珍珠番茄快速繁殖技术

以珍珠番茄幼叶、带腋芽茎段为材料进行组织培养，对其快速繁殖技术进行研究．结果表明：1)以带腋芽茎段为外植体，在MS BA2mg/L NAA0．1mg/L培养基上诱导的不定芽数多，是1条较佳的快速繁殖途径；2)以幼叶为外植体，在MS BA2mg/L IAA0．5mg/L培养基上诱导的愈伤组织质量好，但分化成苗能力一般．分化培养基以MS BA2mg/L较好；3)生根培养基以MS IAA0．2mg/L和MS NAA0．1mg/L IAA0．1mg／L生根率高且根粗壮．

Studies on Rapid Propagation of Peral Tomato

The paper reports the plant regeneration and rapid propagation about the young leaves and steams with buds of peral tomato,which shows: 1) There are large number of adventive buds from steams with buds on the MS medium with BA 2 mg/L and NAA 0.1 mg/L;2)The quality of callus inducted from the leaf explants cultured on the MS medium with BA 2 mg/L and IAA 0.5 mg/L is the best.However the callus have the ordinary differentiation potential. It's suitable to differentiate buds on the MS medium with BA 2 mg/L;3) The MS mediums with IAA 0.2 mg/L or with NAA 0.1 mg/L and IAA 0.1 mg/L is with high rooting rate and thicky and strong roots.
