摘要
本文叙述了外源赤霉素ＧＡ３、低温条件对采后菠萝果实黑心病发展的影响．说明外源赤霉素ＧＡ３和低温条件都是诱导菠萝黑心病的重要因子。菠萝黑心病是一种生理失调症。实验中，未发现化学杀菌剂对此种病症显现出防治效果，而采后贮前４０℃高温处理２４小时．则可以减少和延迟此病的发生，因此．后者是一种可以应用于商品菠萝果实黑心病防治的好方法。
This paper Stated the effect of exogenous gibberellic acid,GA3 and chilling temperature on the cause and development of post-harvest pineapple blackheart, and explains that the exogenous gibberellic acid, GA3 and chilling temperature are the important factors induced the blackheart.Post-harvest pineapple blackheart is a physiological disorder.Treatment at 40℃ for 24 hours before storage could reduce the incidence and delay the occurring of blackheart,but treatment with chemical fungicides were not effect in our experimeat.Therefore,the pretreatment is an useful method for controlling blackheart ofcommerciaL pineapple.
