Microstructure of peel cell wall and selected physico-chemical characteristics of 'Berangan' banana (Musa cv. Berangan [AAA]) ripened at high temperature
Peel of mature-green ‘Berangan’ banana (Musa cv. Berangan AAA) was investigated by scanning and energy filtering transmission electron microscopy. Fruits were ripened at 25ÚC and 37°C, and micrographs of the fruits were compared at three different stages of ripening namely green, turning yellow and...
