Influence of Rootstocks and Crop Load Ratios on Gibson Golden Delicious Apple Yield and Fruit Quality
Rootstocks and crop-load management are important factors that influence the profitability of apple orchards. Rootstocks influence tree vigor, precocity, sustained productivity, fruit size, and tree stress tolerance. Crop load affects fruit maturity, size and grade, and return bloom in the subsequent year. Modern high-density systems require careful selection of rootstocks and management of crop-loads to optimize yield and ensure a return crop for following seasons. This report summarizes the yield and fruit quality of Gibson Golden Delicious apple grown on a combination of different rootstocks and cropping levels during 2010.
