Exposure of seeds to aerosol smoke or crude smoke extracts stimulates the germination of a number of fire-dependent and fire-independent plant species. We now report the identity of a germination-promoting compound present in plant- and cellulose-derived smoke. The structure of this compound, deduced from spectroscopic analysis and confirmed by synthesis, was shown to be that of the butenolide 3-methyl-2H-furo[2,3-c]pyran-2-one (1). Here we show that 1 promotes germination of a number of plant… Expand
Plant derived smoke stimulation for seed germination and enhancement of crop growth: A review
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, aExpand
Isolation of the major germination cue from plant-derived smoke
A highly active, heat stable, long lasting compound, 3- methyl-2H-furo[2,3-c]pyran-2-one (1), that stimulates seed germination was isolated from plant-derived smoke water using bioactivity-guidedExpand
More butenolides from plant-derived smoke with germination inhibitory activity against karrikinolide
Abstract Plant-derived smoke is known to play an important role in promoting germination in the post-fire environment, thereby stimulating regeneration of vegetation from the soil seed bank followingExpand
Formation of a seed germination promoter from carbohydrates and amino acids.
Evidence is provided for the formation of the major germination cue found in smoke from ubiquitously occurring organic compounds from reactions of sugars with amino acids. Expand
Germination and post-germination response of Acacia seeds to smoke-water and butenolide, a smoke-derived compound
It is confirmed that smoke generated from wildfires has the ability to stimulate seed germination and also to improve seedling vigour and this stimulatory characteristic of smoke has now been confirmed by the isolation of a butenolide from plant smoke that actively promotes germination of many plant species.

A butenolide, isolated from smoke, can overcome the detrimental effects of extreme temperatures during tomato seed germination
Results of the present study indicate the potential use of the butenolide compound in restoring normal seed germination and seedling establishment in tomato below and above optimum temperatures. Expand
A smoke-derived butenolide improves early growth of tomato seedlings
Insight is gained into the physiological events involved in seed germination and seedling development and which are affected by butenolide using tomato using cultivar “Heinz 1370” seeds to indicate that the butensolide is implicated in mobilization and utilization of stored reserve materials in developing tomato seedlings.

Effects of aqueous smoke solutions and heat on seed germination of herbaceous species of the Sudanian savanna-woodland in Burkina Faso
Six different concentrations of smoke solution were tested on 13 herbaceous species and the germination of a forb species, Borreria scabra, was significantly stimulated, indicating a specific requirement for the type and dosage of smoke treatments. Expand
Butenolide from plant-derived smoke enhances germination and seedling growth of arable weed species
It is found that while smoke stimulated germination in a number of species it also had negative impacts on other species, and butenolide was effective on the widest range of species in terms of enhancing germination percentage, rate and seedling mass. Expand
Effect of smoke derivatives on in vitro pollen germination and pollen tube elongation of species from different plant families.
Results indicate that plant-derived smoke and the smoke-isolated compounds may stimulate pollen growth in a wide range of plant species. Expand


The effect of a plant-derived smoke extract on the germination of light-sensitive lettuce seed
A simple and rapid bioassay using seeds of Lactuca sativa L. Grand Rapids for the detection of germination-enhancing compound(s) in plant-derived smoke extracts shows responsiveness to smoke-derived extracts over a wide concentration range. Expand
Smoke as a germination cue: a review
The positive effects of smoke have resulted in it being used as a seed pre-treatment for enhancing conservation of threatened or rare species, the horticultural exploitation of desirable plants and in the reclamation of mine spoils and disturbed land. Expand
Seed Ageing and Smoke: Partner Cuesin the Amelioration of Seed Dormancyin Selected Australian Native Species
Variation in success between the two methods confirmed earlier conclusions that substances contained in plant-derived smoke may be inhibitory at high concentrations for particularly sensitive species. Expand
A critical account on the inception of Striga seed germination.
Experiments have shown that the mechanistic connection between SXSg and the strigol D-ring is not valid, and therefore the proposed redox mechanism for the induction of Striga seed germination by strIGolactones does not hold. Expand
