摘　　要：以维加斯、柠檬冰糕、圣诞快乐等15个朱顶红品种的鳞茎为试材,进行不同品种鳞茎切割扦插繁殖特性的比较试验。结果表明,不同品种扦插繁殖能力差异显著。柠檬冰糕子球生成进程最快,插后25d子球开始生成,35d即进入子球生成盛期;诱惑鳞茎扦插成活率最高,为97.2%;双重惊喜种球繁殖系数最高,达38;综合考虑鳞茎扦插成活率与繁殖系数等因素,应选择抗性强和繁殖能力强的品种进行鳞片扦插繁殖更有利于朱顶红规模化种球的生产。The bulbs of 15 varieties of Hippeastrum hybridum, such as Vegas, Lemon Sorbet and Merry Christmas, were used as materials to compare the cuttage propagation characteristics among different varieties.The results showed that cutting propagation ability of different varieties was significantly different.The generation process of Lemon Sorbet was the fastest.The cormel begined at 25 d and turned into maturation period at 35 d after cutting.The survival rate of cottage bulbs was highest in Temptation which was 97.2%.The propagation coefficient was highest in Double Delight, that was up to 38.Based on the survival rate and propagation coefficient of bulb cuttings, the scale cutting propagation of the varieties with strong resistance and strong propagation ability were benefit to the production of the large scale germplasm of Hippeastrum hybridum.
