Potencial para o biocontrole de Botrytis cinerea por leveduras em sistema integrado de cultivo de lírio

摘要: The objective of this study was to compare a population phylloplane yeasts in lilies cultivated conventional cultivation system other an integrated system, as well evaluate the antagonism Sporidiobolus pararoseus Botrytis cinerea. yeast community estimated by spore-fall method lower, middle and upper thirds plants, abaxial adaxial leaf surfaces. high on discs plants from it higher surface leaves third plants. To antagonism, concentrations 105, 106 107 cells mL-1 were sprayed three inoculation times: 24 hours before; simultaneously; after with B. cinerea at concentration 104 spores mL-1. incidence percentage disc tissue area colonized sporulation evaluated through category scale, starting fourth day inoculation. All reduced comparison control, most effective.
