- Abstract
- Creeping sage (Salvia sonomensis Green), a semi-shrub, is useful for plantings to reduce fire hazard and to stabilize soil. The most effective, practical and lasting technique to break seed dormancy was a soaking in gibberellic acid under constant agitation at 500 p.p.m. for 4 hours. Lesser concentrtions of this acid and shorter soaking periods were satisfactory if the seeds were planted soon after treatment and if soil mositure and other conditions fvored germination, Sulfuric acid, thiourea, hydrogen peroxide, hot water, and gibberellic acid slurry - used alone or in various combinations - were not as effective as the gibberellic acid soak and, in some instances, seriously damaged the seed.
