摘　　要：对来源于中国8省(区)17个油茶品种与炭疽病的抗性关系进行了林间调查,并在室内对其中8个主要油茶品种的果实进行了抗病性研究。结果表明:(1)17个油茶品种在林间自然状态下,对炭疽病的抗病性以攸县油茶、茶梨油茶、徽州小红和徽州大红的抗性较强;舒城大红、浙江红花、罗汉果和软枝油茶抗性中等;其余均为易感病品种。(2)8个不同油茶品种的果皮汁液和果皮培养基所培养的病菌孢子萌发率和菌落生长量也存在着一定的差异。The 3d transition metal (Co,Cu,Zn) doped TiO 2 (abb.M 3d -TiO 2)and CdS Comples for TiO 2 nanoporous film was investigated with photoelectrochemical techniques.The results show that the Conversion efficiency of light to electricity was greatly improved.of all the M 3d -TiO 2 investigated in this paper,however,the photocurrent intensity of Zn 2+ -TiO 2 nanostructured film electrode was higher than that of undoped TiO 2 electrode.It was explained that in the case of this type of photosensitization,the back electron transfer from the TiO 2 conduction band to the solution was refrained,thus the losses of electrons were avoided.
