“…Reports on the effects of these chemicals on biometric parameters and biochemical changes occurring in plants have appeared in the literature. The examples presented in this review confirm that KARs are very promising for growth regulation in different plant species [Morffy et al 2016, Kępczyński 2020].…”

“…However, many examples exist of using these compounds in in vitro cultures. Studies have confirmed that compounds from this group greatly influence the course of in vitro organogenesis, vital processes of plant in vitro cultures, and anatomical changes in tissues [Aremu et al 2016, Kępczyński 2020. This is mainly due to the spontaneous action of KARs and their interaction with other growth regulators added to the media.…”

“…Currently, as Kępczyński [2020] pointed out, there are only a few examples of KAR1 use as elicitors increasing the biosynthesis of some secondary metabolites. Research in this aspect could contribute to the general knowledge of this little-known group of phytohormones and increase the bioreactor extraction of valuable substances used in the pharmaceutical industry.…”

Karrikins are a group of chemicals found in plant-derived smoke from burning plant material. Till now, scientists concentrated on their effect on seed germination in plants sensitive to smoke. However, there are reports on the effect of karrikins on physiology and morphology in plants which do not occur in fire areas and are not naturally treated by smoke. These chemicals positively affect the biometric parameters of the in vitro cultured plants. Recently, their effect on germination rate of pollen in several species has been confirmed. They interact with plant growth regulators enhancing their effects, for example using them together with auxins, cytokinins, gibberellins, abscisic acid or ethylene. This paper contains a review of present research on karrikins and proposes perspectives of further investigations, as well as application of these chemicals in horticultural production as a new group of plant growth regulators.

“…A number of studies have been conducted so far to reveal the mechanism of action related to plant-derived smoke water or karrikins, but the complete process is still a mystery. Several studies have revealed similarities between the action mechanisms of smoke-saturated water and karrikinolide and those of plant growth regulators associated with the growth and development of plants ( Singh et al., 2014 ; Kepczyński, 2020 ). Smoke-saturated water/karrikinolide plays a potent role in the seed germination process, similar to gibberellic acid ( Drewes et al., 1995 ; Van Staden et al., 1995 ).…”

IntroductionThe current study was carried out with the hypothesis that foliar application of plant-derived smoke water (PDSW) and karrikinolide (KAR1) might enhanced the plant growth, physiology, and essential oil production of the Mentha arvensis L. Karrikinolide (KAR1) is one of the most important bioactive constituents of PDSW. MethodsMint (Mentha arvensis L.) was grown in natural conditions in the net-house. Different concentrations of PDSW (1:125, 1:250, 1:500 and 1:1000 v/v) and KAR1 (10-9 M, 10-8 M, 10-7 M and 10-6 M) were used as foliar-spray treatments, using double-distilled water as control. The PDSW was prepared by burning the dried wheat-straw that acted as a growth-promoting substance.ResultsFoliar-spray treatment 1:500 v/v of PDSW and 10-8 M of KAR1 proved optimal for enhancing all morphological, physiological, and essential-oil yield related parameters. In comparison with the control, 1:500 v/v of PDSW and 10-8 M of KAR1 increased significantly (p ≤ 0.05) the height of mint plant (19.23% and 16.47%), fresh weight (19.30% and 17.44%), dry weight (35.36% and 24.75%), leaf area (18.22% and 17.46%), and leaf yield per plant (28.41% and 23.74%). In addition, these treatments also significantly increased the photosynthetic parameters, including chlorophyll fluorescence (12.10% and 11.41%), total chlorophyll content (25.70% and 20.77%), and total carotenoid content (29.77% and 27.18%). Likewise, 1:500 v/v of PDSW and 10-8 M of KAR1 significantly increased the essential-oil content (37.09% and 32.25%), essential oil productivity per plant (72.22% and 66.66%), menthol content (29.94% and 25.42%), menthyl acetate content (36.90% and 31.73%), and menthone content (44.38% and 37.75%). Furthermore, the TIC chromatogram of the GCMS analysis revealed the presence of 34 compounds, 12 of which showed major peak areas. DiscussionTreatment 1: 500 v/v of PDSW proved better than the treatment 10-8 M of KAR1 with regard to most of the parameters studied. The outcome of the study can be used as a recommendation tool for agricultural and horticultural crops, since it costs much lesser than that of KAR1. In fact, the foliar application of PDSW proved economical and played bioactive role at very low concentrations.

“…This information generated great interest, followed by a large number of publications on the influence of smoke and SW on seed germination in several plant species. The role of smoke in seed germination was also described in reviews [ 5 , 7 , 8 , 9 , 10 , 11 , 12 ]. It has been reported that seeds or seedlings of over 1300 plant species respond to smoke or SW [ 7 , 12 ].…”

Plant-derived smoke and smoke water (SW) can stimulate seed germination in numerous plants from fire-prone and fire-free areas, including cultivated plants and agricultural weeds. Smoke contains thousands of compounds; only several stimulants and inhibitors have been isolated from smoke. Among the six karrikins present in smoke, karrikin 1 (KAR1) seems to be key for the stimulating effect of smoke. The discovery and activity of highly diluted SW and KAR1 at extremely low concentrations (even at ca. 10−9 M) inducing seed germination of a wide array of horticultural and agricultural plants have created tremendous opportunities for the use of these factors in pre-sowing seed treatment through smoke- or KAR1-priming. This review presents examples of effects exerted by the two types of priming on seed germination and seedling emergence, growth, and development, as well as on the content of some compounds and enzyme activity. Seed biotechnology may involve both SW and KAR1. Some examples demonstrate that SW and/or KAR1 increased the efficiency of somatic embryogenesis, somatic embryo germination and conversion to plantlets. It is also possible to stimulate in vitro seed germination by SW, which allows to use in orchid propagation.
