| 中文摘要: |
| ：冷藏能有效延长菠萝保鲜时间，但菠萝在低温下贮藏容易发生黑心病，品质变劣，严重制约了菠萝
产业发展。为探讨热处理减轻低温贮藏下菠萝黑心病的作用，以菠萝主栽品种巴厘菠萝为试材，用热空气处理采
后菠萝，研究热处理对贮藏期菠萝生理生化指标的影响，结果表明：热处理显著减轻了采后菠萝黑心病指数，降
低了采后菠萝MDA 含量，提高了冷藏期菠萝H2O2 含量，延缓了整个贮藏期菠萝的SOD、POD 活性下降速率，同
时提高了冷藏期CAT 活性，POD 活性与黑心病指数显著相关。说明热处理可提高氧化酶活性，延缓采后菠萝果实
衰老，从而减轻菠萝黑心病。 |
| 英文摘要: |
| Cold storage is effective to prolong the storage life of pineapple fruit，but a major problem is that low
temperature usually causes blackheart in fruit，adversely affecting the quality and nutritional value of fruit，which
seriously affects the pineapple industry development. To investigate the mechanism of hot treatment on alleviating
pineapple blackheart，using cultivar‘ Paris’ as material and hot air as treatment method，the effects of hot treatment
on physiological and bio-chemical changes of harvested pineapple were studied，results showed that the hot treatment
could effectively alleviate the blackheart index of harvested pineapple. The MDA contents of harvested pineapple were
decreased by hot treatment，and the H2O2 contents increased. The hot treatment delayed the descending rate of SOD and
POD activities during the whole harvested period，meanwhile the CAT activity increased. The POD activity was correlated
significantly with blackheart index. These results suggested that hot treatment could increase the antioxidase activities to
delay the pineapple senescence，thus reduced the blackheart of pineapple. |
