【摘要】 以9个辣椒新品种为试材,分别测定辣椒生长指标和耐低温生理指标,采用隶属函数法进行分析评价,评价9个辣椒品种越冬生产耐低温性,以期为越冬栽培提供参考。结果表明:9个辣椒品种可以划分为3个不同耐低温等级组群,即耐低温性强组群("1105"、"1101"和"1104"),耐低温性中等组群("1103"、"亮剑"和"绿剑65")和耐低温性弱组群("红罗丹"、"奥黛丽"和"1102");在冬季温室内平均气温低于10℃条件下,"1105"在9个辣椒品种中耐低温性最强,在生长指标和耐低温生理指标方面表现要优于其它品种,隶属函数平均值为0.826,为9个辣椒品种最高的。综合来看,"1105"具有较强的耐低温性,在保护地越冬栽培中具有推广价值。更多还原

【Abstract】 9new pepper varieties were used as materials,the growth index and physiological index of tolerance of low-temperature of 9pepper varieties were evaluated with the methods of membership function.The tolerance of low-temperature of 9peppers were studied and evaluated to offer reference for wintering cultivation in greenhouse.The results showed that the9 pepper varieties were divided into 3species groups with different tolerance of low-temperature.The first species group showed strong tolerance of low-temperature which included‘1105’,‘1101’and‘1104’.The tolerance of low-temperature of second species group were moderate which included‘1103’,‘Liangjian’and ‘Lyujian 65’.Tolerance of lowtemperature of the third species group were the weakest which included‘Red Rodin’,‘Audrey’and‘1102’.The‘1105’showed the strongest ability of tolerance of low-temperature,which grown winter greenhouse where mean temperature was below 10℃.The plant growth index and tolerance of low-temperature physiological indexes were better than other varieties.Membership function mean was 0.826.In general,‘1105’showed a strong tolerance of low-temperature,had extended value for cultivation over wintering in greenhouse.更多还原
