Morphological and molecular features of stain fungi infecting rubberwood (Hevea brasiliensis)

Abstract. Nandika D, Arinana, Salman ABA, Putri JY. 2021. Morphological and molecular features of stain fungi infecting rubberwood (Hevea brasiliensis). Biodiversitas 22: 5408-5416. In the southeast Asia region, particularly Indonesia, Thailand, Malaysia, brasiliensis Muell. Arg.) has been widely used as a raw material in various industries furniture manufacturing. However, is highly susceptible to fungal attack due its lack heartwood formation. A laboratory study was conducted investigate morphological rubberwood. total five isolates belonging three genera were identified based on internal transcribed spacer (ITS) features. All belong Order Eurotiales with each genus being Paecilomyces, Aspergillus, Penicillium. The highest growth rate wood samples shown by Aspergillus chevalieri section Paecilomyces maximus or P. formosus values 86.57% 86.22%, respectively. caused varied level discoloration dark grayish very more frequent color found. Quantitatively, A. (?E = 27.60) 16.69). These species can be considered newly recorded Indonesia. addition, these two worst.
