Cutting the tips off cannabis seeds – a process more formally called scarification – could shorten germination times and boost germination rates as cultivators are attempting to disinfect seeds, a new study determined.
Three researchers from the University of Guelph in Ontario, Canada, experimented on different cannabis genotypes to reach its conclusion.
The study also looked into the effect different types of disinfectants had on in vitro seed germination.
It found that soaking the materials in 4.6% sodium hypochlorite along with 0.008% hydrogen peroxide for almost 17 minutes resulted in the best outcome while still achieving zero contamination.
The study also stated that in vitro seed germination with scarification of cannabis and this disinfectant method could improve the efficiency of finding new cultivars and hunting for better genetics.
Are you a social equity cannabis license holder or applicant?
The MJBizCon team is now accepting 2023 Social Equity Scholarship Program applications.
The mission of this program is to provide social equity cannabis license holders or applicants access to the #1 global cannabis industry conference + tradeshow in Las Vegas.
Who can apply?
- Students currently enrolled in a cannabis-related program at an accredited university or college.
- Cannabis executives at licensed social equity cultivation, extraction/processing, retail, manufacturing/brand businesses (or awaiting application approval).
Don’t miss out on this potentially life-changing opportunity.

“Our protocols can be implemented to reduce contamination and increase the germination rate of large-scale pheno-hunting and breeding programs for this economically important crop,” authors wrote.
Aside from using a scalpel to remove the tip of the seed, the researchers also suggested that using sulfuric acid for scarification could be more efficient.
