Chlorophyll content research using spectroscopic and laser-induced fluorescence techniques

The comparative research of the chlorophyll contents for a number of arboreous plants has been carried out using traditional spectrophotometric and fluorescent laser techniques. Seasonal changes are analyzed in the net chlorophyll content during the sprint-summer period for coniferous and deciduous wood plants, The changes in the chlorophyll contents due to needles and leaves fading are observed. The experimental results are obtained using the spectrophotometric and lidar techniques to study the seasonal dynamics of chlorophyll and pigment complex destruction in the course of needles and leaves fading. Analysis has shown that the results obtained different methods are identical.
