摘要/Abstract

摘要： 对3 个红皮萝卜品种贮藏过程中肉质根不同部位木质素平均含量及糠心指数变化进行了研究。结果表明, 随着贮藏时间的延长, 糠心指数和不同部位木质素平均含量均增加; 木质素平均含量在贮藏后30 d 发生显著变化, 贮藏后50 d 达到极显著水平; 根皮部木质素含量变化较小, 且显著低于其它3 个部位; 糠心指数在贮藏后40 d 发生显著变化, 贮藏后50 d 达到极显著水平, 品种间不存在差异。通过回归分析得出, 根皮部木质素平均含量与糠心指数呈显著相关, 根头部、根中部和根下部木质素含量与糠心指数呈极显著相关。

Abstract: In this experiment, changes of average content of lignin in different parts of root and hollowing index in three varieties of red skin radish during storage were studied. The results showed as follows: hollowing index and average
content of lignin in different parts increase along with the extention of torage, average content of lignin increases significantly on 30th day after storage and increases at extremely significant level on 50th day after storage. The lignin content and its increase in skin part of root are less than these in other parts of root. Hollowing index increases significantly in 40
days of storage and at extremely significant level in 50 days of storage, but there is no difference between three varieties. Through the regression analysis, the change of average content of lignin in skin part is significantly correlative with that of hollowing index , but that in head, middle and down parts of root show an extremely correlation with hollowing index .
