  rot
Eucalyptus chemithermomechanical pulp (CTMP) was modified with the white-rot fungus 19-6 in a stationary culture condition.
      
Different factors that influence the effect of white-rot fungus treatment, including additional nutrition, pH value, temperature, treatment time and oxygen input were investigated.
      
The results show that the energy consumption of post refining of CTMP treated by white-rot fungus 19-6 was lower than that of untreated pulp and the strength properties also obviously improved.
      
Unfortunately, the treatment with white-rot fungus substantially decreased all optical properties except for opacity, which was essentially unchanged.
      
Influence of glucose feeding on the ligninolytic enzyme production of the white-rot fungus Phanerochaete chrysosporium

It is suggested that Dechang county area is the ancient natural distribu-tion region of the species.

Natural resistance of wood from differnt tree species to microbial deterioration differs considerably. Individual trees of the same species may also vary a great deal in decay resistance. Natural durability varies within the same tree too, especially in species with very durable heartwood. In the durable species, decay resistance decreases incessantly from the outer heartwood to the pith. Toxic extractive substances deposited during the formation of the heartwood are the principal source of decay resistance....

Natural resistance of wood from differnt tree species to microbial deterioration differs considerably. Individual trees of the same species may also vary a great deal in decay resistance. Natural durability varies within the same tree too, especially in species with very durable heartwood. In the durable species, decay resistance decreases incessantly from the outer heartwood to the pith. Toxic extractive substances deposited during the formation of the heartwood are the principal source of decay resistance. Most of the heartwood extractives known to inhibit decay are phenols. Carvacrol, 2-thujaplicin, quercetin pinosyluin, and tannins all seem to contribute to decay resistance, other mechanisms of natural durability of wood, such as the lignification of wood cell walls, crystallinity of the cellulose, depletion of reserve food materials, higher moisture rcquirments for wood-inhabiting fungi, and different resistance of the wood structure to white-rot and brown-rot fungi arc also discussed, in this paper.

不同树种的木材对微生物分解的天然抵抗力是不同的,同一树种的不同个体的耐腐力亦有很大的不同,甚至同一棵树的不同部位其耐腐性也会有变化,特别是对于那些具有很耐腐心材的树种。在耐腐树种中,其耐腐力从心材的外缘到髓芯逐渐降低。在心材形成过程中积聚起来的毒性提取物是耐腐力的主要来源。已知对腐朽有抑制作用的大多数心材提取物是酚类化合物。香芹酚、(艹守)侧素、栎精,3,5-二羟苯乙烯和单宁都可能对耐腐性起作用。本文还论述了木材耐腐性的其它一些因素,例如木材细胞壁的木质化,纤维素的结晶度,贮存食物的枯竭,木材水份的含量以及木材结构对白腐菌和褐腐菌的不同抵抗力等。

The present paper is an opinion on the flora of the woody plants in Mt. Wuyi in Yanshan County, Jiangxi Province. In the area there are 608 species and 33 varieties (incl. form species and subspecies), belonging to 100 families and 248 genera. Among them 1 genus and 18 species and 2 varietis are recorded for the first time from the province and 19 species are the specially protected plants of our country.Mts. Wuyi Winds in and out from north to south. The area is situated at the northern part of the rots. —latitude 27°45′—58′ N.longitude 117°35′—52′ E..The summit, by the name of Huang—Gang—shan, is the highest (2158 m. above the sea levrl )in eastern China. According to geomorphology the area belongs to the region of the medium height mountain. There are a steep and deep cutting hill and a warm and humid environment. Because of the rich botanical and animal resources the area is a very good place for studying the vegetation of the Southeast Continent.It is pointed out that the zonal vegetional form is laurilignosa, which consists of chiefly the evergreen plants of Fagaceae, and Lauraceae, Theaceae, Aquifoliaceae, Ericaceae, Symplocaceae etc. and with the floral feature of the woody plants as follows.The flora of the woody plants is not very rich, but it is very complex and there are a lot of ancient, precious, relic and rare species. It shows us the character of the flora of the woody plants of the typical "Central Subtropical Region".It is described that the perpendicular distribution is very obviOus, various communities are discovered at different elevations and environments.

根据作者近六个月采集的1100余号标本以及前人采集的数百号标本的研究结果,铅山武夷山有木本植物608种33变种(除栽培种),隶属100科248属,其中1属18种2变种为江西省分布新记录。本区木本植物地理成份复杂,古老和珍稀植物较多,较好地反映了典型的中亚热带东部地区木本植物区系特点。
