| Abstract: | Leaf disks from hop stunt viroid (HSVd)-infected cucumber plants and healthy controls were cultured in vitro under different auxin/cytokinin regimes. Amounts of tissue growth and root formation were consistently reduced as a result of HSVd infection. Histological observations indicated that anomalies in the distribution of peripheral meristems and tracheary elements associated with cambial cells might be involved in the hypoplastic syndrome incited by HSVd. |
