The absorption spectra of Chl was different between flag leaf and hull, the absorbance of the medium that contain Chl of hull was more strong than that of flag leaf in zone of short wavelength when the Chl concentration of medium was the same.

• 谷壳与旗叶相同叶绿素浓度提取液的光吸收光谱特性不同，在短波区谷壳叶绿素提取液的光吸 收明显比旗叶叶绿素的高；
