对甘薯近缘野生种 Ｉ． ｌｉｔｔｏｒａｌｉｓ Ｂｌｕｎｅ 愈伤组织植株再生进行研究。将叶片、叶柄外植 体培养在添加０ ．０２ ～０ ．０５ ｍ ｇ／ Ｌ２ ，４ － Ｄ 和０ ．５ ～２ ．０ ｍ ｇ／ Ｌ 激动素（ Ｋ Ｔ） 的 Ｍ Ｓ 培养基上，诱导愈伤组织。将形成的愈伤组织转移到 Ｍ Ｓ 基本培养基上３ ～４ 周后，观 察到植株再生。叶片、叶柄愈伤组织再生 植株频率分别达５５ ．５ ％ 和５０ ．０ ％ 。
Sweet potato relatives wild species I. The littoralis Blune callus plant regeneration was studied. Leaves and petiole explants were cultured at 0. 02 ~ 0. 05 m g / L2, 4 - D and 0. 5 ~ 2. 0 m g / L kinetin (K T) of M S medium, callus induction. Three to four weeks after the callus formation is transferred to M S minimal medium, plant regeneration is observed. Leaf, petiole callus regeneration plants frequency of 55 respectively. 5% and 50. 0%.
