Completed project
Improving consistency of soluble solids concentrations in summerfruit (SF11000)
Publication date: February 11, 2014
Delivery Partner: University of Western Sydney
Consistent fruit size and high soluble solids concentration in peaches and nectarines are important components of fruit quality and consumer acceptability. A high degree of variability within trees can be a major impediment to meeting consumer and export market requirements for consistent quality.
This project investigated factors influencing variation in fruit quality within trees and how it can be improved through tree management and fruit thinning.
Key findings included…
Some variation in soluble solids concentration is yet to be explained, requiring more research.
Findings suggest that growers can improve the consistency of fruit quality by managing trees to achieve a more uniform leaf-to-fruit ratio, conducting earlier fruit thinning, and using light enhancing tree training systems such as Spanish open vase.
