  1. aDisease Symptom Score (DSS) estimated using an arbitrary 0–4 scale where 0 = no symptom, 1 = 0.1–1.0 cm systemic infection on vessels, 2 = 1.1–3.0 cm systemic infection on vessels, 3 = 3.1–4 cm systemic infection on vessels or soft rot on stem, 4 = inhibition of the germination and the growth. The visible symptoms first appeared on positive control plants
