摘要: 以金线莲试管苗为材料,MS+6-BA 3.0 mg/L+NAA 0.3 mg/L+琼脂7 g/L+蔗糖25 g/L为基础培养基,采用SPSS正交设计试验,研究不同添加物、不同瓶子规格、不同光质等对金线莲试管苗生长过程中多糖含量积累的影响。结果表明,影响金线莲多糖含量的顺序为光质>添加物>瓶子规格。添加物中香蕉泥的均值最大为0.291,并且香蕉泥与苹果汁和胡萝卜汁之间具有显著性差异(P<0.05)。光质中蓝光的均值最大为0.289,并且蓝光与白光和红光之间具有显著性差异(P<0.05)。瓶子规格中6.5 cm的均值最大为0.279,与8.0 cm瓶子对比有显著性差异(P<0.05),与9.0 cm瓶子对比没有显著性差异(P>0.05)。优化后金线莲多糖含量累积的培养条件为MS+6-BA 3.0 mg/L+NAA 0.3 mg/L+琼脂7 g/L+蔗糖25 g/L+香蕉泥(pH 5.8)50 g/L+6.5 cm培养瓶+蓝光。

Abstract: The in vitro plantlets were used as the materials,and MS+3.0 mg/L 6-BA+0.3 mg/L NAA+7 g/L agar+25 g/L glucose was used as the basal medium for studying the effects of organic additives, bottle sizes and light qualities on the accumulation of polysaccharide content during the growth of in vitro plantlets by the L9(34) orthogonal experimental design during in Anoectochilus roxburghii. The results showed that the order of polysaccharide content was light quality>additive>bottle size. The average value of banana mud in the additive was 0.291,and there was a significant difference between banana mud and apple juice and carrot juice(P<0.05). The mean value of blue light in the light mass is 0.289, and there is a significant difference between blue light and white and red light (P<0.05). The mean value of 6.5 cm in the bottle size was 0.279,which was significantly different from that of the 8.0 cm bottle(P<0.05),and there was no significant difference(P>0.05). Consolidated results showed that the best culture conditions for the accumulation of polysaccharide content was MS+6-BA 3.0 mg/L+NAA 0.3 mg/L+7 g/L agar+25 g/L glucose+50 g/L banana(pH 5.8) in the culture bottle with 6.5 cm diameter in the blue light.
