23种广东常见阔叶树材的耐磨性质

本文报导23种广东常见阔叶树材的耐磨性试验结果,并对耐磨性与木材密度、硬度的关系及木材耐磨性各向异性问题作了讨论。     

超临界CO_2流体处理工艺对木材渗透性的影响

以苯—乙醇为夹带剂,研究超临界CO2流体不同处理压力、温度、时间对福建产杉木、马尾松、檫木木材渗透性的影响。结果表明,在35 MPa内,处理压力的增大有利于3种木材渗透性的提高;杉木在处理温度为40℃时,渗透性的变化率达到最大,为493%,马尾松和檫木在处理温度为45℃时,渗透性的变化率达到最大,分别为479%和349%;较佳的处理时间为30 min。     

火炬松短周期工业材不同高度上干缩性能的研究

对湖南同一立地指数（１８）下，５株１７．５年生的火炬松（ＰｉｎａｓｔａｅｄａＬ．）短周期工业材１．３，３．６，５．６，７．６，９．６ｍ５个高度的木材干缩系数、基本密度、生长轮宽度、晚材率和微纤丝角度，按生长轮取样，进行了测量和统计分析．结果表明，弦向、径向、体积干缩系数和干缩比，在树于５个高度之间的差异，均达到了显著水平；各高度干缩系数与生长轮的年龄（离髓心的距离）以及与上述各主要构造因子之间呈显著的线性相关，且相关度度随树干高度的增加而减弱．     

变叶海棠种群多样性的形成与分化研究

 采用杂种指数和形象化散点图法, 探明了变叶海棠以兼性无融合生殖方式与陇东海棠和花叶海棠产生渗入杂交变异, 又以无融合生殖方式保持新产生变异的遗传, 经过数千万年的世代繁衍,形成现今这样极其复杂多样的渗入杂交群体, 该群体为3 个种的杂交复合体。由于杂种的全部或部分能育子代中发生的基因重组和增加基因的突变, 丰富了物种的基因库, 从而深入的揭示了变叶海棠具有多种高抗性的遗传机理。在变叶海棠居群内保护或栽植适量的陇东海棠和花叶海棠, 对于保持和促进变叶海棠多样性的形成与分化具有重要意义。     

Fungi associated with esca disease in grapevine

Cross sections of woody stems of 309 diseased grapevines collected in France showed two kinds of necrosis typical of esca: a) A central light-colored necrosis of soft consistency, consisting of three zones, preceded by a centrally discolored wood, and b) a sectorial light-colored necrosis composed of two zones preceded by a sectorial brown necrosis. Isolations showed that different microflora was associated with each necrosis. Phaeoacremonium aleophilum and Phaeoacremonium chlamydosporum occurred in the discolored wood and the zones bordering the central decayed wood. Eutypa lata was the main fungus isolated from sectorial brown necrosis and the zones adjoining the decay wood. Phellinus punctatus was isolated from the sectorial and central decayed wood. Stereum hirsutum was present in decayed wood of 15 grapevines with esca symptoms not inhabited by P. punctatus. Wood decay tests and pathogenicity tests showed that S. hirsutum and P. punctatus were responsible for the decayed wood. Phaeoacremonium chlamydosporum and S. hirsutum produced a centrally discolored wood similar to that found in esca-affected vines. Phaeoacremonium aleophilum caused a sectorial brown necrosis of soft texture. From these studies, it was found that esca is a complex disease involving several microorganisms whose role in the process leading to wood degradation is discussed.     

木质包装中黄斑星天牛微波处理初探

为了探索微波处理作为木质包装替代处理方法的可能性,对不同规格和含水量的杨树木块进行微波处理试验,结果表明:频率为2450MHz的微波能够穿透厚度为10cm的杨树木材;当微波功率为900W时,规格为10cm×10cm×10cm和10cm×10cm×2.5cm的新木块中黄斑星天牛(Anoplophora nobolis)幼虫完全死亡所需时间分别为5min和2min;而干木块中则仅需3min和30s.对微波处理引起木材温度变化和水分损失以及天牛幼虫的水分损失进行了初步研究.     

The evaluation of the synergetic degree of ecology economy society system of China forestry during the last decade

Ecological ravages, environmental pollution, and the developmental problems of regional ecology, economy, and society are not geographical restrictions. The synergistic development of the ecology-economy-society system in forestry was quantitatively assessed by system theory and synergistic dynamic models, illustration of the metering principle and corresponding theory, assessing and quantizing synergistic development status of ecology-economy-society system, and the orderliness of the subsystem of the last decade. The orderliness of the ecology and ecological subsystems developed unstably with an increasing trend. The eco-environment construction and eco-conservation achievement of forestry in China are effective and need to be maintained. The industry structure should be improved to promote the growth of the forestry economy. The society subsystem development is increasing but is not at a high level, which indicates that the public demand to ecological service was not satisfied. The theoretical analysis and numerical examples show that the development of the forestry system has a good development state. The synergy changes of forestry system in the 0 to 0.951 range, which is in the intermediate degree of synergy during this period. It still needs much improvement on efficiency of synergy. The orderliness and the relationship among the subsystems of forestry should be improved in future.
