Abstract In this study, the sound absorption capability of pine ( Pinus densiflora ) cone particles was investigated as an alternative and eco-friendly, sound-absorbing material. The coefficient examined after filling impedance tubes with 4, 6, 8, 10 cm particles. 4 6 thickness categorized 0.5 M class, that 8 classed 0.8 class according to KS F 3503 classification materials. particular, demonst...

The spore of Tricholoma matsutake is considered to be the starting point of the mushroom growth cycle, but the mechanism of mycelial development from the spore stage is not yet clarified. In this study, we tried to measure how far the spores of T. matsutake disperse from a fruiting body located at a Pinus densiflora stand in Korea. We established 16 slide glasses coated with glycerin near a fru...

One of the recommended methods for managing a red pine (Pinus densiflora) forest, where Matsutake mushrooms (Tricholoma matsutake) are cultured, is to remove surface litter layer (A0 layer). In this study, we evaluated effect removing A0 on soil temperature and moisture content. Two study plots, one which had removed other with left intact, were established sloping terrain in P. densiflora fore...

Intraspecific variation in morphometry of pine wood nematodes Bursaphelenchus xylophilus and B. mucronatus in relation to geographical locations in South Korea was investigated using morphometric characters (body length, a, b and c ratio, stylet length, and spicule length for a male nematode and V (%) value for a female nematode). B. xylophilus was isolated from Pinus thunbergii in Jinju (1998)...
