43份品种(系)及2份野生种材料的试管单节苗于3种温度条件下,在21个月的培养期中业已形成微型串薯,此期间在10℃条件下,即不再作培养基的添加仍能继续形成微型著,平均每节腋芽结薯3.3个,这种技术对马铃薯种质资源的长期保存将十分有用。
43 single-seedlings of two varieties (lines) and two wild-type cucumbers were grown in mini-series at 21 ℃ for three months under the condition of 10 ℃ The addition of base can continue to be micro-sized with an average of 3.3 tubers per axillary bud. This technique will be very useful for the long-term preservation of potato germplasm.
