ABSTRACT
Leaf nutrient content indicate the nutritional status of the tree, assist in fertilizer recommendation and may indicate incompatible scion/rootstock combinations in budded fruit trees. The objective of this study was to evaluate leaf nutrient contents of ‘Maciel’ peach budded on five rootstocks (‘Aldrighi’, ‘Capdeboscq’, ‘Flordaguard’, ‘Nemaguard’ and ‘Okinawa’). Two experimental orchards located in Pelotas, Brazil, were evaluated on the 2nd and 3rd years after planting, respectively in 2012 and 2013. We concluded that ‘Aldrighi’, 'Capdeboscq’, ‘Flordaguard’, ‘Nemaguard’ and ‘Okinawa’ rootstocks did not influence P and Mn leaf content on ‘Maciel’ peach scion, in both orchards and years of evaluation; ‘Nemaguard’ rootstock reduces Mg leaf content of ‘Maciel’ peach scion, but does not change the class of agronomic interpretation; although N, Fe, Zn and B leaf content were below than normal or insufficient in almost all samples from both orchards and years of evaluation, these studied rootstocks did not influence leaf nutrient interpretations.
