Assessment of Ultraviolet Impact on Main Pigment Content in Purple Basil (Ocimum basilicum L.) by the Spectrometric Method and Hyperspectral Images Analysis

This research is aimed at the assessing impact of ultraviolet radiation in A, B, and C ranges (as additives to main light) on general plan condition, stress experienced by them, pigment concentration leaves leaf reflective characteristics. Under studying, there were photo-protective reactions purple variety basil plants. The plants grown plastic pots a phyto-chamber equipped with an automatic microclimate system. was divided into four compartments where, addition lighting, installed additional LEDs emitting their UV-A, UV-B, UV-C. Plant evaluated contents pigments as detected spectrometric method. Then correlations revealed between those values vegetative indices obtained based hyperspectral images. A strong correlation (R2 ? 0.83) observed ARI mARI anthocyanins leaves. weak = 0.0479) found carotenoids index CRI700, which attributed shielding effect anthocyanins. Deviations results are influenced surface unevenness, its thickness density. Additional needed including developing reflection taking account pigments.
