This research project will focus on development of science-based recommendations on the effectiveness of new apple rootstocks.

Project Objectives

  • Measure the precocity and performance of new size-controlling rootstocks and to compare these against industry standard;
  • Determine rootstock effects on calcium disorders, whole tree physiology, and fruit storage potential;
  • Assess the productivity of more vigorous rootstocks with a close examination of graft union compatibility.
