Destructive and optical non-destructive grape ripening assessment: Agronomic comparison and cost-benefit analysis.

PLoS One 2019 29;14(5):e0216421. Epub 2019 May 29.

Reliability and economic assessment of the Multiplex® optical sensor employed for non-destructive grape parameters estimates was evaluated in 2017 against a wet chemistry approach in mature vineyards including five cultivars (two whites, two red and one pink colored) assuring a broad range of variation in both technological and phenolic maturity parameters. Among the five Multiplex (Mx) indices evaluated (SFR_R, FLAV, FLAV-UV, ANTH_RG and FERARI) in all cultivars with the exception of Barbera SFR_R showed a significant and linear correlation with total soluble solids (TSS) for TSS ≥ 10 °Brix. Conversely, no significant correlation was found between FLAV and total flavonols concentration, whereas a significant linear correlation was found in Barbera (R2 = 0. Read More

Limitation of mineral supply as tool for the induction of secondary metabolites accumulation in tomato leaves.

Plant Physiol Biochem 2018 Sep 27;130:105-111. Epub 2018 Jun 27.

Institute of Crop Science and Resource Conservation - Horticultural Science, University of Bonn, Auf dem Huegel 6, 53121, Bonn, Germany.

Agricultural residues are natural sources for secondary metabolites as high value ingredients for industrial uses. The present work aims to exploit the accumulation potential of rutin and solanesol in tomato leaves following nitrogen and general mineral deficiency in a commercial-like greenhouse. Physiological responses of tomato plants were monitored non-destructively with a multiparametric fluorescence sensor, and biochemical parameters were determined by means of HPLC analysis. Read More
