Germination response to winter temperatures changes with seed shape and length of temperature exposure
In many regions, the climate is changing faster during winter than during any other season, and a loss of snow cover combined with increased temperature variability can expose overwintering organisms to harmful conditions. Understanding how species respond to these changes during critical developmental times, such as seed germination, helps us assess ecological implications of winter climate change. To address this concern, we measured the breaking of seed dormancy and cold tolerance of temperate grassland species in the lab and field. In the lab, we ran germination trials testing the tolerance of 17 species to an extreme cold event. In the field, we deployed seeds of two species within a snow manipulation experiment at three locations and measured germination success biweekly from seeds subjected to ambient and reduced snow cover from winter into spring. From lab trials, cold tolerance varied among species, with seed germination decreasing <10% to 100% following extreme cold events. Cold tolerance was related to seed traits, specifically less round seeds, seeds that required cold stratification, and seeds that mature later in the season tended to be more impacted by extreme cold temperatures. This variation in seed cold tolerance may contribute to altered community composition with continued winter climate change. In the field, germination increased through late winter, coinciding with the accumulation of days where temperatures were favorable for cold stratification. Through spring, germination success decreased as warm temperatures accumulated. Collectively, species-specific seed cold tolerances and mortality rates may contribute to compositional changes in grasslands under continued winter climate change.
Elevation filters seed traits and germination strategies in the eastern Tibetan Plateau
<p><span><span><span><span><span><span><span><span><span><span><span>Seeds are the colonizing propagules for many plants and may therefore contribute to the filtering of species during the process of colonization and community assembly. Environmental filtering of seed traits may occur among species and influence community composition, or within species and influence the environmental breadth that a given species inhabits. To test for evidence of such filtering of seed traits, we measured morphological and germination traits of seeds of 408 angiosperm species collected across an elevational gradient in the eastern Tibetan Plateau grasslands. We tested for elevational filtering of traits at the species level, as well as within 22 of those species that occurred at different elevations, in order to test whether within-species variation reflected among-species patterns. Elevational patterning occurred in both seed morphology and seed germination. Seeds were smaller, more elongated, and had a higher surface area:volume ratio and shorter germination times at higher elevation. Seed morphology was associated with germination such that more elongated and smaller seeds with a higher surface area:volume ratio germinated faster, leading to earlier germination in seeds from high elevation. Within species, elevational variation in seed traits was observed in several species, but species differed in how those traits were distributed across elevation. These results suggest that taxonomic differences in seed traits may contribute to elevational variation in the species composition of plant communities, but that seed traits may be variably selected by elevation within species.</span></span></span></span></span></span></span></span></span></span></span></p>
Germination and epiphytic seed fungi on Festuca roemeri and Danthonia californica
<p>Demographic studies measure drivers of plant fecundity such as seed production and survival, but few address environmental drivers of seed viability, such as germination and dormancy. Variation in climate and seed type may both directly and indirectly alter seed germination via altered fungal pathogen abundance.</p> <p>We examined seed germination and microbial communities of seeds of <i>Danthonia californica</i>, which are either chasmogamous (external, wind-pollinated) or cleistogamous (internal, self-fertilized) and <i>Festuca roemeri</i>, which are solely chasmogamous. Seed populations were sourced across environmental gradients. We tested germination and characterized seed fungal community structure, using high-throughput sequencing.</p> <p>For <i>F. roemeri</i>, maternal plant significantly influenced germination as did climate and pathogens; germination increased in wetter, cooler sites. For <i>D. californica</i>, the main drivers of germination were maternal plant, seed type and pathogens; on average, more chasmogamous seeds germinated. Fungal composition depended on seed type, with fewer fungi associated with cleistogamous seeds. Seed fungal composition varied with climate, plant density and mean proportion of seeds germinated.</p> <p>Putative pathogens that were negatively correlated with germination were more abundant for both <i>Danthonia</i> and <i>Festuca</i> chasmogamous seeds than <i>Danthonia</i> cleistogamous seeds. In <i>D. californica</i>, cleistogamous and chasmogamous<i> </i>seeds contain vastly different fungal communities.</p>
