2,4-D和6-BA对提高钝顶螺旋藻(Spirulina platensis Geitler)生物产量的效应

The Effect of 2,4-D and 6-BA on the Biological yield of Spirulina platensis Geitler

２．４－Ｄ和６－ＢＡ对于钝顶螺旋藻藻株Ｄ和藻株Ｅ的生物产量具有明显的提高趋势。其最适浓度为：６－ＢＡ１０ｍｇ／Ｌ，２．４－Ｄ０．１ｍｇ／Ｌ（对藻株Ｄ）和１ｍｇ／Ｌ（对藻株Ｅ）。藻株Ｆ的生物产量基本上不受２．４－Ｄ和６－ＢＡ的影响。

Studies on the three varieties (D, E and F) of Spirulina platensis Geitler showed that 2,4-D and 6-BA could effectively promote the biological yields of variety D and E, but were ineffective to variety F. The optimal concentrations of 2,4-D to variety D and E were 0.1 mg /L and 1 mg /L respectively, and 10 mg /L was the optimal concentration of 6-BA to both varieties D and E.
