Research Overview

Program Overview

The primary objectives of the pomology program are to investigate factors that determine yield and fruit quality of tree fruit crops, as well as environmental issues surrounding tree fruit production. Experiments include investigating the use of new, dwarfing peach and cherry rootstocks, irrigation scheduling, plant bio-regulators, and new methods to thin peaches, We are also interested in understanding the physiological basis for rain-Induced cracking of sweet cherries.

Program Objectives

  1. Science-based performance of various rootstock/scion combinations under different orchard, environment and management systems.
  2. Orchard management practices to improve production efficiency, profitability, and fruit quality
  3. Use and physiology of plant bioregulators to regulate cropping, improve production efficiency and fruit quality
  4. Mineral nutrition and soil management effects on fruit quality and tree growth
  5. Beneficial use of organic and inorganic amendments for reducing soil-borne disease and herbicides and improving fruit quality and plant health
  6. Fruit tree water relations, crop response to micro irrigation, and water conservation measures physiology