Data from: Influential neighbours: seeds of dominant species affect the germination of common grassland species
<p><b>Questions</b></p> <p>Germination is the prerequisite of successful establishment in plant communities and is influenced by many factors. Therefore, seeds are under strong selective pressure to sense and integrate information about their environment and modulate germination based on them. In this study, we focus on interspecific seed-seed interactions under optimal and sub-optimal conditions to test three hypotheses: (H1) Dominant species' seeds and emerging seedlings are most likely to be recognized and insert significant effect on the germination of common subordinate species; (H2) Taxonomically related species are expected to exert stronger influence than un-related species on the germination of neighbouring seeds; (H3) Facilitative interactions are more likely to occur under sub-optimal conditions (drought stress) in the seed-seed interactions.</p> <p><b>Location</b></p> <p>Semi-dry temperate grassland belonging to Festuco-Brometea class, Cluj-Napoca, Romania</p> <p><b>Methods</b></p> <p>We assessed the rate and speed of germination of three common subordinate Asteraceae species (target species) in a controlled germination experiment. <span>The target species' seeds were sown in combination with low and high densities of neighbour species: two dominant Poaceae species, two subordinate Asteraceae species and two subordinate Apiaceae species; under optimal or drought conditions.</span></p> <p><b>Results</b></p> <p>Under optimal water conditions, particularly the seeds of the two dominant Poaceae species affected the germination of target species. Under drought stress, almost all neighbouring species altered the germination of two of the target species, enhancing or reducing their germination rate. Facilitation in seed-seed interactions was proved to be species-specific rather than general under drought conditions.</p> <p><b>Conclusions</b></p> <p>We found evidence that the status in a plant community (dominant or subordinate), but not the taxonomic relatedness influences the outcome of seed-seed interactions during germination. Under drought stress, the persistent competitive effect of the dominant species might considerably hinder the recruitment of subordinate grassland species.</p>
Unraveling the effects of cold stratification and temperature on the seed germination of invasive Spartina alterniflora across latitude
<p>Seed germination is critical to the life history of plants, playing an important role in the successful recruitment, colonization, and even invasion of new individuals within and outside population distribution ranges. Cold stratification and temperature are the key factors affecting seed germination traits. Studying how these two factors drive geographical variation in seed germination is essential to analyze and predict the geographical distribution range of alien plants in novel habitats. <em>Spartina alterniflora</em>, native to the United States, was introduced into China in 1979 and has spread over 20° of latitude along the eastern coast of China. Germination plays a crucial role in <em>S</em>. <em>alterniflora</em>'s large-scale invasion and diffusion across latitude. To evaluate the effects of cold stratification and temperature on seed germination of <em>S</em>. <em>alterniflora </em>across latitude, we collected seeds at seven locations across latitude in China. We exposed these provenances to cold stratification at 4°C (0, 1, 3, and 5 months) and germination temperature (5°C, 15°C, 25°C, and 35°C) treatments in growth chambers. Seed germination was observed for 98 days, and we calculated germination rate, germination index, and germination time. Results indicated that longer cold stratification significantly promoted germination rate and germination index, but decreased germination time. Similarly, higher germination temperature significantly promoted germination rate and germination index, but decreased germination time. Moreover, there were significant interactive effects on germination traits between cold stratification and temperature. Seed germination traits showed linear relationships with latitude, indicating that <em>S</em>. <em>alterniflora </em>seeds from different provenances germinated at different times and adopted different germination strategies. The stratification and temperature are the most important factors regulating the dormancy and germination seeds, so they can be important drivers of this variation along latitude. Under scenarios of warmer regional temperature, seeds at higher latitudes could germinate earlier and higher germination rate, which would favor a potential northern expansion of this invasive plant.</p>
