Ongoing project
Investigating the control of fruit drop in mango to support innovative solutions for Australian growers (MG21004)
Delivery Partner: The University of Queensland
This investment is improving understanding of the molecular pathways regulating fruit abscission in mango, particularly the relationship between activation of the abscission zone, hormonal changes, and carbohydrate reserves leading to early fruit drop. Increased knowledge of changes in molecular signals that occur during early, mid and/or late fruit drop will enable more targeted application of plant growth regulators.
This project will validate the effect of plant growth regulators on fruit abscission and propose management strategies to minimise early fruit abscission. This information will support mango growers in making an informed selection in using plant growth regulators for fruit retention in Australian mango production systems.
This project is a strategic levy investment in the Hort Innovation Mango Fund
