太白米组织培养的研究

太白米地下鳞茎在MS附加不同浓度KT、BA、IAA、NAA、2，4－D的培养基上，可诱导产生愈伤组织，其中在MS附加NAA 0.5mg/L,KT0.1mg/L的培养基上愈伤组织诱导率最高，可达65％，且生长快；培养在MS附加2，4－D 1.0mg/L,KT 0.1mg/L培养基上的鳞茎可经不定根直接发育成新的鳞茎，由此建立了太白米的鳞茎再生体系，鳞茎再生率达2．17倍。

Study on the tissue culture of Notholirion bulbuliferum

The tissue culture and plant regeneration of notholirion bulbuliferum were studied in this paper and the result showed that;the calli could be induced from bulbule on the MS basicl mediums supplemented with different concentration of KT,BA,IAA,NAA and 2,4-D. The induction rate of calli were highest and reached to 65% on the medium of MS+NAA 0. 5 mg/L+KT 0. 1 mg/L. The bulbules which were cultured on MS + 2.4-D 1. 0 mg/L+KT 0. 1 mg/L medium could bring up new bulbules by adventitious root. The regeneration rate of bulbules was as high as 2. 17 times and the regeneration system were built.
