“…Physiologically: Smoke can also stimulate flowering, root initiation (Taylor and van Staden, 1996) and seedling vigour (Baxter and van Staden, 1994;Sparg et al, 2005). It enhances the germination and seedling vigour of Agricultural, Horticultural, Forage and Forestry seeds.…”

Smoke is an important factor involved in fire and post fire germination cues. The role of smoke in stimulating germination was first highlighted in South Africa in a study on Audouinia capitata, a threatened fynbos species. Farmers throughout the world have traditionally used fire and smoke in grain drying practices. It is thought that these methods improve germination and seedling vigor. Smoke has been applied in agriculture mainly by two ways viz., Aerosol method and Smoke water method. In aerosol method, seeds were directly exposed to smoke generated from burning plant material. Smoke-water is one of the most convenient means of application. The biologically active compounds present in smoke readily dissolve in water and when this smoke-extract is used as a diluted solution, treated seeds of many species show a marked improvement in germination. The main active germination compound of smoke-water derived from burned plant materials and cellulose has been identified as butenolide [3-methyl-2H-furo (2, 3-c) pyran-2-one], which is effective at very low concentrations (1 ppb). The compound has recently been referred to as "karrikinolide". Following the initial isolation of KAR1, a whole new family of plant growth regulators, termed 'karrikins', were identified in smoke and several related compounds have been synthesized. It is estimated that between 2 and 5 g of KAR1 is more than sufficient for 1 ha of land application rates that are commercially viable. Application of smoke in various agricultural, horticultural forage and forestry crops had found that smoke acted as a cue for breaking seeds of dormancy, improve seed germination, seedling growth, flowering, plant biomass of different plant families, Invitro plantlet regeneration and pathogen control (Anti-microbial properties).

“…Exposure of the seeds to short periods of far-red light overcame the stimulatory effect of the extracts. Both gibberellins and cytokinins are known to break the dormancy of Grand Rapids lettuce seeds [6], hence it is of interest to investigate whether smoke-derived extracts operate in a similar manner to either or both of these groups of plant hormones. The celery seed system [9] provides a tool for examining this aspect and also the relationship between red-light and smoke effects.…”

Seed dormancy of a highly-dormant cultivar of celery (Apium graveolens L.) was broken by combinations of plant-derived smoke extract or N6-benzyladenine (BA) and gibberellins Ad/y (GA4/7) in the dark at temperatures between 18 and 26 'C. A less dormant cultivar which responded to GA4j7 alone showed no additional response to smoke extract or BA. Neither smoke extract nor BA affected either cultivar in the dark in the absence of GA4i7. The partial dormancy-breaking effect of short exposures to red-light was also enhanced by smoke extracts in this highly-dormant cultivar. The results suggest that smoke extracts act in a similar way to cytokinins, by enhancing gibberellin activity in the celery seed system.Abbreviations: BA = N6-benzyladenine; GA417 = A4 and A7 gibberellin mixture.
