“…To accurately confirm this reasoning, we stratified the seeds. Stratification is an effective strategy for breaking dormancy by placing seeds in conditions that are similar to those of their natural habitats [43][44][45][46]. Some species with physiological dormancy can germinate at the highest percentage after warm or cold stratification [47].…”

Euphorbia maculata L. has been confirmed to have functional properties, including anticytotoxic, anti-inflammatory, and antioxidative effects. However, studies on the dormancy and germination of its seeds for cultivation purposes are lacking. The potential of E. maculata as a valuable plant species has not been fully realized due to the lack of understanding of its seed dormancy and germination characteristics. E. maculata seeds were collected and germination tests were performed at various temperatures to determine their dormant state. Next, seeds were stratified with various temperatures, and treated temperature conditions similar to those of its natural habitat to induce dormancy release. The seeds exhibited very low germination below 30 °C, which indicates the possibility of innate dormancy. Subsequently, dormancy was released by cold stratification, and an expansion in the temperature range suitable for germination was observed, confirming that E. maculata seeds exhibit conditional dormancy. Conversely, high-temperature moist stratification did not effectively break dormancy as it led to seed decay. Therefore, we treated the seeds at various high temperatures in a dry environment. This facilitated dormancy release without the need for moist stratification, allowing for seed storage while ensuring the uniform and rapid production of E. maculata seedlings and minimizing seed wastage. Additionally, seeds with broken dormancy did not require a high temperature for germination, making them more cost-effective. Therefore, comprehensively examining germination and dormancy characteristics may optimize the cultivation process of this valuable plant species, E. maculata.

“…Rout et al, 2009;Aguado et al, 2011;Gandy et al, 2015). Also, treatment with GA 3 may promote germination by increasing the growth potential of the embryo (Afolayan et al, 1997;Dissanayake et al, 2010;Duarte et al, 2012;Aiello et al, 2017;Guo et al, 2021). Scarifiction followed by treatment with GA 3 of the perennials Helianthus angustifolia, H. glaucophyllus and H. pumilus promoted cypsela germination (Castillo-Lorenzo et al, 2019).…”

The Asteraceae with up to 30,000 species occurs on all continents except Antarctica and in all major vegetation zones on earth. Our primary aim was to consider cypselae dormancy-break and germination of Asteraceae in relation to ecology, vegetation zones and evolution. Cypselae are desiccation-tolerant and in various tribes, genera, species and life forms of Asteraceae are either non-dormant (ND) or have non-deep physiological dormancy (PD) at maturity. All six types of non-deep PD are found among the Asteraceae, and dormancy is broken by cold or warm stratification or by afterripening. Soil cypselae banks may be formed but mostly are short-lived. Much within-species variation in dormancy-break and germination has been found. Using data compiled for 1192 species in 373 genera and 35 tribes of Asteraceae, we considered ND and PD in relation to life form, vegetation zone and tribe. Senecioneae and Astereae had the best representation across the vegetation zones on earth. In evergreen and semi-evergreen rainforests, more species have ND than PD, but in all other vegetation zones, except alpine/high-latitude tundra (where ND and PD are equal), more species have PD than ND. Tribes in the basal and central grades and those in the Heliantheae Alliance have both ND and PD. The high diversity and lability of non-deep PD may have enhanced the rate of species diversification by promoting the survival of new species and/or species in new habitats that became available following globally disruptive events since the origin of the Asteraceae in the Late Cretaceous.
