The peach (cv. September Sun) and nectarine (cv. Rose Bright) rootstock experiments are investigating the impact of three crop loads (high, medium and low) across 5 different rootstocks examining effects on yield, distribution of sugars (brix content), maturity and fruit quality.

Time series videos

Every few weeks photos were taken of each experiment, and produced into a video to show the resulting growth of tree canopies and fruit development.
