摘要
柠檬流胶病为疫菌、黑蒂腐菌＿２和镰刀菌＿１３种病原菌的混合侵染而致。发生部位以主干居多，主枝极少。而主干上的南、西向较东、北向感染多，差异显著，表明柠檬主干向阳面易遭致日灼而形成伤口感染，有伤口较无伤口易感染。因此，采用主干刷白，隔绝害虫产卵伤害、耕作伤害和日灼为害，是保护主干，防治流胶病的一项有效措施。
The trial showed that the lemon gummosis could resulted from the infections
ofthree-type-mixed pathogens:blight rot,Citrus Diplodia stem-end rot(Diplodia
natalensisP.Evans)No. 2 and Fusarium spp.No. 1.The infection occurred generally on the trunk
andrarely on the main branches.In addition,the south exposure of trunk significantly
sufferedfrom the infection more than west and north exposure. So it is suggested that the
sunscaldsurface of the exposing trunk facilitate the invasion of pathogens.Through the
pathogenicinoculation on the trunk,there was not any infection if the trunk was intact,otherwise,
anyinjuring can cause severe infection,Therefore,trunk white washing and preventing thetrunk
from parasite,culture and sun burn injures are considered as effective measuresavailable to
control the lemon gummosis.
