摘　　要：将假植成活率和成活植株的形态特征结合起来,作为评价指标,摸索分析了不同消毒处理、不同苗床基质、不同浓度NAA(萘乙酸)蘸根处理对甘蔗茎尖组培苗假植成活质量的影响。试验表明:两种不同消毒处理方式对甘蔗组培苗假植成活率的影响较小,但对成活植株质量的影响较大;不同苗床基质对甘蔗茎尖组培苗假植成活质量有一定影响;不同浓度NAA蘸根处理对甘蔗茎尖组培苗假植成活质量影响较大,成活植株的根长、株高、叶长、叶宽等性状,随着NAA浓度的变化,呈现出一定的规律性。29 foreign sugarcane varieties from national sugarcane germplasm nurse were test to evaluate their sucrose content and cane yield at the end of November, 2007 and January, 2008. The result showed that 14 sugarcane varieties from the total experimental varieties were excellent in yield and sucrose content. 2 sugarcane varieties from the 14 varieties possess strong ratoon, high yield and high sucrose, taking up 6.90%; and 6 belong to strong ratoon and high yield, about 20.69%; and 6 sugarcane varieties were only high sucrose, about 20.69%. These excellent varieties could be utilized as improving quality of sugarcane varieties.
