Abstract
SummaryValencia orange trees grafted on Poncirus trifoliata and Troyer and Carrizo citranges were inoculated with budline tissue from dwarf orange trees. One of the budlines (033) caused a typical exocortis response on Etrog citron (Citrus medica) as well as scaling on P. trifoliata. Another four budlines came from trees on P. trifoliata showing dwarfing but no butt scaling. Tree size, yield, yield components and fruit quality were measured following planting out and cropping. The rootstock and the 033 budline inoculation combined to reduce 14-year-old trees on P. trifoliata to 18% of the size of uninoculated citranges. Inoculating the citranges with budline 033 reduced tree size by nearly 50%, and non-scaling inoculations reduced citranges to the same sizes as uninoculated trees on P. trifoliata (77% of uninoculated citrange). Reduced tree size resulted in fewer fruit per tree, but fruit quality was generally unaffected by inoculation. Yield per ha was closely correlated with canopy surface area per ha for all rootstocks, scions, inoculations and densities. The results show the dwarfing budlines used in these experiments induced a wide but predictable range of dwarf trees.
