Abstract

By using a new kind of single-beam normalized photo-acoustic tomography spectroscopy (PAS-CT) technology with non-damage detection, the photo-acoustic tomography spectrum, optical absorption properties and photosynthetic pigment content of the green and yellow leaves of Dracontomelon duperreanum were studied. The photo-acoustic tomography spectrograms, obtained from different chopping frequency and sample translocation, were perfectly conform to each layer of cell’s optical absorption properties in Dracontomelon duperreanum leaves. The results showed that: the more photosynthetic pigment content the leaves of Dracontomelon duperreanum contain, the bigger optical absorption coefficient and the higher photosynthetic efficiency they have. In the research, we could find that the photosynthetic pigment content of the green leaves of Dracontomelon duperreanum is higher than that of the yellow ones. As a result, the optical absorption coefficient and the photosynthetic efficiency of the green ones were higher than the yellow ones. The photo-acoustic tomography spectroscopy could be a kind of non-damage detection to confirm the growth of trees. According to the results of our research, the photosynthetic efficiency of Dracontomelon duperreanum could be improved and its growth time could be effectively controlled. And it provides foundations to cultivate Dracontomelon duperreanum effectively. Furthermore, it could make benefits to the controlled environmental forestry and increase forest production to meet the need of forest for 7 billion people. The research showed high science value to the study and application of the photosynthesis of plants.
