Early performance of 'Buckeye Gala' grafted on 13 apple rootstocks in Mexico.

摘要

The objective of this study was to evaluate 13 apple rootstocks grafted with 'Buckeye Gala' in an apple growing district of Chihuahua, Mexico. The trial was established in sandy loam soil, 0.8 m deep, pH 6.3, and organic matter content 0.53%. The planting distance was 4.5x2.5 m. Trees were pruned in winter and trained as vertical axis. The results showed that the rootstocks with better survival in this region were G.935, M26 NAKB, B.9 Europe, and B.9 USA. The rootstocks B.9, M9 T337, G.41, G.935, and G.11 showed low to medium vigor. The Geneva series (G and CG) had the highest accumulated yield and production efficiency after 7 years of the trial.
