28. Post-harvest citrus diseases: Potential of the Lentinula edodes, Agaricus blazei, jasmonic acid, mesocarp (Citrus sinensis var. Valência) and epicarp (Citrus aurantifolia var. Tahiti) in the control and in the resistance induction / Doenças pós-colheita em citros: potencial do Lentinula edodes, Agaricus blazei, ácido jasmônico, albedo (Citrus sinensis var. Valência) e flavedo (Citrus aurantifolia var. Tahiti) no controle e na indução de resistência
Brazil is considered the biggest citrus producer and the biggest orange juice exporter. Post-harvest diseases represent a great loss in the citriculture, and for many fruits to be exported they should be free of chemical residues. In relation to some pathogens of importance in post-harvest it can be mentioned Guignardia citricarpa (black-spot-ofcitrus), Peni

32. Uso de solução conservadora e de películas comestíveis em maçãs da Cultivar Royal Gala minimamente processadas: efeito na fisiologia e na conservação / Use of conservative solution and edible coating in minimally processed royal gala cultivar apple: effect in physiology and in the conservation
One of the current proposals to increase the shelf life of the minimally processed (MP) fruits is the investigation of a material that is adherent to the cut surface of the fruit in order to minimize physiological, physico-chemical and microbial deteriorations. The goal of the study is to evaluate the effect of preservative solution and edible coatings in th

33. Honey bee attractants and pollination in sweet orange, Citrus sinensis (L.) Osbeck, var. Pera-Rio
This experiment studied the frequency and behavior of insects on sweet orange flowers, Citrus sinensis (L.) Osbeck, their effect on fruit production (quantity and quality), nectar and pollen collection, and the effectiveness of different attractants. Over three consecutive years, the most frequent visitor to the flowers was Apis mellifera (Africanized). Flow
