抗机械伤害褐变马铃薯品种(系)的筛选*
首发时间:2010-06-18
摘要:采用分光光度法研究了21个马铃薯新品种在机械伤条件下的褐变。4℃褐变24h后,品种S03-259、YS301、S04-801、JS05-53-275和S04-5156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5个品种(系)可作为抗机械伤害褐变品种(系)加以研究和开发利用。

In vitro screening of potato (Solallum tuberosum L.) cultivars (Lines)for browning tolerance responding to mechanical stress
Abstract:In vitro screening of 21 potato cultivars for browning tolerance responding to mechanical stress was investigated by spectrophotometric method. It was found that browning degree of five potato varieties (YS301, S03-259,S04-801,JS05-53-275 and S04-5156) were between 0.114 ~ 0.288 at 4 ℃ for 24h, and their browning degree at 30℃ for 20min is very small, so the five potato varieties can be used as browning tolerance candidates for research and utilization.
Keywords: Potato (Solanum tuberosum L) browning Cultivars mechanical stress
