Aiming to extend its postharvest life, the objective of the work was to evaluate different concentrations of the commercial product based on carnauba wax in the postharvest longevity of Strelitzia juncea and Strelitzia reginae leaves. The experiment was conducted in a completely randomized design with five treatments and six repetitions, with one leaf per repetition for each species. The concentrations used were: 0% (control), 2%, 20%, 40% and 100%. The loss of leaf mass (%) and the visual quality of the leaves were evaluated through the criterion of notes, in addition to making use of anatomical analyzes of the stomatal structures of the leaves through scanning microscopy. The loss of mass was reduced with the increase of the wax concentration, however, high doses provided increased loss. The use of carnauba wax proved efficient at concentrations of 20 and 40%, maintaining the commercial quality of the leaves of S. reginae and S. juncea until the 24th day, while in the control treatment, the leaves maintained a commercial pattern until the 16th for S. reginae and 18th day for S. juncea. The deposition of wax in the stomatal structures may have influenced the loss of mass of both species as observed by scanning microscopy.</p>}, journal={Comunicata Scientiae}, author={Baudraz de Paula, Jean Carlo and Bonfante Rosalem, Isadora and Ribeiro Júnior, Walter Aparecido and Shimizu, Gabriel Danilo and de Faria, Ricardo Tadeu and de Andrade Pacheco, Camilla and Gonçalves de Oliveira Junior, Admilton}, year={2021}, month={May}, pages={e3421} }