Swida amomum seed germination
<p>Premise: Effective seed dispersal is essential in population dynamics of plant species. Swida amomum (Silky dogwood) exhibits a dispersal syndrome characteristic of autumn-ripening shrubs with fleshy fruits, where attached fruits are ingested and defecated by birds while fallen fruits are consumed by ground-foraging birds and mammals. </p> <p>Methods: We documented that fallen fruits of this shrub were consumed by two aquatic turtle species (Eastern painted turtle, Chrysemys picta and Red-eared slider, Trachemys scripta) and that their seeds were defecated. We compared germination success (percentage of seeds germinated) of defecated seeds, seeds collected from pond surface, and seeds removed from shrubs.</p> <p>Results: While four seed taxa were identified in fecal samples, seeds of S. amomum were the most frequent (93%) among samples and the most numerous (106 seeds) in any sample. Average proportion of fecal seeds germinated (85.99%) exceeded that of seeds from pond surface (82.76%) and from shrubs (60.24%), albeit the difference in germination success was insignificant. When analyzed using fecal samples from Painted turtles only, the difference in germination success between fecal seeds and those collected from pond or shrub became significant.</p> <p>Conclusions: Our findings represent the first report of S. amomum seeds being dispersed by turtle gut passage and suggest aquatic turtles could be an important part of a secondary seed dispersal process influencing woody plant community composition in temperate wetland ecosystems.</p>
Effects of warming temperatures on germination responses and trade-offs between seed traits in an alpine plant
<p>1. Climate warming may affect multiple aspects of plant life history, including important factors such as germination responses and the key trade-off between offspring size and number. As a case study to address these concepts, we used an alpine plant (waxy bluebell, <em>Wahlenbergia</em> <em>ceracea</em>; Campanulaceae) that shows plasticity to warming in seed traits and in which seed dormancy status regulates germination. We chose an alpine species because alpine environments are ecosystems particularly under threat by climate change.</p> <p>2. We conducted germination assays under cool and warm temperatures using seeds produced by individuals that were grown under historical (cooler) and future (warmer) temperature scenarios. We assessed the presence of a seed size vs number trade-off, and then examined the effects of seed number and size on germination percentage, the fractions of dormant and viable seeds, and germination velocity. Further, we examined whether warming during parental growth and during germination affected these relationships.</p> <p>3. We found evidence for a seed size vs number trade-off only under historical parental temperatures. Indeed, under future growth temperatures, parental plants produced fewer and smaller seeds and there was no evidence of a trade-off. However, the reductions in both seed traits under warming did not affect germination, despite correlations of seed size and number with germination traits. Warming increased germination, particularly of larger seeds, but overall it resulted in more than fourfold reductions in parental fitness.</p> <p>4. Synthesis. Our study shows the importance of growth conditions when evaluating the seed size vs number trade-off. Stressful conditions, such as warmer temperatures, can restrain the ability of plants to reach optimal investment in reproduction, masking the trade-off. By analysing responses across the whole life cycle, we show here an overall detrimental effect of warming, highlighting the potential risk of climate change for <em>W</em>. <em>ceracea</em>, and, potentially, for alpine plant communities more widely. </p>
Seed dormancy types and germination response of 15 plant species in temperate montane peatlands
