摘要
以耐热性不同的3个甘蓝品种(夏光、西园4号、京丰1号)为材料,采用二次回归正交旋转组合设计(包括热激温度、热激时间2个因子)对种子进行热激处理,在苗期测定了热激处理对热害指数的影响。结果表明,热激处理对甘蓝幼苗热害指数有显著影响,幼苗热害指数表现为:京丰一号>西园四号>夏光;得出了最佳热激处理组合为42℃,2.3 h。
By the application of response surface design, the research on the effects of heat shock on three cabbage （ Brassica oleracea L. ） varieties （Xia Guang, Xi Yuan number 4, Jingfeng number 1） seeds was done for the selection of the different heat-resistant ability, The results showed that the heat shock treatment had a significant effect on the leaf heat injury index,the index sequence was Jingfeng No. 1 〉 Xi Yuan No. 4 〉 Xia Guang; and the best heat shock condition was 42.30℃ for 2.26 hours.
