摘　　要：以8种园林植物‘大同’黄花菜、‘金娃娃’萱草、‘古铜红’鸢尾、‘崂峪’苔草、‘青绿’苔草、金银花、顶花板凳果和山麦冬为试材,在自然降温条件下,采用测定冷害指数及光合作用相关参数的方法,研究了低温对8种园林植物的耐寒性,以期为园林绿化提供优良耐寒品种。结果表明:顶花板凳果为8种植物中耐寒性较强的植物。通过冷害指数的测定,‘大同’黄花菜冷害指数上升最快,而山麦冬和顶花板凳果变化较缓,表明‘大同’黄花菜耐寒性最弱,山麦冬和顶花板凳果的耐寒性较强;对8种园林植物所测指标进行隶属函数分析,得出8种植物的耐寒性从大到小依次为顶花板凳果>山麦冬>金银花>‘崂峪’苔草>‘青绿’苔草>‘古铜红’鸢尾>‘金娃娃’萱草>‘大同’黄花菜。The experiment selected Hemerocallis lilioasphodelus Linn, Hemerocallis fulva,Iris tectorum Maxim, Carex spp.,Lonicera japonica,Pachysandra terminalis Sieb.et Zucc, Liriope spicata(Thunb.) Lour.as the test materials, the cold damage index and photosynthetic parameters were measured under natural cooling condition, the cold tolerance of eight ornamental plants was studied, in order to provide excellent cold-resistant varieties for landscaping.The results showed that the cold damage index of Hemerocallis lilioasphodelus Linn increased the most rapidly, while the change of Pachysandra terminalis Sieb.et Zucc and Liriope spicata(Thunb.) Lour.was slow, indicating that the cold tolerance of Hemerocallis lilioasphodelus Linn was the weakest, the cold tolerance of Pachysandra terminalis Sieb.et Zucc and Liriope spicata(Thunb.) Lour.was strong.Based on the analysis of the subordinate function of the indexes measured by eight ornamental plants, it concluded that the cold tolerance of eight plants as follows from large to small was Pachysandra terminalis Sieb.et Zucc>Liriope spicata(Thunb.) Lour.>Lonicera japonica>‘Laoyu’ Carex>‘Qinglyu’ Carex>‘Gutonghong’ Iris tectorum Maxim>‘Jinwawa’ Hemerocallis fulva>‘Datong’ Hemerocallis lilioasphodelus Linn.
