Abstract

Cannabis is an annual dioecious herbaceous plant native to Central Asia. Owing to its medicinal properties, laws regarding cannabis use have been liberalized worldwide, with many studies focusing on global cannabis cultivars. This study aimed to determine the optimal environmental conditions—light quality, relative humidity, and temperature—for cutting propagation of the cannabis cultivars ‘IT342810’ and ‘IT342811,’ developed by the Rural Development Administration of Korea. The results showed that the optimal light quality varied between cultivars, while high relative humidity consistently promoted adventitious root formation in both cultivars. The optimal rooting temperatures were 25–30°C for ‘IT342810’ and 20–30°C for ‘IT342811.’ Although this study focused on identifying optimal environmental conditions for Korean cannabis cultivars, the differing responses between the cultivars investigated here suggest that optimal conditions suggest depending on the genetic background of each cultivar.
