“…The action of SW has been paralleled to that of gibberellic acid (GA 3 ) [40,41]. Butenolide could act in a similar fashion as GA 3 and stimulate seed germination of light-sensitive species (Angianthus tomentosus, Myriocephalus guerinae and Podolepis canescens), providing evidence that butenolide can promote seed germination of light-sensitive seeds [42].…”

Plant-derived smoke water (SW), derived from combusted plant material, has been shown to stimulate seed germination and improve seedling vigor of a number of plant species from fire-dependent Mediterranean-type climate areas. The effects of SW on seed germination of 13 plant species from southern tropical and subtropical monsoon climate regions of South China are reported for the first time in this study using laboratory and pot trials. Among the 13 species tested, only Aristolochia debilis showed a significant positive response to commercial SW when diluted 1:10. Seed germination of A. debilis was also stimulated by 1-100 nM 3-methyl-2H-furo [2, 3-c] pyran-2-one (karrikin 1 or KAR 1 ) and by 10-1000 µM gibberellic acid (GA 3 ). GA 3 stimulated seed germination of Santalum album and significantly elongated the radicles of A. debilis while SW could not. The functions and/or metabolic pathways of Kar 1 and GA 3 are likely to be separate and/or distinct.

“…In addition, there is a large group of plant, fungal, and algal chemicals that promote or inhibit general plant or root growth. Putative plant regulators range from polypeptides, such as systemin, to polysaccharides, and to undefined volatile compounds in smoke from burning vegetation [Drewes et al, 1995]. Plant physiologists are therefore justified in feeling a level of skepticism towards proposed novel regulatory molecules involved in plant growth and development.…”

Putative regulatory molecules in plants: evaluating melatonin

Numerous classes of chemicals have been considered as regulators of various aspects of plant growth and development. In evaluating these putative regulatory molecules, plant biologists have encountered a number of challenges, including: the problem of quantifying substances present at trace levels in extremely complex mixtures; difficulty in obtaining and interpreting phenotypic responses to exogenous applications; and, until recently, the inability to selectively alter endogenous levels of these substances. Melatonin (N-acetyl 5-methoxytryptamine), a methoxylated indoleamine, is a potential regulatory molecule found in plants. Although no specific phenotype is currently associated with melatonin or its analogs in higher plants, it has important and unique biological activity in many other taxa, from algae to primates. In these organisms, melatonin functions as a night signal, coordinating responses to diurnal and photoperiodic environmental cues. We assess the process by which melatonin has been evaluated in plants so far and find that many of the methods for melatonin analysis, which have been adopted from animal studies, are inappropriate for use with plant materials. Thus, despite some interesting preliminary reports, research supporting the case for melatonin as a plant regulator is still in its infancy.

“…It can be assumed that SGV influences the dynamic hormonal and redox balance in seeds whose dormancy is broken by low temperature or light [37,39,40]. Considering an invasive species, Solidago gigantea, further research on the impact of SGV on other invasive plants in Europe would be worthy to be carried out, because unlimited possibility of shopping and travelling, together with the climatic changes largely contribute to ecological invasions [41,42].…”

Swailing affects seed germination of plants of European bio-and agricenosis in a different way

Swailing as a part of agricultural practice is an illegal habit in many European countries. The indirect effect of swailing is the emission of volatiles (SGV), hence the aim of the study was to identify their impact to seeds of different species occurring or grown Europe. It was carried out on seeds of 29 species of 10 botanical families within the angiosperms. The response to SGV was more or less differentiated within a family, and even within the species, e.g. in the case of tomato. The stimulation of germination and/or increased seedling vigour was established in celery, green- and red-leafed basil, white and red cabbage, white clover and wild thyme. The same effect was noticed for the seeds of stratified broadleaf plantain and the positively photoblastic seeds of German chamomile germinated in darkness. The inhibition of seed germination and/ or reduced seedling vigour was demonstrated in case of caraway, dill and forget-me-not. Similar results were obtained in the experiments carried out in vitro and in the soil, hence it can be assumed that the indirect impact of SGV on plant habitat composition is likely. The interaction of SGV compounds with seed testa and seed phytohormones is discussed.
