摘要
为探讨马铃薯原原种生产适宜的脱毒苗类型问题,选用‘荷兰15号’,‘尤金’和‘克新13号’三个品种的脱毒苗为试验材料,采用单因素随机设计,设计正常试管苗(对照),6叶龄期去掉带3个叶片茎尖的试管苗,6叶龄期获得的带3个叶片茎尖的扦插苗,9叶龄期获得的带3个叶片茎尖的扦插苗共4种脱毒苗类型。利用方差分析探讨了不同脱毒苗类型对马铃薯原原种的产量性状(商品薯产量和总产量)和经济参数(利润和经济效益)的影响。研究结果表明:正常试管苗(对照)和6叶龄期获得的带3个叶片茎尖的扦插苗处理的商品薯产量最高,正常试管苗(对照)和6叶龄期去掉带3个叶片茎尖的试管苗处理的总产、利润和经济效益均较高。
Plantlets in vitro of the varieties, ‘Hol and 15’ , ‘Youjin’ , and ‘Kexin 13’ were used as experimental materials in order to understand the effects of source material on minituber production. Four treatments, transplantation of whole plantlets in vitro （control）, leftover of transplants after removal of apical stem with three leaves at six leaf age, cutting of apical stem with three leaves at six leaf age, and cutting of apical stem with three leaves at nine leaf age, were tested in a completely randomized design, and analyzed using analysis of variance for their influences on yield characters （marketable minituber yield and total minituber yield） and economic parameters （profit and economic benefit）. Transplantation of whole plantlets in vitro （control） and cutting of apical stem with three leaves at six leaf age gave the best marketable minituber yield, while transplantation of whole plantlets in vitro （control） and leftover of transplants after removal of apical stem with three leaves at six leaf age had the highest total yield, profit and economic benefit.
