采用不同浓度的植物生长调节剂B_9对试管苗进行壮苗研究,并观察壮苗后生产微型薯的产量.结果表明:20～40 mg · L~(-1)B_9对脱毒马铃薯试管苗兼有促进增殖和复壮的双重效果,而且其试管苗移栽成活率和生根率均为100%,其中尤以40 mg · L~(-1) B_9效果最佳,生长旺盛,结微型薯数量和重量达到最大值.
採用不同濃度的植物生長調節劑B_9對試管苗進行壯苗研究,併觀察壯苗後生產微型藷的產量.結果錶明:20～40 mg · L~(-1)B_9對脫毒馬鈴藷試管苗兼有促進增殖和複壯的雙重效果,而且其試管苗移栽成活率和生根率均為100%,其中尤以40 mg · L~(-1) B_9效果最佳,生長旺盛,結微型藷數量和重量達到最大值.

In vitro seedlings were treated with different concentrations of plant growth regulator B_9 in this study for observations of tuberization after the treatment.The result showed that 20～40 mg · L~(-1)B_9 have dual effects of promoting multiplication and rejuvenation of virus-free potato plantlets.The survival and rooting rates of transplanted vitro seedlings treated with 20～40 mg · L~(-1)B_9 were 100%,the most vigorous growth showed at 40 mg · L~(-1)B_9 with the maximum number and weight of tubers.
