Table 4 Effect of AgNPs treatment on the activities of peroxidase and polyphenol oxidase (unit/g. Fresh wt./hour) in BBTV infected banana plants by ANOVA, compared with the control

From: Virucidal activity of silver nanoparticles against Banana bunchy top virus (BBTV) in banana plants

Treatments NPs conc.* (ppm) Antioxidant enzymes
POX (U/g FW) PPO (U/g FW)
Healthy control 1.245a 0.213a
Viral control 1.275b 0.253a
Nano-control** 50 2.645d 0.313b
AgNPs post-BBTV inoculation 40 2.540d 0.383c
50 2.826e 0.472e

L.S.D 0.028 0.038
  1. Values are the means of three replicates
  2. Means within the same column and treatment followed by the same letter are not significantly different according to Duncan (P ≤ 0.05)
  3. NPs conc.* = NPs concentration
  4. Nano-control** = The best concentration recorded the lowest of infection rate and non-toxic to the plants
