A possible role of hormones in growth and development of apple trees and a suggestion on how to modify their action


, : A possible role of hormones in growth and development of apple trees and a suggestion on how to modify their action. Acta Horticulturae (80): 457-464

The levels of endogenous auxin, gibberellins and cytokinins were determined at different times during vegetative growth in young pruned and unpruned apple trees. The total level of all compounds was generally higher in pruned trees. The cytokinin level was highest in conducting tissue in the trunk at the start of growth and it was twice as high in pruned as in unpruned trees.
