Viroid Analytical Testing
Determination and quantification of viroids (HLVd, LCV, and CCV)
Viroid testing aims to identify and remove infected plants that will decrease yield. By removing mother plants that are infected, the direct benefit will be reaped in the following cycles as each greenhouse’s efficiency is maximized.
Therefore, testing is most effective when performed routinely every 2-3 weeks to ensure the next cycle of clones is all HLVd-free, thus increasing yield.
Viroids
What are viroids?
Viroids are small, infectious RNA molecules that can affect cannabis plants, causing diseases and affecting the quality of cannabis products.
HLVd (Hop Latent Viroid), is a small, circular RNA molecule. It belongs to the family Avsunviroidae. Unlike viruses, viroids lack a protein coat and are composed solely of RNA. HLVd specifically infects hop plants.
Lettuce Chlorosis Virus (LCV) is a linear, single-stranded positive-sense RNA virus and a member of the Crinivirus family. Cannabis and hemp plants that are infected early will suffer stunted growth but may not show visual signs until a few weeks into flowering.
Cannabis Cryptic Virus (CCV) is a double-stranded RNA virus and a member of the Partitiviridae family.
