“…A major species in the Indonesian timber estate is Acacia mangium (Yamashita et al 2008, Leksono et al 2008, Rokeya et al 2010, Tarigan et al 2011 which is mainly used for pulp, paper and other wood products (Beadle et al 2007, Kim et al 2009, Le Roux et al 2009, Yong et al 2011, Asmah et al 2013. Principal characteristics of wood fibre that influence the yield and paper quality are length, wall thickness, chemical composition and microfibril angle (MFA) (Yahya et al 2010, Pirralho et al 2014.…”

“…Information on the effects of planting density and thinning on C sequestration by multipurpose tree species is scarce (Jandl et al, 2007) but on conifers particularly in Europe are available (Marziliano et al, 2015;Coletta et al, 2016); similarly, thinning and pruning interaction may influence growth and development of tree by affecting resources availability (Beadle et al, 2007). However, information on the impact of various cutting management levels in combination with high density plantation (HDP) on the biomass and carbon stock of woody perennial based land use systems is still unavailable.…”

Abstract. Tree growth and productivity are influenced by silvicultural strategies such as tree density and cutting management, which determine the potential of tree species to store carbon in the vegetation. A field experiment was conducted at Vivekananda Institute of Hill Agriculture, Almora, India in a 30-yearold Quercus leucotrichophora to evaluate the changes in vegetation carbon pools as a function of four cutting management (1m, 2m, local practice, and above 1/3 rd part undisturbed), under high density plantation (1.0m × 1.0m). Tree cutting management significantly (<0.01) influenced the carbon stocks of Q. leucotrichophora trees. Total vegetation (aboveground + below ground) carbon stock was highest for the above 1/3 rd part undisturbed (356.9 Mg ha -1 ) and lowest in the cutting at 1m (86.7 Mg ha -1 ). Overall, less disturbance to stands promote carbon storage, but intense cutting management (e.g., cutting at 1m) may adversely affect tree growth and productivity, reducing vegetation carbon pools. Cutting management effects are very much visible on carbon stock of Q. leucotrichophora under high density plantation. By extension, stand cutting exerts negative or positive feedbacks on biomass accretion, which may also influence the amount of carbon sequestered by the trees.

ABSTRAKInformasi keragaman genetik dari satu generasi ke generasi selanjutnya merupakan faktor penting untuk pengelolaan dan konservasi genetik kebun benih. Tujuan dari penelitian ini adalah untuk mengevaluasi tingkat keragaman genetik tetua sebagai generasi pertama (F1) dan anakannya (F2) dari kebun benih Akasia mangium yang ada di kebun benih semai Grup D (AM004) di Sumatera Selatan. Analisis dilakukan terhadap 251 tetua dan ± 200 biji dari 10 pohon induk. Analisis menggunakan 12 penanda mikrosatelit menunjukkan bahwa rata-rata jumlah alel yang terdeteksi (A) dari semua tetua dan anakannya adalah 8,23 dan 7.08. Secara umum, tingkat keragaman genetik tetua dan anakan tidak berbeda (He=0.609 untuk tetua dan He=0.606 untuk anakan). Penelitian ini mendeteksi keberadaan alel baru pada anakan. Kondisi ini menunjukkan kemungkinan adanya kontaminasi serbuk sari dari luar kebun benih.Kata kunci: Keragaman genetik, kebun benih semai Sumatera Selatan, tetua, anakan, penanda mikrosatelit ABSTRACT Information on genetic diversity from one generation to its next generation is an important factor for management and conservation in a seed orchard. The purpose of this study was to evaluate the level of genetic diversity of parental as the first generation (F1) and offspring (F2) of Acacia mangium in the
