摘要
试验采用正交实验设计法,研究了不同浓度的α-萘乙酸(NAA)、比久(B)9)、6-苄氨基腺嘌呤(6-BA)和大量元素组合对马铃薯品种费乌瑞它脱毒试管苗壮苗培养的影响,以期为费乌瑞它脱毒试管苗壮苗培养优化培养体系的建立提供理论参考。结果表明:在4个因素中对茎粗、根数、根长和单株干重影响大小依次为:大量元素>B9>NAA>6-BA;而对苗高、有效茎节数、活叶数和单株鲜重影响最大的为大量元素,影响最小的为NAA。新复极差法显著性测定结果显示,除4个处理外,其余处理与对照间有效茎节数、活叶数、茎粗、根长、根数、单株鲜重和干重差异均达到极显著水平。MS(100 mL/L大量元素)+0.03 mg/L NAA+10 mg/L B9+2%白糖+0.6%琼脂培养基除根长外各性状的值均最大,表明它是适合‘费乌瑞它’脱毒试管苗壮苗培养的最佳培养基。
Effects of the various combinations of NAA, B9, 6-BA and macro-element on the potato planUets in vitro of cv. Favorita were studied by using the orthogonal experiment design in this research, which would provide a theoretical reference for the establishment of optimized culture system for strengthening plantlets in vitro. Effect order of the factors on stem diameter, root number, root length and plant dry weight was macro-element 〉B9 〉NAA 〉6-BA. For plantlet height, node number, leaf number and fresh weight, macro-element was most influencing, while NAA least influencing. For node number, leaf number, stem diameter, root length, root number, and fresh and dry weight per plantlet in vitro, all treatments but four were highly significantly different from the control. The medium, MS ＋ NAA 0.03 mg/L ＋ B910 mg/L ＋ white sugar 2% ＋ agar 0.6%, except root length, gave the highest value, suggesting that this medium is most suitable for＇Favorita＇ to produce robust plantlets in vitro.
