| Summary: | © Int. J. of GEOMATE. Plangoor Marian plum (Bouae burmanica) has a short harvesting period and usually harvested at fully ripe fruit stage .Therefore, the jelly-seed often occurred inside the fruit .The jelly-seed is a physiological disorder and causes fruit softening and wilting .This symptom will affect the storage period and shelf-life of the fruit .Jelly-seed also found after harvesting .This study was determined the activities of two important cell wall degradation enzymes which werepolygalacturonase (PG) and pectin methyl esterase (PME)from 3harvesting stages of plan go fruits 75, 85 and 95 days after full bloom )DAFB .(Fruits were storage at 10 and 25°C .It was found that the jelly-seed symptom only occurred in the 95 DAFB fruits after harvest and storage at 25°C .This fruits also had the highest activity of PG. The PG activity also increased with the ripening stages and storage period .The activity of PG and PME were delayed when storage at 10°C compared with those of the fruit kept at 25°C. |
