Infectivity assessment of hop plants (cv. Celeia) following biolistic inoculation of HLVd, CBCVd and HLVd + CBCVd.
| Treatments | Before Dormancy (4 mpi) | After First Dormancy (14 mpi) | After Second Dormancy | |||||||
|---|---|---|---|---|---|---|---|---|---|---|
| 28 mpi | 31 mpi | |||||||||
| Leaf Symptom | Plant Stunting | Bine Cracking | Leaf Symptom | Plant Stunting | Bine Cracking | Leaf Symptom | Plant Stunting | Bine Cracking | Green Plant Parts, Weight (g) x | |
| HLVd | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 135.9 a |
| CBCVd | 0 | 0 | 0 | 0.4 | 1 | 0 | 1 | 1 | 0 | 66.9 b |

The data represents mean value of 10 replicates for individual treatment (mock-inoculated, CBCVd or HLVd and CBCVd + HLVd viroid inoculation). Leaf symptoms (absent: 0; mild: 1; severe: 2); Stunting and bine cracking (present: 1; absent: 0) are represented as score. x Means followed by the same letter were not significantly different at the 5 % level (Duncan’s multiple range test).
