The Influence of Pruning Shoot Age on the Growth of Hopea odorata Roxb. Cutting

A study was conducted on the impact of forest clearance on discharge from newly established Hopea odorata plantations catchment (14.4 ha). The stands were two years old when this study commenced in year 2006 and the data collection was carried out for two years. The forested catchment (C3) was clear-cut during the preparation of the forest plantation and catchment C1 was left undisturbed. Discharge and rainfall were measured continuously for two years. The discharge measured from years 1997 to 2003 was used also to determine the water yield before and after forest clear-cut. This study showed that the plantation catchment is more responsive to storm with higher total water yield than in the forested catchment. The effect of forest clear cutting to discharge was clearly shown by the increment in the amount following the clear-cut activities and time taken for the recovery of the discharge back to its original state was almost three years. The peak discharge in C3 also was affected in which the biggest change was obtained during the forest clear-cutting period compared with during calibration and after clearing periods. This study is useful as basis for improving the existing guidelines on forest plantation establishment.

Abstract. Haneda NF, Furqan M, Suheri M. 2020. Stem borer insects on Hopea odorata in Bogor, West Java, Indonesia. Biodiversitas 21: 5308-5316. Hopea odorata Roxb. locally known as “merawan”, is a dipterocarp species that has the potentials to be developed for plantation forestry. Nonetheless, anecdotal evidence in Bogor, West Java, Indonesia, suggested that the trees suffered serious attacks caused by stem borer insects, causing defoliation of the crown and leading to stunted growth and death. This phenomenon suggests a more systematic investigation. The objectives of this research were: (i) to identify the species of stem borer which attacked H. odorata; (ii) to investigate the types and forms of the damage of H. odorata tree due to stem borer attack; and (iii) to study the effects of stem borer attack on the tree and wood of H. odorata. The results showed that all species of stem borer insects belong to Coleoptera, namely as Xyleborus perforans (Scolytidae), Xyleborinus perexiguus (Scolytidae), Platypus parallelus (Platypodidae), Belionota prasina (Buprestidae), Curculionid beetle, and Tenebrionid beetle. The number of boring holes on a single tree was 1932 holes, of which 98.6% caused by ambrosia beetles: Xyleborus perforans (1426 holes, 73.8%), Xyleborinus perexiguus (457 holes, 23.7%), and Platypus parallelus (21 holes, 1.1%). The length of boring tunnel at cross-section ranged between 2-35 cm and at longitudinal section ranged between 4-6 cm. The number of boring holes decreased along with the increasing height of tree stem. The patterns of boring tunnel at stem cross-section were branching (X. perforans, P. parallelus); encircled (X. perforans), black stains along their wall (X. perexiguus, X. perforans, P. parallelus).

Regenerasi alami tanaman dipterokarpa di Hutan Cigerendeng adalah bentuk usaha tumbuhan menjaga kelangsungan hidup agar tidak mengalami kepunahan. Penelitian ini bertujuan untuk mengetahui populasi dan nilai ekonomi sediaan anakan dipterokarpa pada tingkat semai dan pancang. Metode penelitian yang digunakan adalah analisis vegetasi dengan plot berpetak ukuran 2x2 m untuk anakan semai dan 5x5 m untuk anakan pancang yang diletakkan pada 18 petak hutan. Data dianalisis untuk menghitung jumlah individu, jumlah jenis, kerapatan, frekwensi dan nilai penting (INP) serta potensi anakan. Selain itu dianalisis pula pola sebaran masing-masing jenis dipterokarpaceae. Nilai ekonomi anakan dihitung dengan pendekatan nilai rente ekonomi. Hasil analisis vegetasi menunjukkan bahwa di Hutan Cigerendeng terdapat 5 jenis anakan semai dan pancang (Hopea mengarawan Miq., Hopea odorata Korth., Hopea sangal Roxb., Shorea ovalis Bl., Shorea selanica Bl. dan tambahan 1 jenis anakan Hopea bancana tingkat pancang. Jenis anakan dominan yaitu Hopea mengarawan Miq. dengan kerapatan hingga 153.000 batang/ha dan INP (149,2) pada tingkat semai dan 6700 batang/ha dan INP (151,5) untuk tingkat pancang. Potensi anakan jenis dipterokarpa di Hutan Cigerendeng mencapai 1.085.166 batang untuk anakan tingkat semai dan 48.355 batang anakan tingkat pancang dengan total nilai ekonomi mencapai Rp. 166.360.000,-.

AbstractBackgroundThe current study evaluates the analgesic effect of different extracts ofHopea odorataleaves in mice followed by molecular docking and absorption, distribution, metabolism, excretion, and toxicity (ADME/T) analysis of isolated compounds derived from the plant with the COX-1 enzyme.MethodsIn the present study, the dried leaves ofH. odoratawere subjected to extraction using methanol, ethanol, and water.In vivoanalgesic activity was evaluated by using the acetic acid-induced writhing test and formalin-induced paw licking test, andin silicomolecular docking and ADME/T study were performed using Schrödinger Maestro (version 11.1) and online-based tools, respectively, on eight isolated compounds.ResultsThe results showed that the methanolic extract of leaves has highest significant dose-dependent analgesic activity at both 200 and 400 mg/kg followed by ethanolic extract of leaves. Among all the compounds, ampelopsin showed the best docking score of −7.055, ensuring strong binding affinity between the ligand and the receptor, and ADME/T analysis using Web-based tools ensures the compound has not violated Lipinski’s rule of five indicating its safety consumption.ConclusionsThe result confirms the analgesic activity ofH. odorataleaves in bothin vivoandin silicoassays. The data support ampelopsin to be a potent analgesic compound worthy of future clinical trials and its “drug-likeliness”
