Exogenous application of melatonin, SA, and tJA on the bacterial population of Ca. L. asiaticus in HLB-infected Valencia sweet orange trees. CT of RT-qPCR for the detection of Ca. L. asiaticus in HLB-infected Valencia sweet orange trees after treatment with 200 mL of Milli-Q water (control), melatonin (0.1 mm), SA (0.1 mm), or tJA (0.1 mm) through foliar application is shown. Whiskers indicate the minimum and maximum values of the data, horizontal thick lines show the medians, black dots indicate the raw data, and boxes show the interquartile ranges (25th to 75th percentiles of the data). Different letters indicate statistically significant differences among varieties, while the same letter signifies no significant differences between them using Tukey’s HSD (P < 0.05).
