The Action Difference of Lasiodiplodia theobromae on Infecting and Dyeing Poplar Wood in Spatial Growth

Many factors affect the driving force of fungal growth and secretion. To compare differences Lasiodiplodia theobromae infected poplar wood, changes physical chemical properties vertically horizontally wood before after dyeing were analyzed, infection characteristics studied in this paper. The horizontal was more effective than vertical terms depth, color microscopic hyphal invasion. mycelium first intruded into earlywood tissue began to secrete a large amount pigment twenty days. crystallinity decreased slightly, difference weight loss rate negligible. initial contact angle dyed specimen on increased drastically distilled water, but there almost no between varnish natural coating. efficient had higher depth better induction effect, which is crucial future microbial dyeing.
