Studies on the relationship between trunk growth, yield and climatic factors in pome fruit


, : Studies on the relationship between trunk growth, yield and climatic factors in pome fruit. Untersuchungen uber den Zusammenhang zwischen Stammzuwachs, Ertrag und Witterungsfaktoren bei Kernobst: 129

Twenty- to 22-year-old trees of 7 apple cvs on M.1, M.2, M.4 and M.11 rootstocks and 12-year-old trees of 3 pear cvs on seedling and Quince A rootstocks were studied. Annual yields and average monthly temperatures and precipitation were taken from records and trunk growth was assessed by measuring annual rings. Yield was correlated positively and width of the annual ring negatively with tree age.
