The present work is devoted to application of spectroscopic method to investigation of biological objects. In this paper we measured absorption spectra of plant leaves on different stages of growth. The experiments showed that the youngest leaves have a maximum leaf absorptance and the maximum absolute quantum yields. As result of one way Anova we found significant difference of leaves absorption on four development stages.
