The Potential Risk of Tree Regeneration Failure in Species-Rich Taba Penanjung Lowland Rainforest, Bengkulu, Indonesia
BIODIVERSITAS ISSN: 1412-033X Volume 19, Number 5, September 2018 E-ISSN: 2085-4722 Pages: 1891-1901 DOI: 10.13057/biodiv/d190541 The potential risk of tree regeneration failure in species-rich Taba Penanjung lowland rainforest, Bengkulu, Indonesia AGUS SUSATYA Department of Forestry, Faculty of Agriculture, Universitas Bengkulu. Jl. WR Supratman, Kota Bengkulu 38371A, Bengkulu, Indonesia. Tel./fax. +62- 736-21170, email: [email protected] Manuscript received: 28 May 2018. Revision accepted: 22 September 2018. Abstract. Susatya A. 2018. The potential risk of tree regeneration failure in species-rich Taba Penanjung lowland rainforest, Bengkulu, Indonesia. Biodiversitas 19: 1891-1901. Tropical lowland rain forest is recognized by its high species richness with very few trees per species. It is also known for having tendency to outcrossing of its species with different floral sexualities, which requires the synchronization between flowering of its trees and the presence of pollinators. Such ecological attributes raise possible constraints for the forest trees to regenerate. The objective of the study was to assess the potential risk of failed regeneration for each tree species of the forest. Each of species with dbh of more than 5 cm in a one-ha plot was collected, identified, and its ecological criteria, including rarity, floral sexuality, seed size, and flowering phenology were determined. The potential risk of the failure of regeneration was calculated by summing all scores from Analytical Hierarchical Process of the criteria. The results indicated that the forest consisted of 118 species belonging to 69 genera and 37 families. Rare species accounted to 52.10% of the total species. -

Bioassay- guided fractionation led to the isolation of three active flavaglines. These were elucidated and identified by using spectroscopic methods (NMR, UV and IR) as aglafoline and didesmethylrocaglamide from A. argentea, and rocaglaol from A. oligophylla. A 96-well microbioassay revealed that rocaglaol produced high growth inhibition of Botrytis cinerea, Colletotrichum gloeosporioides, and Pestalotiopsis sp. With EC50 values at 0.05 μg/mL against Pestalotiopsis sp., 1.2 μg/mL against Botrytis cinerea, and 52 μg/mL against Colletrotrichum gloeosporioides.

Muellner1, H. Greger2, C.M.

We performed maximum parsimony, maxi- Aglaia mum likelihood and Bayesian analyses (nuclear ITS rDNA) to estimate genetic relations among samples of Aglaia biogeography elaeagnoidea, and their phylogenetic position within Aglaia (more than 120 species in Indomalesia, Australasia, and dispersal the Pacific islands). Based on 90 accessions of Melioideae (ingroup) and four taxa of Cedreloideae (outgroup), this internal transcribed spacer (ITS) study 1) provides a first assessment of the genetic diversity of Aglaia elaeagnoidea; 2) investigates the geographic Meliaceae structure of the data in selected eastern and western regions of its distribution; and 3) suggests that Australia has molecular clock been colonized only recently by A. elaeagnoidea and other species within the genus (Miocene/Pliocene boundary Sapindales to Pliocene). Based on DNA data, morphology and additional evidence derived from biogenetic trends (secondary metabolites), the name Aglaia roxburghiana could be reinstated for specimens from the western end (India, Sri Lanka), but we have no data yet to indicate definitely where A. roxburghiana ends and A. elaeagnoidea begins either morphologically or geographically. Viewed in a more general context, Aglaieae are an ideal model group for obtaining more insights into the origin and evolution of Indomalesian and Australian biotas. -

Disetujui: 10 Mei 2006. ABSTRACT The objectives of this research were to determine the chemical components and the peroxide values of three Aglaia species (A. argentea Blume, A. silvestria (M. Roemer) Merr and A. tomentosa Teijsm & Binn). Phytochemical screening was done by Cuiley method, while peroxide values were determined by iodometri-titration on methanol, hexane, chloroform and ethyl acetate extracts. The result of phytochemical screening indicated that all of Aglaia species tested (three species) contained sterol and triterpenoids, base alkaloid, reduction sugar, and anthrasenoid while other components present only in one or two species of Aglaia. Peroxide values of the tested extracts were higher than that of vitamin E (40.996 mili-equivalent/1000 g samples) as a standard reductor, except the peroxide value of chloroform extract of A. tomentosa (41.078 milli-equivalent/ 1000 g sample). It can be concluded that A. tomentosa chloroform extract might had similar ability with vitamin E in preventing or delaying oxidation process. A. tomentosa chloroform extract acted as reductor. © 2006 Jurusan Biologi FMIPA UNS Surakarta Key words: Aglaia spp., chemical compounds, peroxide value. -

The cytotoxic activity of bark extracts from a Philippine native tree, Aglaia loheri, were tested against human colorectal cancer cell line HCT116 using 3-(4,5-dimethyl2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay. The methanolic crude extract was subjected to a bioassay guided solvent partitioning and fractionation by vacuum liquid chromatography (VLC) and gravity column chromatography (GCC). The apoptotic effect of the most active fraction was investigated using JC-1 assay to determine mitochondrial membrane alteration and TUNEL assay to detect DNA fragmentation. A. loheri crude extract demonstrated very high cytotoxicity against HCT116 with IC50 value of 0.49±0.07µg/mL. The hexane (ALBH) and ethyl acetate (ALBEA) partitions and most of the VLC and GCC fractions showed high to moderate cytotoxicity. -
INTRODUCTION Aglaia Lour. Is the Largest Genus in the Family

The wood anatomical features of 13 species of Aglaia from Thailand were studied and described to aid microscopic wood identifi cation. Diagnostic features include the width of multiseriate rays, crystals, the type of paratracheal parenchyma and ray cell composition. Wood specifi c gravity was studied in relationship with the wood anatomy. Our results showed a high negative correlation between wood specifi c gravity and fi bre lumen diameter, but no signifi cant relationships between wood specifi c gravity and features of rays and axial parenchyma.
