Schematic representation of the progression of capitate trichome development and senescence in cannabis genotypes MD and SQ based on the observations made in this study. The proportion of stalked-capitate trichomes increases exponentially with time in the flowering period to a maximum at 8 weeks. The process of glandular head dehiscence, secretion of resin and senescence begins at around 5 weeks and progresses to harvest (8 weeks). The timelines depicted here will vary by genotype as well as environmental conditions that impose stresses on the plant, which could accelerate the process of glandular head dehiscence and senescence
