摘　　要：采前低温可诱发菠萝果实黑心病，发病率变化范围为６０％～１００％。低于２１℃的采前低温影响是诱发菠萝黑心病的重要因子之一。在华南菠萝生产区，不同品种对黑心病敏感性的表现不同。因此，培育和栽培抗黑心病的菠萝新品种，将是一个控制黑心病腐烂的重要措施。The black heart of pineapple fruits induced by preharvest chilling tem-perature was studied and discussed．The incidence of blackheart induced by chilling tem-perature was 60％～100％in autumn and winter. The results suggested that the effect ofchilling temperature below 21℃ at preharvest was one of important factors in inducingof pineapple blackheart．In South China，there is a difference of sensibilitv to blackheartin different pineapple varieties. Therefore breeding and planting of new blackheart-resis-tant varieties of pineapple would be an important measure in control of blackheart ofpineapples.
