研究中同时利用了3个不同的烟草品种，利用同样的方法和操作程序，但是最后根据烟草叶片中绿色荧光的检测结果发现，不同的烟草品种对OsWAK1：：GFP融合蛋白的表达差异很大。

At the same time, the intensity ratio of the ICT fluorescence to the LE fluorescence, I〓/I〓, shows a "bell"-shaped variation with increasing CTAB concentration The intensity ratio was found to level off after the CMC of CTAB Together with the data from UV-Vis absorption spectroscopy, electric conductance measurements and the control experiments with tetramethylammonium bromide, it was concluded that the"bell"-shaped variation in the intensity ratio before CMC is due to the formation of premicelle aggregates consisting of ICT fluorophore and CTAB.

此时，ICT荧光强度与LE荧光强度之比，I〓/I〓随CTAB浓度增大而呈&钟形&变化。当CTAB浓度高于CMC时，I〓/I〓为一常数。根据紫外-可见吸收光谱，电导以及四甲基溴化铵对照实验的结果可知，当CTAB浓度低于其CMC时，I〓/I〓的&钟形&变化是由于长链对二烷基氨基苯甲酸与CTAB组成的胶束前簇集体形成所致。
