中文摘要: |
以青薯9号马铃薯为试材,研究不同贮藏温度(4、10、15、20 ℃)对150 d贮藏期间马铃薯块茎品质及采后生理的影响。结果表明,贮藏过程中,马铃薯块茎淀粉含量随贮藏时间的延长呈下降趋势,还原糖含量、发芽率、失重率、腐烂率以及相对电导率、丙二醛(MDA)含量呈上升趋势,过氧化物酶(POD)和多酚氧化酶(PPO)活性呈先上升后下降的趋势。贮藏温度不同对马铃薯贮藏期间的品质及生理的影响不同,20 ℃下马铃薯块茎的贮藏品质及生理劣变最快,其次是15 ℃和10 ℃,4 ℃条件下贮藏能够较好地保持马铃薯块茎的商品价值和食用价值。 |
英文摘要: |
Qingshu 9 potato tubers were used as raw materials to investigate the impact of different storage temperature(4, 10, 15 and 20 ℃) on quality and postharvest physiology of potato tubers during storage of 150 days. The result showed that,during the storage, starch content declined, while reducing sugar content, weight loss, sprout rate, decay rate, conductivity and MDA content increased, the activity of POD and PPO showed a trend of rise first and then fall. Different storage temperature have different effects on potato storage quality and postharvest physiology. The fastest changes of quality and postharvest physiology were observed from potato stored at 20 ℃, and followed by 15 ℃ and 10 ℃,4 ℃ was the most suitable temperature for storing potato tuber, it is helpful to maintain storage quality and delay senescence of potato tubers. |
