“…Zhou et al [19] reported that butenolide enhanced the expression of two GAs biosynthesis genes (GA3ox1 and GA3ox2) during seed imbibition. Furthermore, Meng et al [34] demonstrated that karrikins delayed soybean seed germination through enhancing ABA biosynthesis, while impairing GAs biogenesis.…”

In this article, the effects of cold on the development of Lupine angustifolius and the possibility of mitigating it, via seed hydropriming or pre-treatment with butenolide (10−6 M–10−4 M), are investigated in two cultivars, differing in their ability to germinate at low temperature. Physiological background of plant development after cold stress was investigated in imbibed seeds. For the first four weeks, the seedlings grew at 7 °C or 13 °C. Seeds well germinating at 7 °C demonstrated higher activity of α-amylase and higher levels of gibberellins, IAA and kinetin. Germination ability at low temperature correlated with dehydrogenase activity and membrane permeability. Seed pre-treatment improved germination at low temperature by decreasing abscisic acid content. Seed hydropriming alleviated cold effects on plant development rate and yield, while butenolide accelerated vegetative development but delayed the generative phase. Potential seed yield may be predicted based on the seed germination vigour and the photosynthetic efficiency measured before flowering.

“…Despite some differences in the number of germinated seeds in both experiments, the SGV treatment was effective in terms of stimulation or inhibition also when the seeds were covered by a soil layer (Figure 7). Although the variance within a seed lot acid, IAA), or gibberellins [33][34][35][36]. The growth responses of hypocotyls or radicles grown from SGV-treated seeds also suggest the involvement of gibberellins [35].…”

Keeping in mind all the information gathered, the inhibitory effect of SGV has to be explained, too.…”

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.

“…These include the arable weeds Brassica tournefortii and Sisymbrium orientale (Brassicacaeae) (Stevens et al 2007), and Avena fatua and Sorghum halepense (Poaceae) (Daws et al 2007). A recent study of the effects of smokewater and KAR 1 on seed germination of 13 species from South China identified only one (Aristolochia debilis; Aristolochiaceae) as responding positively to 1 nM KAR 1 or more (Zhou et al 2014). However, classifying a species in a binary fashion as karrikinresponsive or karrikin-non-responsive is fraught with difficulties, because environmental factors (e.g.…”

Abstract. Karrikins are a family of compounds generated via the incomplete combustion of plant matter. Since their discovery as seed germination stimulants in 2004, a great deal has been learned about the chemistry and the biological mode of action of karrikins. Much interest and progress have stemmed from the structural similarity of karrikins to that of strigolactones -the shoot branching hormone. This review will provide a historical account of some of the more significant discoveries in this area of plant biology. It will discuss how the study of these abiotic signalling molecules, combined with advances in our understanding of strigolactones, has led us towards the discovery of new mechanisms that regulate plant growth and development.
