In this study, we investigated the influence of cold stratification on seed germination in S. × niederederi, a hybrid between the North American S. canadensis and the European S. virgaurea, using fruit samples collected in 2016 in Poland. We aimed to test the hypothesis that the low temperature exposure decreases the final percentage and speed of seed germination in the hybrid and its parental species. For each species, sets of 100 achenes in three replications were mixed with dry sand and stored in Petri dishes in darkness for 12 weeks, at −18 °C and + 4 °C, and + 25 °C. The seeds were incubated for 21 d at room temperature (+25 °C), under the 12 h photoperiod (630 lx). We showed a lack of significant differences in: (i) the final percentage of germinated seeds of studied species stored at the same conditions, (ii) the final percentage of germinated seeds between the applied stratification conditions in the hybrid and its parental species, and (iii) the mean values of Timson’s index, mean germination time, and coefficient of velocity of germination between the stratification conditions in each species. The statistically significant inter-specific differences in the mean germination time parameter after the +25 °C treatment suggest that the seeds of S. × niederederi are able to germinate faster than the seeds of its parental species. However, to improve our knowledge of naturalization and invasion abilities of S. × niederederi by sexual reproduction, the seed germination and seedling survival of the hybrid should be tested in the field.

“…In light of our previous study (Bochenek et al 2004 it may be stated that it is not easy to explain the physiological mechanisms of dormancy induction and release in the achenes of M. maritima, in contrast to other perennial species, such as creeping thistle (Edwards et al 2000;Bochenek & Giełwanowska 2006;Bochenek et al 2009). Scentless mayweed achenes exhibit non-deep physiological dormancy, which is typical of most weeds in the Asteraceae family, and can be released by after-ripening in dry storage and warm or cold stratification (Baskin & Baskin 2004;Finch-Savage & Leubner-Metzger 2006).…”

Matricaria maritima ssp. inodora is a species with varied life cycles. To investigate the ecophysiology of seed dormancy and germination in this species, we examined the effect of stratification temperature, after-ripening, as well as daily temperature fluctuations. The results were summarized in terms of the hydrotime model for germination. The process of dormancy release took place mainly during wet storage and proceeded much faster at lower temperatures than at higher temperatures. Dry storage did not play an important role in dormancy regulation. Alternating temperatures with an amplitude of 14°C decreased seed germination mainly by increasing their sensitivity to water stress. The hydrotime model allowed a better understanding of the physiological basis of dormancy development and relief.

“…Bochenek et al [46] reported differences between the cultivars of Brassica napus L. seed in their potential to exhibit secondary dormancy following environmental stress. A significant number of differences in gene expression between the cultivars were apparent in the transition from full-size embryo to mature seed.…”

“…Breaking primary dormancy of achenes in Cirsium arvense only took place during the first stratification month at moderate temperature, which is mainly due to an increase in the average water stress tolerance in seed population. The induction of secondary seed dormancy during after-ripening at all temperature resulted mostly from a substantial loss of the seed's ability to tolerate water stress [46].…”

Seed Dormancy and Germination

View full text Add to dashboard Cite

This chapter deals with seed dormancy of agricultural weeds, its definitions and types from the physiological and ecological point of view, and physiological and ecological factors inducing dormancy in different weed species. The role of different environmental factors, agricultural practices including herbicides application, selection pressure, and seasonal dormancy, weed density and population regulation, seed phenology, polymorphism, and modifications were emphasized. Factors induce or terminate dormancy and enhance seed germination and dormancy breaking have been mentioned and evaluated in addition to the ecological importance of seed dormancy and herbicide resistance, genetic bases of dormancy, and molecular studies were presented. The role of allelochemicals, stresses, and dormancy and their effects on seed longevity and germination regulation were thoroughly discussed. Dormancy breaking under laboratory conditions, role of plant hormones and other chemicals, and dormancy management in the field were reviewed in addition to information on seed dormancy/longevity and germination stimulants. Seed germination stimulants and inhibitors of parasitic weed and seed dormancy as a weed survival strategy were presented and discussed.
