【摘要】 进行了霍山石斛种子在试管培养基上培育成苗的试验,结果表明:外源激素对霍山石斛种子萌发有抑制作用,因而种子萌发时不需添加激素。宜用Knudson加香蕉培养基,缺少香蕉时,可用1/2ER、1/2MS培养基。用自然光代替日光灯,用豆淀粉、糖、自来水或河水加营养元素配制培养基,可以降低生产成本1/2以上。更多还原

【Abstract】 The experiments on the Dendrobium tosaense plantlet formation in test tubefrom seed were carried out. The exogenous hormones inhibited the germinationof Dendrobium tosaense seeds. It was, therefore, unnecessary to add hormonesin the nutrient media during the period of germination. It was better to caltureon the Kundson with banana medium, but 1/2 ER and 1/2 MS media were alsosuitable when the banana was not available. For the calture of plantlets, fluor-escent lamps can be substituted with natural light, and media can be made ofcheap soybean statch,sugar and tap water or stream water in addition to nutrientelement to reduce the production costs by more than one half.更多还原
