The objective of this research was to carry out an analysis of growth and physicochemical changes in cv. Anna apple in the Colombian high-altitude tropics using on the accumulation of growing degree days (GDD). Fruit samplings were taken every 15 days after anthesis (DAA) until harvest at 100 DAA (892.37 GDD). The dry and fresh weight and the equat...

... background color index of the epidermis increased as a function of time, going from a value of -7.99±0.1 at 159.61 GDD to -5.12±0.29 at 892.37 GDD. The color index of the pulp also increased throughout the development of the fruit, from a value of -5.61±0.293 at 159.61 GDD to -3.311±0.317 at 892.37 GDD (Fig. 4). The epidermis of the fruit is red where it receives sunlight and yellow on the opposite side (Campos, 2013). The background color was measured since the red color of the coating is not a good indicator of ripening. The results indicated that, as fruits progress in development, the coloration of both the epidermis and the pulp ...

The article proposes a biological method based on the use of gas-selective track membranes to form a modified gas atmosphere, considering the respiration rate of fruit. The work aims to study the change in the respiration rate of apples depending on the variety and storage time to substantiate the formation of the gas medium composition depending o...
