ANTIOXIDATIVE ACTIVITY AND BER APPEARANCE IN PEPPER FRUITS UNDER INFLUENCE OF BIOSTIMULANT TREATMENT AND HYBRID

U ovom je istraživanju praćena antioksidativna aktivnost ploda paprike, ukupan i komercijalni prinos, broj nekomercijalnih plodova te pojava vršne truleži ploda pod utjecajem tretmana s biostimulatorima i hibrida. Statistički značajno najveća (P≤0,01) antioksidativna aktivnost, određena DPPH metodom, zabilježena je kod tretiranih biljaka paprike Century F1 te je bila u značajnoj pozitivnoj korelaciji (0,526*) s komercijalnim prinosom kod oba hibrida. Općenito, tretman s biostimulatorima pozitivno je utjecao na sve ispitivane pokazatelje kod hibridne paprike Century F1, dok je značajno smanjio pojavu nekomercijalnih plodova i vršne truleži kod Blondy F1, što je u konačnici dalo značajno veći komercijalni prinos kod oba hibrida.Anti-oxidative activity of pepper fruits, total and commercial yield, number of non-commercial and BER fruits under influence of bio-stimulant treatment and pepper hybrid were investigated in this experiment. Significantly highest anti-oxidative activity, determined by DPPH assay, was recorded in treated Century F1 hybrid pepper plants. Also, positive significant correlation (r=0.526*) between commercial yield and anti-oxidative activity appeared. Generally, treatment with bio-stimulants positively influenced all investigated parameters in Century F1 hybrid, while in Blondy F1 significantly decreased number of non-commercial and BER fruits. At the end, compared to untreated plants, treatment resulted in higher commercial yield in both hybrids
