    摘要:

    以北京地区11个芹菜品种为试验材料,测定其在贮藏过程中含水量、叶绿素含量、呼吸强度、相对电导率、纤维素含量和木质素含量的变化,并对其感观品质进行评价。结果表明:贮藏期内,日本小香芹和白芹的水分含量下降最快;马家沟、帝王、玉皇芹菜的叶绿素含量均保持在较高水平,而紫芹和白芹较低,但玉皇和白芹下降程度最大;白芹在贮藏第1天出现呼吸峰值开始进入衰老阶段;贮藏期内白芹和紫芹的相对电导率上升幅度较大;白芹在贮藏第4天时失去商品性;白芹木质素含量增加幅度最大,而斯地德木质素含量增加最少。综合各项指标分析,北京地区主要芹菜中贮藏性较好的品种为斯地德,贮藏性较差的品种为白芹。

    Abstract:

    Eleven kinds of celery in Beijing were used. Six Indices including water content, chlorophyll content, respiration intensity, relative conductivity, cellulose content and lignin content of celery were measured. The results showed that, during the storage period, water content in Japanese Small Parsley and White Celery decreased sharply; chlorophyll content in Majiagou, Emperor and Jade Emperor maintained at a high level, but it is low in Purple Celery and White Celery, while the lowest level appeared in Jade Emperor and White Celery; White Celery entered the stage of senescence in the 1st day with the respiratory top; White Celery and Purple Celery's relative conductivity increased much more than the others; White Celery lost its commodity in the 4th day; lignin content of White Celery is highest in all cultivars, while Sidide showed the lowest. According to this study, Sidide owned a best storage characteristic, but White celery was the worst one.
