Production of ethylene by the C. delgadii stipe and internode explants at 1, 4, and 6 h after sample dissection. The production was stabilized between 4 and 6 h after explant excision. Therefore, the results obtained after 6 h were used for further analyses. Values represent the means ± standard deviation (SD) of 6 independent replicates. The Student’s t-test was used to estimate statistical significance of results. Data followed by different letters (a, b) were significantly different at p < 0.05.
