Understanding and Managing HOP latent viroid in cannabis - Zamir Punja, PhD [Video]. YouTube.    • Understanding and Managing Hop Latent Viro...   Looks Can Vary Two cannabis plants infected with the same viroid can have a wide degree of different visual symptoms. To catch it early does take a trained eye. Stage of Development Has an Impact What symptoms you may see are in part dependent on the stage of development of the plant and when (and where physically on the plant) the point of infection may have occurred. Common Symptoms Slow growth (stunting via shorter internode spacing) Leaf malformations Leaf chlorosis Can mimic iron deficiency Brittle stems Reduced root formation Horizontal growth that then grows up like an exponential curve Greater leaf overlap Reduced water intake *Flower destruction (smaller and less dense = reduced yield) Stem/Node Swelling Confirmed Case of HLVd May not commonly reported, but does happen Can Vary Greatly in the Plant This is why when sampling different portions of the plant should be taken. Special attention to the roots as HLVd can initially accumulate in this area. Can Vary By Cultivar While no cultivars have been show to be completely resistant to HLVd, there are some early data indicators that some may be more tolerant. This could be potentially used as part of a breeding program is this can show consistency. Trichome Change Reduced in size and shape This directly impacts the compounds that the plant can produce The numbers of trichomes are the same (top image) but the structure is what is different The infected trichomes are underdeveloped Impact Varies by Cultivar Unfortunately it is really a matter of how much is the plant cannabinoids reduced.
