摘　　要：为了研究高二氧化碳处理对马铃薯绿变和龙葵素含量的影响,研究了光照贮藏期间,不同时间高二氧化碳处理后马铃薯表皮a值、叶绿素和龙葵素含量的变化。结果表明,随着贮藏时间的延长马铃薯表皮a值下降,颜色趋于绿色,高二氧化碳处理能够抑制马铃薯表皮a值的降低,贮藏期间HCO2-24处理表皮a值最高;叶绿素含量均有所升高,贮藏到12天,对照叶绿素含量达到17.11mg/kg,HCO2-12处理含量为7.10mg/kg,HCO2-48处理含量为4.80mg/kg,而HCO2-24处理含量为3.45mg/kg,从试验数据可以看出,高二氧化碳处理能够控制马铃薯绿变,延长货架期;贮藏后龙葵素含量升高,而HCO2-24处理含量有所降低,但差异不显著。In order to study the effect of high carbon dioxide treatment on greening and solanine content of potatoes,stored under light condition,changes in a value,chlorophyll and solanine content of potato peel with different time of high carbon dioxide treatment were investigated.Results showed that a value of potatoes decreased with extension of the storage time,the color tended to green.High carbon dioxide treatment could inhibit the decrease of a value of the potato peel,a value of HCO 2-24 treatment maintained maximum during storage.Chlorophyll content of all treatments increased,until 12 days of storage,the content of control treatment was at 17.11mg/kg,HCO 2-12 at 7.10 mg/kg,HCO 2-48 at 4.80 mg/kg,whereas HCO 2-24 at 3.45 mg/kg.Based on the experimental results,high carbon dioxide treatments could inhibit potato greening and prolong its shelf life.Solanine content increased after storage;however,the content of HCO 2-24 treatment was not decreased obviously.
