- 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。
- Abstract:
- 9 new pepper varieties were used as materials，the growth index and physiological index of tolerance of low-temperature of 9 pepper varieties were evaluated with the methods of membership function.The tolerance of low-temperature of 9 peppers were studied and evaluated to offer reference for wintering cultivation in greenhouse.The results showed that the 9 pepper varieties were divided into 3 species 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 low-temperature 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.
