Creator:: Oregon State University. Extension Service, Washington State University. Extension, University of Idaho. Extension, Long, L. E. (Lynn Edwards), 1953-, and Pacific Northwest Cooperative Extension
Abstract:: Tree vigor is important because more leaves mean more carbohydrate production and larger cherries. The production of high-quality cherries requires a gross canopy leaf area-to-fruit ratio of at least 200 cm2 of leaf area per fruit, which roughly translates to five leaves per fruit. Trees with a lower LA:F ratio...
