8. Determination of pesticide residue levels in freshly harvested and processed lowbush blueberries

9. Effects of calcium salts and citric acid on the quality of canned lowbush blueberries

10. Investigation of preprocess changes (chemical, microbiological, and/or physical) that can lead to the development of a simple and inexpensive method to measure preprocess berry spoilage

11. The effect of fertilization and irrigation in blueberry fruit quality
