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… 
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, a
Formation of a seed germination promoter from carbohydrates and amino acids.
TLDR
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.
A smoke-derived butenolide improves early growth of tomato seedlings
TLDR
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.
Butenolide from plant-derived smoke enhances germination and seedling growth of arable weed species
TLDR
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.
Effect of smoke derivatives on in vitro pollen germination and pollen tube elongation of species from different plant families.
TLDR
Results indicate that plant-derived smoke and the smoke-isolated compounds may stimulate pollen growth in a wide range of plant species.
Plant-Derived Smoke Affects Biochemical Mechanism on Plant Growth and Seed Germination
TLDR
The role of plant-derived smoke, which is changed in mineral-nutrient status, in enhancing germination and post-germination was effectively established and may help to reduce economic and human resources, which validates its candidature as a biostimulant.
Smoke-Water Enhances Germination and Seedling Growth of Four Horticultural Crops
TLDR
New evidence is provided that germination and seedling growth in non-fire-prone environments can be enhanced by plant-derived smoke, and that stimulating impacts depend on the plant species used to prepare the smoke-water.

TLDR
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.
Smoke as a germination cue: a review
TLDR
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.
A critical account on the inception of Striga seed germination.
TLDR
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.
Seed Ageing and Smoke: Partner Cuesin the Amelioration of Seed Dormancyin Selected Australian Native Species
TLDR
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.
