The impacts of white-rot fungi on altering wood chemistry have been studied mostly in vitro. However, in vivo approaches may enable better assessment of the nature of interactions between saprotrophic fungi and host tree in nature. Hence, decayed and sound wood samples were collected from a naturally infected tree (Carpinus betulus L.). Fruiting bodies of the white rot fungus Trametes versicolo...

Proposed is a method to investigate degradation of lignocelluloses by pure cultures of basidiomycetes using preserving jars with vermiculite as reservoir for water and nutrients. Bamboo samples of Gigantochloa atroviolacea and Phyllostachys pubescens and wood samples of Fagus sylvatica and Pinus sylvestris were inoculated with the brown-rot fungus Coniophora puteana and the white-rot fungus Sch...

ENTOMOLOGY I MR. SANCHEZ NAVARETTE : NO. DR. WIEHE : DO not 'dead hearts' result in some of the drier parts of Mauritius ? MR. WILLIAMS: When there are several borers near the top of a stalk, the top may die. This is different from a 'dead heart'. MR. SANCHEZ NAVARETTE : IS it easy to find several larvae in a single stalk ? MR. WILLIAMS: NO. We usually find one or two. D. W. FEWKES (Trinidad) :...

tobacco is planted extensively in golestan province and high volume of its stem wastes remained without using and it is burned. as a useful purpose of these wastes and to reduce the environmental problems, in this the mechanical properties of polypropylene composites reinforced with tobacco stalk flour were studied. for this purpose, the tobacco stalk flour as the reinforcement, in three levels...
