Spectrometric method for measuring light absorption by plant leaves

Abstract

This article describes the development of the experimental setup for researching the plant leaves absorption spectrum and its biological testing. The spectrometric method based on measurement of tissue optical properties by means of double-integrating-sphere system. During the study of light absorption by lettuce leaf it was noted that the total absorption of living and freshly cut leaf is identical, but changes over time after the cut. The »absorption map» of the lettuce leaf surface was compiled.
