摘　　要：目的:研究N.‘Avalanche’等9个荷兰水仙品种在合肥地区的引种种植及繁育试验。方法:以引进的9个荷兰水仙品种为试验材料,在合肥地区露地种植,对其植物学特征、观赏特性、物候期和种球繁殖等进行观测。结果:9个荷兰水仙品种均能正常出苗、生长、开花和繁殖,但不能结实;不同品种花期差异较大,自2月中旬至4月中旬,早花品种N.‘Golden Soleil d′Or’与晚花品种N.‘Recurvus’初花期相差46 d;除N.‘Recurvus’外,其他品种为伞形花序;2年生物学性状比较,多数品种的株高、花葶高和叶长显著增加,而花部性状表现出不同程度减小。种球繁殖系数在1.02~3.88,种球产量增长率为136.26%~191.84%。结论:9个荷兰水仙品种在合肥露地栽培均能正常生长并且开花,其生活史,且株型、花型、花色各具特色。Objective:To study the introduction,cultivation and bulb propagation of nine Narcissus varieties including N.‘Avalanche’in Hefei.Methods:Nine introduced Narcissus varieties were planted in the open field in Hefei,and their botanical characters,ornamental characteristics,phenological period and bulb propagation were observed.Results:All the nine Narcissus varieties could sprout,grow,blossom and reproduce normally,but could not bear fruit.The flowering period from the middle of February to the middle of April,there was a difference of 46 day between the early-flowering variety N.‘Golden Soleil d'Or’and the late-flowering variety N.‘Recurvus’.Except for N.‘Recurvus’,the other varieties were umbels.The plant height,scape height and leaf length of most varieties have increased significantly in the second year of planting,while the characteristics of flower traits decreased in varying degrees.The coefficient of bulb propagation is 1.02-3.88,and the growth percentage of bulb yield was 136.26%-191.84%.Conclusion:all the nine Narcissus varieties can grow and bloom normally in the open field in Hefei,and their plant type,flower type and flower color have their own characteristics.
