Abstract. The extracts of wild grapevines (Vitis) leaves (EHVS) from three accessions (P-178, E-200 and TN-4) at 6, 8 and 12 % v/v, were tested in vitro to evaluate their inhibitory effect on Botrytis cinerea development. Resveratrol (RVS) (60, 90, 120 µg/mL), citrus extracts (EC) (3, 5 and 8 % v/v) and cyprodinil + fludioxonil (SW) (500, 800 and 1000 µg/mL) were compared against EHVS. In average, SW presented inhibition of mycelial growth (ICM), sporulation (IE) and spore germination (IGC) (88.9; 85.5 and 93.7 %, average respectively). RVS presented the second higher inhibition rate. All EHVS presented antifungal activity; specially, P-178 at 12 % resulted in 72 % ICM, 75 % IE and 62 % IGC. This dose contained phenolic compounds 19.9 mg/mL, RVS 1.7 mg/mL, gallic acid 3.8 mg/mL and ferulic acid 2.5 mg/mL.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
