Storage life can be prolonged with
pre-harvest treatments on the tree or postharvest pre-storage
treatments. The ethylene inhibitor AVG (aminoethoxyvinylglycine)
used is a common pre-harvest treatment and calcium, heat treatment,
polyamines, jasmonates and 1-MCP (1-methylcyclopropene)
treatments are the other common postharvest pre-storage treatments
for plums (Singh and Khan, 2010)
