低温胁迫下不同月季品种的抗寒性评价
Evaluation of Cold Resistance in Different Chinese Rose Varieties under Low Temperature Stress
摘要
Abstract
To provide a scientific basis for selecting Chinese rose varieties for winter cultivation in double-layered greenhouses in Lanzhou New Area,this study subjected 5 Chinese rose varieties to low temperature stress and analyzed changes in their growth and physiological and biochemical indicators to identify those with strong cold resistance.Results showed that the varieties Fenshan(grafted with Muxiang)and Feishan experienced the least reduction in fresh weight under stress,with Fenshan showing the most significant decrease.Fenshan(grafted with Muxiang)and Zhumoshuanghui showed the least reduction in dry weight.Fenshan(grafted with Muxiang)and Fenshan had lower relative electrical conductivity and malondialdehyde content,indicating less lipid peroxidation.Compared to other varieties,Fenheping had the highest content of free proline.Fenshan(grafted with Muxiang)and Fenheping had higher contents of soluble sugars and proteins than other varieties.Principal component analysis indicated that the strongest cold-resistant varieties were Fenheping and Feishan,followed by Fenshan(grafted with Muxiang),with Fenshan and Zhumoshuanghui being less cold-resistant.Based on these results,it is recommended to prioritize the varieties Fenheping and Feishan for winter cultivation in double-layered greenhouses in the Lanzhou New Area.关键词
