Reflectance spectra in the visible and near infra-red range of the spectrum, acquired for maple (Acer platanoides L.), chestnut (Aesculus hippocastanum L.), potato (Solanum tuberosum L.), coleus (Coleus blumei Benth.), leaves and lemon (Citrus limon L.) and apple (Malus domestica Borkh.) fruits were studied. An increase of reflectance between 550 and 740 nm accompanied senescence-induced degradation of chlorophyll (Chl), whereas in the range 400-500 nm it remained low, due to retention of…

Non-Destructive Estimation Pigment Content Ripening Quality and Damage in Apple Fruit with Spectral Reflectance in the Visible Range

Modern non-destructive optical-reflectance-based techniques for estimation of pigment (chlorophyll, carotenoid, anthocyanin, and flavonol) contents, the rate of onand off-tree ripening as well as for


During fruit ripening, chlorophyll degradation is responsible for the degreening of the ground color, which is a well-established ripeness indicator for several species. In completely red-pigmented

Optical Properties and Nondestructive Estimation of Anthocyanin Content in Plant Leaves¶

Absorption and reflectance spectra of maple, cotoneaster, dogwood, and pelargonium leaves with a wide range of pigment content and composition were studied in visible and near-infrared spectra to reveal specific anthocyanin (Anth) spectral features in leaves.

Leaf optical properties in higher plants: linking spectral characteristics to stress and chlorophyll concentration.

The optical response to stress near 700 nm, as well as corresponding changes in reflectance that occur in the green-yellow spectrum, can be explained by the general tendency of stress to reduce leaf chlorophyll concentration.

Physiological foundations of spectral imaging-based monitoring of apple fruit ripening

The previously developed plant senescence reflectance index (PSRI) is proposed, which is closely related with carotenoid-to-chlorophyll contents ratio in fruit and hence with their ripening and provides for a robust recording of apple ripening both on tree and in storage yielding data sets comparable across orchards and growing seasons.

A satellite-based modified plant senescence reflectance index for green-water drought monitoring

The present research introduces a satellite-based plant senescence reflectance index (PSRI2) involving in its calculation two red edge bands (0.705 μm and 0.783 μm) and the green peak band (0.560 μm)



Light-induced pigment degradation in leaves and ripening fruits studied in situ with reflectance spectroscopy

It was found that the sensitivity of plant pigments to photobleaching increases as ripening progresses in lemon fruit, and some features of reflectance spectra in the bands of chlorophyll and carotenoid absorption were found to be suitable for the differentiation of photo-induced pigment breakdown from the transformation of the pigments taking place during senescence.

Signature Analysis of Leaf Reflectance Spectra: Algorithm Development for Remote Sensing of Chlorophyll

Photosynthesis and Chlorophyll Fluorescence Characteristics in Relationship to Changes in Pigment and Element Composition of Leaves of Platanus occidentalis L. during Autumnal Leaf Senescence.

Data indicate that the efficiency for photochemical energy conversion of the remaining functional components was maintained at a high level during the natural course of autumnal senescence, and are consistent with previous studies which have characterized leafsenescence as being a controlled process.

Remote estimation of chlorophyll content in higher plant leaves

Abstract Indices for the non-destructive estimation of chlorophyll content were formulated using various instruments to measure reflectance and absorption spectra in visible and near-infrared ranges,

Anthocyanin, Carotenoid, and Chlorophyll Changes in the Peel of Cox’s Orange Pippin Apples during Ripening on and off the Tree

The concentrations of various peel pigments of Cox's Orange Pippin apples have been measured during ripening on the tree and during storage at 12 °C and there was no consistent or marked difference in the rates of destruction of chlorophylls a and b.
