Carolina Torres and Rene Mogollon have attended the ASHS 2022 annual conference in Chicago, Illinois.
Our lab members shared some of the results of this season’s research.
Dr. Torres talked about how packaging conditions majorly affect the development of lenticel breakdown (LBD) in apples. She showed the correlation between postharvest water chemistry (carbohydrate, metals and minerals content, pH, ORP, conductivity, temperature, turbidity, COD, and free chlorine) during packaging over LBD development in commercial fruit lots throughout the storage period.
The results showed phosphorus accumulation in the water positively correlated with high LBD incidences. Calcium, Boron, and Potassium may also be playing a role in the disorder’s expression. Finally, high free chlorine was not correlated with fruit with high LBD incidence.
On the other hand, Dr. Mogollon presented a novel way to obtain an early prediction of postharvest sun-stress disorders in Granny Smith apples. Using Hyperspectral images and Chlorophyll and Carotenoids related wavelength, he modeled the incidence of sunscald after 6 months of storage using data collected before symptoms were present. These results showed the feasibility of hyperspectral imagers for identifying sun-stressed fruit at harvest that may later develop sunscald symptoms during the cold chain.
Well done, team!
See you next year at the ASHS 2023 in Orlando, Fl.
