Outline of Final Research Achievements

We developed a device to measure fluorescence spectra and images simultaneously excited by multiple wavelength (300 - 400 nm), and were successful in analyzing epidermal optical transmittance and fluorescence distribution in leaves nondestructively.
Ultraviolet-B irradiation to a peanut leaf caused optical holes on the leaf surface so that the transmittance in ultraviolet region increased exponentially. It’s shown that the monitor of the transmittance is extremely effective for the early detection and the quantitative evaluation of the UV-B impact to the plant leaves. Besides, seasonal variation of chlorophyll contents, anthocyanin contents and the epidermal transmittance were investigated in 30 kinds of trees. The results are that the epidermal transmittance characteristics of tree leaves differ according to both the species and the season, and are closely related to the photosynthesis activity and the pigments of leaves.
