Activity of cell wall degrading enzymes in hylocereus polyrhizus
Changes in the activities of cell wall degrading enzymes such as pectinmethylesterase (PME), polygalacturonase (PG), pectate lyase (PL) and cellulase were studied in red fleshed dragon fruit, Hylocereus polyrhizus harvested at three different harvest maturities. PME activity increased in fruit harve...

| description | Changes in the activities of cell wall degrading enzymes such as pectinmethylesterase (PME), polygalacturonase (PG), pectate lyase (PL) and cellulase were studied in red fleshed dragon fruit, Hylocereus polyrhizus harvested at three different harvest maturities. PME activity increased in fruit harvested earlier as opposed to fruit harvested at ripe stage while PG activity increased in all three different stages. Activity of pectate lyase was almost invariable in all three different stages. As for younger fruit, the cellulase activity increased progressively while activity was found to be within the same range in fruit harvested at ripe stage. |
