不同有机物对铁皮石斛试管苗生长发育的影响

研究不同有机物浸提液对铁皮石斛试管苗生长的影响。在相同的培养条件下，以8种含有不同有机物的培养基培养试管苗，60d后对试管苗的各种性状进行记录统计，并与对照（没加有机物提取液）进行比较分析。结果不同的有机物浸提液对试管苗的影响效果不一样。壮苗以加入白萝卜提取液、CH和CM为佳，生根以加入香蕉提取液为佳，要提高繁殖系数以不加有机物为佳。

Effects of Different Organic Matter on Regenerated Shoots of Dendrobium Candidum

To study the effects of water extract from different Organic Matter on growth of regenerated shoots from Dendrobium candidum Wall. ex Lindl. In the same culture condition, the regenerated shoots were cultured on MS medium with water extract of eight Organic Matter, the different growth status was scored and general analysed after 60d. Results There were different influence to the regenerated shoots that culture media with different water extract of Organic Matter. MS adding CH, CM or water extract of white radish was the better media for strengthening regenerated shoots, while MS with the water extract of banana was suitable for root growing, MS with nothing was the best media for propagation.
