蝴蝶兰快速繁殖关键技术研究

摘要

Picking tender leaves,shoot-tips,pedicel lateral bud,pedicel internode as explants to induce original corm,to search the best explants on tissue culturing of Phalaenopsis amabilis;Different culture medium with hormone combination were screened to original%以蝴蝶兰嫩叶、茎尖、花梗侧芽、花梗节间为外植体,进行原球茎诱导,探求蝴蝶兰组织培养的最适外植体;通过不同培养基及各种激素配比组合进行原球茎诱导、增值及试管苗生根试验,探索各阶段最优培养基配方。结果表明：茎尖和花梗腋芽是蝴蝶兰形成原球茎的较佳外植体;MS＋0.5 mg/L NAA＋1.0 mg/L 6-BA＋100ml/L椰乳是蝴蝶兰原球茎增殖的最佳培养基,增殖系数达8.98;1/2 MS培养基最利于侧芽萌发形成丛生芽;生根最适培养基为1/2MS＋1.0mg/LIBA＋0.5 mg/LNAA。
