Abstract: (435 Views)
The reflectance spectrum in tree leaves depends on their pigments type and its concentration. Each species have unique spectrum that directly related to its pigments. UV-Vis Reflection spectroscopy offers a fast and nondestructive method for estimating pigments ratio in leaves. In this research three indices, including SIPI, ND and PSRI have been used to determine Cars/Chl ratio. The results show that a sharp decrease in the ratio of carotenoid to chlorophyll for olive leaf to about 172.4 times, orange to 27.7 times, and berry to about15.6 times.
