摘要
对重庆北碚区与四川安岳县柠檬流胶病的研究表明，在２１个菌株中，细菌占９．５２％，真菌占９０．４８％。真菌类主要有镰孢霉、拟茎点霉、腐霉、疫霉和交链孢霉等５属。其中，镰孢霉属的分离频率最高，达３６．８４％，拟茎点霉属为２１．０５％，腐霉属占１５．７９％，疫霉属和交链孢霉属分别占１５．７９％和１０．５３％。因此，镰孢霉。
Lemon ( Citrus limon) is subject to the infection of gummosis, which not only affects its growth but also reduces the quantity and quality of its fruit. The results of Previous investigators differed widely as to its causing agents. In a recent study of gummosis of lemon trees in Beibei and Anyue, China, 21 pathogenic isolates were identified, of which 9.52% were bacteria and 90.48% were fungi. The fungal pathogens included Fusarium Lk. ex Fr., Phomopsis Sacc., Pythium pringsheim, Phytophthora de Bary and Alternaria Ness ex Wallr., accounting for 36.84%, 21.05%, 15.79%, 15.9% and 10.53% of the total. It is therefore concluded that the three genera of Fusarium, Phomopsis and Phythium are chiefly responsible for gummosis on lemon trees in the two regions investigated.
