在巴西,亚粘团串珠镰孢(Fusarium moniliforme var.Subglutinans)是菠萝果腐病和菠萝无性繁殖材料的基腐病的病原菌。对于这两种病症来说,在某些大田,危害很大的是果实侵染期,造成产量损失达80％。近几年,用此菌进行温室及大田无伤口接种试验,发现果实侵染率很高。这说明,此菌是通过菠萝花侵入的。然而,从现有资料来看菠萝花作为亚粘团串珠镰孢侵染场所 In Brazil, Fusarium moniliforme var. Subglutinans is the causal agent of pineapple rot and pineapple clonal propagation. For both diseases, in some fields, the most damaging period is the fruit-infested period, resulting in a loss of yield of up to 80%. In recent years, the bacteria used in the greenhouse and field non-wound inoculation test found that fruit infection rate is high. This shows that the bacteria invaded pineapple. However, judging from available data, pineapple flower is used as a site for infection of Fusarium moniliforme
