Experiment 3

Video: Introduction to Peach Crop load Canopy Experiment using Vertical Leader tree training

This experiment examines low, medium and high fruit crop loads on a 'Vertical Leader' tree training system to analyse the interaction between light interception and crop load on yield, fruit quality and fruit sweetness (brix).

Crop load and fruit position influence variability in nectarine quality

Consistent fruit size and high soluble solids concentration (SSC) in nectarines are important components of fruit quality and consumer acceptability.
