DRY-MATTER DISTRIBUTION OF 3 PEACH GROWTH TYPES

Our objective was to evaluate the dry-matter partitioning between the roots and shoots of two genetically size-controlled peach [Prunus pers ica (L.) Batsch] types, dwarf and pillar, compared to a full-sized sta ndard peach type. Compared to the pillar and standard types, the dwarf type had a reduced leaf: root ratio, less allocation of dry matter to woody tissue and more to leaf tissue. Genetically size-controlled pea ch trees have a smaller root system, but a lower leaf: root ratio and may require modified soil and water management techniques to ensure hi gh productivity.
