摘要: 以福建铁皮石斛种子为材料,开展种子萌芽、壮苗生根适宜培养基配方试验研究,并对组培苗的移栽基质进行筛选。结果表明:以MS+蔗糖30g·L-1+琼脂7g·L-1为培养基,种子萌芽快,萌芽率高;1/4MS+蔗糖40g·L-1+马铃薯提取液100mg·L-1+琼脂7g·L-1是壮苗生根的最佳培养基;木屑:泥炭(1:2)的基质,组培苗移栽成活率、平均新芽数及大于3cm平均新芽数等3项指标最好。

Abstract: On an appropriate medium,Fujian's Dendrobium candidum Wall.ex Lindl was studied for its seed germination,plantlet strength,rooting and transplantation.The results indicated that the seeds germinated well and quickly on the medium consisting of MS +sucrose 30 g·L-1 +agar 7 g·L-1.To strengthen the plantlet and encourage root formation,the best formulation was found to be 1/4MS +sucrose 40g·L-1 +potato extract 100 mg·L-1+agar 7g·L-1.The transplanting survival rate,average number of new buds and average number of new buds that were longer than 3 cm could best be obtained when the mixture of sawdust and peat in the ratio of 1:2 was used for the plantlet transplantation.

Key words: Dendrobium candidum Wall.ex Lindl, tissue culture, medium
