PROFILO ANTOCIANICO E ATTIVITÀ ANTIOSSIDANTE DEL SUCCO DI DIVERSE ACCESSIONI DI MELOGRANO
Aim of this paper was identify accessions of pomegranate with high anthocyanins and polyphenols content and correlate their values with antioxidant activity. Anthocyanin’s profile was determined by HPLC-DAD. Antioxidant activity was measured by fluorimetric assay and expressed by ORAC value. Results obtained was correlated and analyzed to find best accession.
Tree-to-tree variation in plant-based measurements as indicators of orange water status
A study was conducted in order to determine the sensitivity of measured indicators of the plant water status in a citrus orchard. In ten adult orange (Citrus sinensis) trees, grafted on sour orange (C. aurantium) rootstocks and drip irrigated every second day, sap flow by Granier TDP probes, leaf and xylem water potential, gas exchange and leaf and canopy thermal imaging were hourly monitored all over the day. The evaluations were performed during two separate clear-sky days with different environmental conditions, respectively in the summer and autumn seasons. Variations of environmental components (reference evapotranspiration, solar radiation, vapour pressure deficit and temperature) wer…
