Abstract:

When paraffin sections of young roots were observed by a common optical microscope, the obtained images were lack of three-dimensional effect. The paper gave a method to obtain a three-dimensional-effect image of the endodermis and Casparian strip in Lens culinaris. Using paraffin section technique and a common optical microscope, the digital photos of the endodermis and Casparian strip in L. culinaris were taken, and then the three-dimensional-effect anatomical images were obtained from the two-dimensional images through optical information analysis with word software. After optical information of two-dimensional images of the endodermis and Casparian strip in L. culinaris was analyzed, the three-dimensional-effect images were obtained. These images were similar to SEM micrographs. In the images the structures of the endodermis and Casparian strip were very clear, and the so-called Casparian strip was not the true structure, which was formed by the dehydrated protoplasts of the endodermis in the process of paraffin sections. The imaging light and its digital photos of a common optical microscope contained a large amount of optical information about three-dimensional structures and chemical compositions etc. of the imaging objects, and the information has not been able to make a thorough analysis so far.
