New Spectral Indices as Indicators of Carotenoids Content
View through CrossRef
Carotenoids play a key role in adaptation of plants to light stress and other unfavorable ecological conditions. Remote sensing of carotenoids content still not well developed due to the absorptions overlap of chlorophyll a and carotenoids in the visible spectral range. In this study, for accurate estimation of carotenoids contents, an assumption of absorption in [450, 550nm] is proposed. That is, the spectral reflectance features in this range are comprehensive effects of chlorophyll (chl) and carotenoids (car) absorption. And the effects of chlorophyll and carotenoids were multiplicative in [450, 550nm] and a new spectral index was defined. The results showed that the new spectral index was strongly related to carotenoids and could be applied as the indicator of carotenoids content.
