ABSTRACT Colombia exported 5,912 t of Tahiti lemons to the United States and the Caribbean in 2015, where the production was reduced by the presence of citrus greening or Huanglongbing disease. During this study the physicochemical characteristics of the fruits from six rootstocks: Sunki x English, Volkameriano, Kryder, Cleopatra, Citrumelo and Carrizo were evaluated at different intervals up to 60 days at the conditions of Bogota, Colombia without refrigeration. Data analysis using ANOVA followed by post-hoc test LSD (α=0.05). The analysis demonstrated that all the rootstocks exceeded the export market expectations for all the clones: equatorial diameter (4.68±0.22 to 5.56±0.22 cm), fruit weight (64.28±4.95 to 103.91±6.43 g), color (dark green or light green), juice percent (> 27% of fruit weight), citric acid percentage (< 5%) and firmness (< 0.22065 kPa). The evaluated rootstocks comply with the export standards and retain their physical and chemical characteristics during the storage until 30 days after harvest (DAH), standing out "Kryder" that preserves them up to 45 DAH. Anticipating harvest 1, 3, 6 and 9 days before the timing of the commercial harvest, has no additional effects on the quality of the fruits and does not prolong the storage time.
