DETERMINATION OF ANTIOXIDANT ACTIVITY IN PEPPER FRUITS FERTILIZED WITH NATURAL BIOSTIMULATORS FORMED FROM SPORES AND MICHELIA OF TRICHODERMA ATROVIRIDE NON-GENETICALLY MODIFIED AND FULVIC ACID

Abstract

The aim of this study was to determine the role of fertigation with Trichoderma atroviride and fulvic acid at 6 varieties and a hybrid of long pepper (Capsicum annuum L.) var. longum. For this purpose, determinations were made on the content of total
polyphenols, ascorbic acid and antioxidant activity of peppers that have reached physiological maturity.
The determinations were made by the Folin-Cicâlteu method, by titration and the DPPH method. The results obtained in the samples fertigated with Trichoderma atroviride are superior to the samplesfoliarly fertilized with fulvic acid. Although there is a difference between them, we believe that it is appropriate to use both biostimulators in pepper culture.
