Smoke, smoke‐water and aerosols have a stimulatory effect on seed germination and growth vigour of many seedlings, making them potentially useful for different purposes, provided they do not pose a health risk. Therefore, the genotoxicity of two kinds of smoke‐water and 3,7‐dimethyl‐2H‐furo[2,3‐c]pyran‐2‐one, a variant of the most active smoke compound (3‐methyl‐2H‐furo[2,3‐c]pyran‐2‐one) was evaluated using the Vitotox™ assay. Smoke‐water extracts were obtained from burning leaves: Themeda… Expand
Genotoxicity testing of 3,4,5-trimethylfuran-2(5H)-one, a compound from plant-derived smoke with germination inhibitory activity.
TLDR
A genotoxicity study of 3,4,5-trimethylfuran-2(5H)-one, a compound from plant-derived smoke previously shown to have germination inhibitory activity, results support a previous study where a related smoke-derived compound with germination promoting properties was investigated. Expand
Genotoxicity studies on plant growth promoting smoke-water and smoke-derived compounds using Vicia faba and Persea americana S10 metabolic activation
TLDR
Findings confirmed previous findings that the use of ‘smoke technology’ can, at least according to the results of this genotoxicity evaluation, be regarded as being safe for use in agriculture, horticulture and other related sectors. Expand
Smoke-saturated Water and Karrikinolide Modulate Germination, Growth, Photosynthesis and Nutritional Values of Carrot (Daucus carota L.)
TLDR
This study provides an insight into an affordable and feasible method of crop improvement by investigating the efficacy of smoke-saturated water (SSW) and KAR1 on carrot. Expand
Growth stimulation effects of smoke-water and vermicompost leachate on greenhouse grown-tissue-cultured ‘Williams’ bananas
TLDR
Soil drenching with smoke-water significantly increased the root length as well as fresh and dry weight when compared to foliar application and the positive effect on rooting is beneficial for acclimatization and establishment of tissue-cultured banana plantlets in nurseries and subsequent transfer to the field. Expand
Interactions between a plant growth-promoting rhizobacterium and smoke-derived compounds and their effect on okra growth
TLDR
Investigating the interactions between Bacillus licheniformis and two concentrations each of smoke–water, KAR1, and TMB on okra showed that all treatments had no significant effect on the rhizosphere microbial abundance, and the modes of interaction between PGPR and smoke-derived compounds need to be further elucidated. Expand
Afritoxinones A and B, dihydrofuropyran-2-ones produced by Diplodia africana the causal agent of branch dieback on Juniperus phoenicea.
TLDR
This study represents the first report of secondary metabolites produced by D. africana, a fungal pathogen responsible for branch dieback of Phoenicean juniper in Italy, and the taxonomic implications ofsecondary metabolites in Botryosphaeriaceae family studies are discussed. Expand
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. Expand
Chemical and biological characterization of phytotoxins produced by Diplodia species, fungi involved in forest plants diseases
TLDR
The fungi and the phytotoxins associated with canker disease of the Italian cypress and the branch dieback of juniper which are plant diseases with noteworthy social and economical implications are studied. Expand

TLDR
In all tests performed, no mutagenic activity was induced by 3-methyl-2H-furo[2,3-c]pyran-2-one, with or without S9 metabolic activation, and it is of importance that no toxic and genotoxic effects were observed at the concentrations tested. Expand
