摘要
以引进的20个洋水仙品种为试验材料,进行露地栽培试验,对其物候期、观赏特性和种球繁殖性状进行观测,并采用层次分析法(AHP)开展引种适应性评价。结果表明:根据花期,20个洋水仙品种可分为两组,其中Narcissus‘Ziva’单独属于秋季开花组,在10月下旬萌芽,花期11-12月,翌年5月下旬枯叶,其余19个品种属春季开花组,1-2月萌芽,花期3-4月,5-6月枯叶,物候期有一定的差异性;根据观赏性状调查结果,依据英国皇家园艺学会分类法,可将20个品种分为9类;多数品种种球繁殖情况较差,其中Narcissus‘Julia Jane’、Narcissus‘Hawear’、Narcissus‘Ziva’和Narcissus‘Martinette’的繁殖系数较高;根据AHP评价结果,引种的20个洋水仙品种可划分为3个等级,其中Ⅰ级品种有8个,综合表现较好,建议在舟山引种推广,Ⅱ级品种有6个,Ⅲ级品种有6个,表现一般或较差。
Twenty introduced Narcissus cultivars used as experimental materials were cultivated under open-field conditions in Zhoushan City,observing their phenological period,ornamental characteristics and bulb propagation,whose results were applied to carry out the adaptability evaluation of the introduced cultivars by using the Analytic Hierarchy Process(AHP).It is found that according to the flowering period,the 20 cultivars could be divided into two groups,in which Narcissus‘Ziva’is the sole cultivar flowering from November to December in the autumn,germinating in the late October,withering in late May of the following year.The spring flowering group including the remaining 19 cultivars,germinate from January to February,flower from March to April,wither from May to June,with certain variability in their phenological periods.In the light of survey of ornamental traits,the 20 cultivars can be divided into 9 categories basing on the Royal Horticultural Society’s classification;most cultivars had poor bulb propagation,Narcissus‘Julia Jane’,Narcissus‘Hawear’,Narcissus‘Ziva’and Narcissus‘Martinette’showed higher reproduction coefficients;according to the results of AHP evaluation,the introduced Narcissus cultivars were assigned to three classes,eight of which belonged to Class I species with better overall performance,six Class II species,six Class III species.Eight Narcissus cultivars in the above discussion are recommended to be introduced and promoted in Zhoushan City.
