of t

Asymbiotic germination of immature seeds of orchids represents a valuable method for large-scale seedling production, addressing both commercial demand and the conservation of rare and endangered species. In this study, we explored the efficacy of three low-cost substrates: Polyurethane foam (PUF), Coconut husk chips (CHC), and Tree Leaf litter (TLL), as substitutes for the expensive agar-gelled medium in the <em>in vitro</em> seedling culture of three commercially important orchid species, namely, <em>Paphiopedilum fairrieanum</em> (Lindl.)

A breeding program to enhance the economics of producing essential oil (Australian tea tree oil) from Melaleuca alternifolia plantations in eastern Australia by improving oil yields and oil quality commenced in 1993. This paper reports the results of the first (2003) and second harvests (2004) of a yield trial established by the program in 2002. The trial compares the performance of three grades of seed (clonal seed orchard, first generation seedling seed orchard and selected provenance) released to the industry by the breeding program against an unimproved seedlot (industry standard).

Phenotypic traits (thousand seed weight and plumpness, etc.), germination characteristics (germination rate and nursery germination rate, etc.), growth traits (seedling height, basal diameter, root length, etc.) and photosynthetic parameters of 8 superior families and 3 controls (seed orchard, seed production stand and planted forest) were measured and analyzed to determine the difference of seed germination and seedling growth among Larix principis-rupprechtii families. Results showed that families 7-46, 8-74 and 1-30 performed excellent in aspects of germination index, nursery germination ra

Abstract Development of the hybridization between two different species of Acacia mangium and Acacia auriculiformis in Indonesia started in 2009 by establishing an open-pollinated orchard to produce the natural Acacia hybrid seed in Wonogiri District, Central Java Province. The design of the orchard was an alternate row between A. mangium and A. auriculiformis with a spacing of 5 × 5 meters. The orchard produced putative Acacia hybrid seeds firstly in 2013. Based on flowering synchronization between the two species, seeds from 38 sample trees of A. mangium were taken to identify their characte

There are two possibilities on open pollination: cross pollination and self pollination. This research was aimed to identify cross pollination potential within and among provenance, and to determine the flowering behavior of each provenance in seedling seed orchard of cajuputi at Paliyan, Gunungkidul. The research was conducted based on flowering phenology (start of flowering, end of flowering and duration of flowering in one period) for all flowering trees during two flowering periods. The result showed that there was high crossing potential in seedling seed orchard of cajuputi based on flowe

Abstract A greenhouse inoculation study compared resistance to fusiform rust (Cronartium quercuum (Berk.) Miyabe ex Shirai f. sp. fusiforme) of loblolly pine (Pinus taeda L.) seedlings derived from bulk seed produced in 4 rust-resistant seed orchards, 1 rust-resistant geographic seed source (Livingston Parish, LA), and a control treatment of improved loblolly from a first-generation production orchard. The rust-resistant orchards included 2 forest industry orchards developed from the most rust-resistant clones available within a tree improvement cooperative (1st generation), and both a clonal

Orientador: Mario Luiz Teixeira de Moraes<br>Resumo: O êxito dos programas de melhoramento florestal requer que a predição do progresso genético seja proporcional ao progresso genético real. Para isso, é possível unir a genética quantitativa com ferramentas moleculares, que permitem estimar parâmetros com maior acuidade para seleção. O objetivo foi verificar a diversidade genética, o sistema de reprodução e as relações de parentesco em populações de polinização aberta de Eucalyptus urophylla, para selecionar cruzamentos e genitores.

AbstractThe target of the Indonesian government was to restore at least 2 million ha of degraded peatlands by 2020. This can be achieved by applying three approaches: rewetting, revegetation, and revitalization of the community. In revegetation, the use of native tree species is recommended in the technical guidelines for peatland restoration. The interest in using native plant species for ecosystem restoration, particularly for peatland restoration, is increasing significantly. The native species may adapt well to the environment and usually correspond with the people’s preference. An importa
