| 摘 要： | 半夏采用块茎、叶片、叶柄为外植体进行组织培养均可诱导成苗.块茎在培养基1.0mg/L 6-BA+0.1mg/L NAA中诱导率高为96.7%,在培养基2.0mg/L 6-BA+0.1mg/L NAA中增殖倍数高为8.5倍.叶片、叶柄在培养基3.0mg/L 6-BA+0.5mg/L NAA中小块茎的诱导率较高达86.7%,在培养基2.0mg/L 6-BA+0.1mg/L NAA中增殖倍数较高为5.4倍.半夏试管苗在增殖培养中同时分化出根,可免去诱根环节.

| Abstract: | Pinellia tenata(Thunb.) Breit will be induced to seedlings by tissue culture with the tuber,blade and leafstalk.The induced rate will be 96.7 percent if the tuber is put in the culture medium of 1.0mg/L6-BA+0.1mg/LNAA.The rate of increase will be 8.5 times in the culture medium of 2.0 mg/L6-BA+0.1mg/LNAA.The induced rate will be 86.7 percent if the blade and are leafstalk are put in the culture medium of 3.0mg/L6-BA+0.5mg/LNAA.The rate of increase will be 5.4 times in the culture medium of 2.0mg/L6-BA+0.1mg... |
