| 摘 要： | 采用分光光度法研究了21个马铃薯新品种(系)在机械损伤条件下的褐变。筛选试验表明,4℃褐变24 h后,品种(系)云薯301、S03-259、S04-801和JS05-53-275的褐变度变化值为0.004~0.081,而且初始褐变度都很小,因此这4个品种(系)可作为抗机械损伤褐变品种(系)加以研究和开发利用。 |
| 关 键 词： | 马铃薯 褐变 品种 机械损伤 |

| Abstract: | Screening of 21 poato cultivars(lines) for browning tolerance responding to mechanical stress was investigated by the spectrophotometric method.It was found that the variation of browning degree among four potato lines(Yunshu 301,S03-259,S04-801 and JS05-53-275) were between 0.004 and 0.081 at 4℃ for 24h,and their initial browning degree was very small,so the four potato lines could be used as browning tolerance candidates for research and utilization. |
| Keywords: | potato(Solanum tuberosum L) browning cultivar mechanical stress |
