Prepared with this combination, the enzymic protein expression, enzyme activity and activity ration are significantly higher than other treatments of concentration and time.

此技术组合生产的酶蛋白的表达量、酶活性和比活性，均显著高于其他浓度和时间的处理。

It has been reported that ARF gene expression was not effected by auxin concentration.

已有报道说ARF基因的表达都不受生长素浓度的影响。

The expression of poplar disease resistance in callus tissues is greatly affected by concentration of auxins and cytokinins in the medium, inoculum density and temperature.

来自抗病无性系的愈伤组织也表现抗病。 愈伤组织抗病性表达受培养基的激素浓度及比例、病原菌的接种量和接种温度影响较大；
