Passion fruit (Passiflora edulis Sims f. flavicarpa DEG) is a tropical fruit widespread in Brazil, the largest producer and consumer in the world. As a climacteric fruit, it continues the ripening process after being detached from the plant, resulting in a short shelf life, with post-harvest problems, such as wilting and susceptibility to attack by microorganisms such as fungi. Therefore, this work aimed to develop chitosan-based coatings to be applied on passion fruit to maintain its post-harvest quality. Film forming solutions were prepared using chitosan (C) as the main polymer, carnauba wax (W) or rosin (R) as a hydrophobicity promoting agent and zinc oxide (ZnO) nanoparticles as an antimicrobial agent. The solutions were applied to passion fruit surfaces and the fruits were stored for 10 days at 22.5 °C and 82 RH for continuous evaluation. To determine the coating effect on ripening evolution during storage, the fruits were analysed for mass loss, texture, colour, pH, acidity, total soluble solids, and sugar contents. The post-harvest loss index was also determined during storage. The results showed that C + R coatings were more effective in protecting the fruits against weight loss, injury appearance and microorganism attacks. The visual appearance was also maintained. Increasing the resin concentration in the film forming solution provided better protection for the fruits against excessive weight loss and delayed the physicochemical changes related to maturation (acidity, pH, soluble solids, and firmness). Therefore, rosin-containing coatings provided the best results in postharvest applications to control passion fruit storage problems.

Acidic soils rapidly retain applied phosphorus fertilizers and consequently present low availability of this nutrient to plants. the use of phosphate-solubilizing microorganisms to help plant phosphorus (P) absorption is a promising sustainable strategy for managing P deficiencies in agricultural soils. Trichoderma strains have been one of the most studied filamentous fungi for improving the production and development of several crop species mainly due to their capability for symbiotic associations and their ability to control soil-borne plant diseases. Thus, this work sought to bioprospect Trichodermastrains from the Amazon rainforest capable of solubilizing/mineralizing soil phosphate and promoting soybean growth. Soybean plants inoculated with selected Trichoderma strains were cultivated in soil under greenhouse conditions and under a gradient of rock phosphate and triple superphosphate. As a result, 19.5% of the isolated Trichoderma strains were able to solubilize phosphate. In addition, those strains produced different organic acids during the solubilization process. Trichoderma spp. strains showed positive responses in the promotion of soybean growth?from 2.1% to 41.1%?as well as in the efficiency of P uptake-up to 141%. These results reveal the potential of Trichoderma spp. from the Amazon biome as promising biofertilizer agents. |
