The definition of the minimum O2 levels required to maximally inhibit fruit aerobic respiration is essential to efficiently delay ripening and senescence during long-distance transportation. The aim of this study was to determine the minimum O2 levels required to maximally inhibit the aerobic respiration and prolong the post- harvest life of ?Tommy Atkins? mangoes produced during the summer, winter and spring growing seasons in the S ?ao Francisco Valley (SFV), Brazil. For the identification of the minimum O2 levels, mangoes were stored for 42 days at 9 ?C and 90?95% RH. The change from aerobic to anaerobic metabolism was weekly determined based on the levels of O2, CO2 and ethanol production inside hermetically closed containers containing fruit samples. The minimum O2 levels required to maintain aerobic respiration of mangoes produced in the summer, winter and spring changed from 0.25 to 13.75 kPa, 0.80 to 2.30 kPa and 1.42 to 17.40 kPa, respectively, as the storage duration increased. In order to validate the minimum O2 levels to maintain fruit aerobic respiration and quality, ?Tommy Atkins? mangoes produced in the SFV were harvested at the commercial maturity in the winter growing season in 2022 and were stored under dynamic controlled atmosphere (DCA) conditions with the minimum O2 levels determined with fruit produced in the same growing season in the previous year, 2021. Fruit stored under DCA were compared to fruit stored in refrigerated atmosphere (RA) for 60 days at 9 ?C and 90?95% RH. The minimum O2 levels used in the DCA effectively inhibited fruit ripening, controlled black flesh and reduced rot incidence during 60 days of cold storage and 60 + 7 days of shelf life.

Endophytic microorganisms have a wide genetic diversity, being very useful for agriculture, for producing growth regulators and making nutrients available to plants. In this context, this research aimed to isolate and characterize endophytic bacteria from bamboo Guadua sp., in order to evaluate the use of these microorganisms in promoting plant growth in yam plants (Dioscorea rotundata Poir). For this, the macromorphological characteristics of bacterial colonies were studied: shape, borders, consistency, color, brightness. Micromorphological analysis was performed using the Gram method. Biological tests of phosphate solubilization, biological nitrogen fixation and indole acetic acid production were carried out, where the bacteria with the best results were selected to assess the potential to promote the growth of white yam plants. The growth experiment consisted of four treatments: a control (without inoculation) and three treatments with endophytic bacteria, inoculated in pre-acclimated yam plants. Each treatment consisted of 6 repetitions with 5 plants per plot, totaling 30 plants per treatment. The colonies showed similar patterns of morphological characteristics for the three collection sites, with characteristics such as 'circular' shape, 'entire' border, 'creamy' consistency, 'brown' color and 'bright' shine. We observed that 39.1% of the bacteria were able to perform phosphate solubilization, 61.9% performed atmospheric nitrogen fixation and 26.9% performed indole acetic acid synthesis. The results showed that the endophytic bacteria isolated from Guadua sp. did not promote dry matter accumulation of white yam plants after 45 days of cultivation in a nursery.
