唐山地区引种宿根花卉的抗寒性研究
Study on Cold Resistance of Introduced Ratoon Flowers in Tangshan Area
摘要
Abstract
[Objective]The study was aimed to understand the cold resistance of 7 perennial ratoon flower plants. [Method]7 perennial root flower plants in Tangshan were chose as material, the paper researched the changes of leaf morphology at different low temperature stresses, SOD activity, soluble protein content, cell membrane permeability. [Result] Percentage of electrolyte leakage of 7 kinds of ratoon flower had been changed sharply in low temperature stress and control group. Membrane permeability increased gradually with the depth of stress degree and continuous stretching of stress time, but the ranges are different from each variety. According to variation of SOD and soluble protein content, the paper explained the different cold resistance at the physiological biochemical mechanism of cold resistance aspect. The results showed that the changes of SOD and soluble protein content were consistent with growth restoration observation.[Conclusion] Based on the results of morphology and physiological biochemistry deter mination, cold resistance of 7 kinds of ratoon flowers from high to low in turn were, Dianthus plumarius, Sedum kamtschaticum Fisch, Veronica spicata'Romiley Purple', Sedum spectable 'Brilliant', Monarda 'Croftway', Rudbeckia nitida 'Herbstsonne', Hemerocallis fuava.关键词
