RED COLOR DEVELOPMENT OF APPLE: A LITERATURE REVIEW

This study was commissioned by C. M. Holtzinger Fruit Co. in memory of Jim Campbell of Tieton, Washington. Jim was a consummate grower and loved the challenge of coaxing fruit from his trees. In the words of his son, Craig Campbell, “growing up on the farm in Tieton, my father Jim Campbell was always trying something new in either tree fertilization or foliar application to enhance quality and color in apples. I think his Hort schooling at WSU enabled him to understand the scientific side of growing, which encouraged the desire for growing better apples.”
