| 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. |

| Abstract: |
| In this paper the resistance to Colletotrichum gloeosporioides of 17 oil tea plant cultivars from 8 provinces of south China were investigated in natural forests, and some biological characters of C. gloeosporioides on the 8 main cultivars were studied in laboratory furtherly. The results showed that:(1)Camelliae yansienensis, C.octopetala, C.oleifera.Abel var.Huizhou-Xiaohong,C.oleifera Abel var. Huizhou-dahong, have higher resistance to the Colletotrichum gloeosporides among 17 cultivars;C.oleifera.Abel var. Shucheng-Dahong, C.chekiagoleosa, C.oleifera.Abel var. Luohanguo,C.oleifera Abel var. Ruangzhi have certain resistance; and the remainders were susceptible.(2) there are siginifant differences for the rates of spore germination and the growth of hypha by using juice and peel culture media of 8 cultivars. |
