Table 3. Comparison of several parameters between asymptomatic and symptomatic cuticles.

Parameters	Cuticles from asymptomatic leaves	Cuticles from symptomatic leaves
Ct value	35.6±0.66 a	26.30±1.36 b
Isolation time (days)	5.5	14
Sucrose content (μg/g)	328.46±53.13 b	427.56±24.92 a
Fold change in pectinase activity c	1.29±0.06 a	0.97±0.07 b
Inhibition zone diameter (mm) d	4.13±2.27 a	1.54±1.05 b

All data were analyzed by Duncan’s multiple range test using SAS software package. Different letters represent significant difference at a level of p ≤ 0.05.

^c Fold-change in pectinase activity of cuticles isolated from HLB-asymptomatic and symptomatic leaves.

^d Inhibitory zone diameter of cuticles treated with a 500 mg/L ampicillin solution.
