With the cultiva of Red lion and Orange Souvereign of amaryllis(Hippeastrum hibridum)as test material,their bulb scales were used as explants in tissue culture to study the influence of 6BA and NAA in different concentrations on their regeneration.

• 以朱顶红品种为试材,在组织培养过程中,以鳞茎为外植体,研究6BA和NAA的不同浓度对其直接诱导再生植株的影响。
