马铃薯脱毒苗在不同时期移栽对生产原原种产量的影响

Effects of Transplanting Times of Potato Plantlets in vitro on Minituber Yield

为探讨马铃薯脱毒苗生产原原种的适宜移栽时期问题,选用主栽品种‘荷兰15号’和‘克新13号’的脱毒苗为试验材料,采用单因素随机设计,设3月1日、3月15日、3月29日、4月12日和4月26日共5个移栽时期,研究不同移栽时期对马铃薯原原种商品薯产量和总产的影响。结果表明:无论是‘荷兰15号’还是‘克新13号’的脱毒苗,如果在3月1日移栽,可以获得较高的原原种总产量和商品薯产量。

The plantlets in vitro of the varieties ＇Netherland 15＇ and ＇Kexin 13＇ were selected as experimental materials,and a single factor randomized complete block design was applied to investigate adequate transplanting time for minituber production.March 1st,15 th,29 th,April 12 th,and 26 th were set as transplanting times to study the effects of different transplanting times on marketable minituber yield and total minituber yield.The results indicated that high yields of both marketable minituber and total minituber were obtained when transplanting was done on March 1 st for these two varieties.
