| 摘 要： | 对马铃薯试管苗液体培养过程中所需的温度、光照、营养液浓度等条件进行了研究。结果表明:马铃薯试管苗适应用清水生根,在无机盐离子浓度0.05%～1.25%营养液中生长。在昼夜温度变幅为20～35℃的智能温室中,采用自然光照,脱毒马铃薯试管苗3d开始生长,5d根生齐,在适合的营养液培养条件下,7d达到根长4.5～5.0cm,根数15～22根,茎长6.0～8.0cm,茎粗1.4～2.2cm,叶片数7片,一株可剪顶,切段扦插2～3株,母苗可在侧芽生长后移栽结薯。该法繁殖速度快,成本低,省人力,对技术人员要求不高,是脱毒马铃薯试管苗繁殖的最为有效的途径。

| Abstract: | The temperature,illumination intensity and nutrition liquid concentration for the nutrition liquid culture technology of virus-free potato tube plants were researched. The results showed that the potato tube plants rooted well in pure water and plants were more vigorous in 0.5%～1.25% inorganic-salt concentration. In the 20～39 centigrade intellectualized greenhouse and sunlight irradiation condition,the virus-free potato tube plants began to take roots within 3 days,and rooting well needed 5 days. In the suitable conditions,a plant with 15～22 roots 4.5～5.0 cm in length,a stem 6.0～8.0 cm in length and 1.4～2.2cm in diameter,and 7 leaves was reached within 7 days. The plant could reproduce 2～3 individual plants by cutting and the mother plants could be planted and produced small virus free potatoes. This nutrition liquid culture technology is one of the most effective method for rapid propagation of virus-free potato tube plants because of its high propagation coefficient,cheap cost,and easy learned techniques . |
