Jacaranda trees are common in urban areas of Valle de Mexico and often grows under nutritional and water stress conditions, which affects its growth. The supply of carbohydrates through the vascular system has recently been recommended as an option to improve growth and vitality. Therefore, the objective of this work is to assess the effect of glucose injected to the trunk of Jacaranda mimosifolia trees.in for concentrations: 0 (control), 30, 55 and 80 g L-1. Diameter (cm) and height (m) increments were determined, the canopy condition and foliage production were monitored and the content of carbohydrate in shoots, trunks and roots as well as the chlorophyll fluorescence (Fv/Fm). Significant differences were found (P≤0.05) in the increase in diameter and height with the application of 80 g L-1 glucose. The crown condition showed significantly higher values in density and lower in transparency, as well as an adequate foliage production, with the highest concentration (80 g L-1). Carbohydrate content showed significant differences (P≤0.05) in trunk, not in buds, roots, or chlorophyll fluorescence. The injections of glucose to the trunk have a significant effect on the growth of Jacaranda trees and affecting vitality to a lesser extent.