<p>Despite their crucial role in determining the fate of seeds, the type and breaking mode of seed dormancy in peatland plants in temperate Asia with a continental monsoon climate are rarely known. Fifteen common peatland plant species were used to test their seed germination response to various dormancy-breaking treatments, including dry storage (D), gibberellin acid soaking (GA), cold stratification (CS), warm followed cold stratification (WCS), GA soaking + cold stratification (GA+CS) and GA soaking + warm followed cold stratification (GA+WCS). Germination experiment, viability and imbibition test, and morphological observation of embryos were conducted. Of the 15 species, nine showed physiological dormancy (PD), with non-deep PD being the dominant type. Four species, <em>Angelica pubescens</em>, <em>Cicuta virosa</em>, <em>Iris laevigata </em>and<em> Iris setosa</em> exhibited morphological physiological dormancy. Two species, <em>Lycopus uniflorus</em> and<em> Spiraea salicifolia</em>, demonstrated non-dormancy of seeds. Overall, the effect hierarchy of dormancy-breaking is: CS > GA > WCS > GA+CS > D > GA+WCS. Principal component analysis demonstrated that seed traits, including embryo length: seed length ratio, seed size, and monocot/eudicot divergence, are more likely to influence seed dormancy than environmental factors. Our study suggests that nearly 90% of the tested peatland plant species in the Changbai Mountains demonstrated seed dormancy, and seed traits (e.g. embryo to seed ratio and seed size) and abiotic environmental factors (e.g. pH and temperature seasonality) are related to germination behavior, suggesting seed dormancy being a common adaptation strategy for the peatland plants in the temperate montane environment.</p>
POST-FIRE-GERMINATIVE-RESPONSE,-FRUITS-AND-SEEDS-TRAITS-OF-SOME-SPECIES-OF-THE-TDF-IN-COLOMBIA
<p>In fire-prone ecosystems, certain plant species possess diaspores with morphological and physiological traits that enable them to persist and thrive following fire events. Postfire germination has been associated with various fruit and seed traits, including fruit lignification, seed size, seed weight and seed dormancy. However, the collective role and interactions of these traits in determining germination tolerance after wildfires remain unclear. We characterized ten key traits (fruit type and size (length and width), seed mass and size (length and width), dispersal mechanism, storage behavior, seed dormancy, and ecological guild) across eighteen species exhibiting three post-fire germination responses (tolerant, sensitive, and stimulated). Multinomial logistic regression was used to determine the relationship between these traits. Our findings suggest practical implications for restoration and enrichment strategies in Colombian tropical dry forests by prioritizing species with protective fruits, dormant and orthodox seeds to increase the probability of sexual regeneration after fires, and to contribute to the functional diversity and resilience of these ecosystems.</p>

Data from: Does the reduction of seed dormancy during ex situ cultivation affect the germination and establishment of plants reintroduced into the wild?
<p><span>1. Plants or seeds produced in botanic gardens or nurseries have become an important source of plant material for reintroductions or population reinforcements. However, recent research has shown that these living collections bear the risk of being genetically impoverished and adapted to the artificial habitat. In particular, many studies have reported a decline of seed dormancy during ex situ cultivation, which may compromise their suitability for reintroduction programs. However, the impact of those ex situ-derived changes on the germination and establishment of reintroduced plant populations is still unclear. </span></p> <p><span>2. We studied the germination behaviour, population establishment and plant fitness over three years of reintroduced plants of the short-lived perennial <em>Digitalis</em> <em>lutea</em>, comparing plants grown from (1) a 30-year botanic garden population, (2) seeds from a seed bank representing the initial starting point of the botanic garden culture, and (3) a re-sampled corresponding wild population. </span></p> <p><span>3. Under laboratory conditions, wild-collected seeds required cold stratification to germinate, whereas seeds from the garden population germinated without stratification. This pattern was strongly reduced in an outdoor pot experiment, where only a few garden seeds germinated before winter, and all seeds remained dormant when seeded in the natural area of origin. In a transplant experiment, reintroduced plants from the wild population outperformed both, the garden and the seed bank plants, in their fitness in the first 3 years after reintroduction suggesting adaptation to current climatic conditions. </span></p> <p><span>4. Synthesis and Applications: Our study demonstrates that trait changes that occurred during ex situ cultivation can negatively impact the establishment of reintroduced plants. We conclude that wild plant material collected from contemporary populations is best suited for reintroduction and should be preferred over ex situ-cultivated and seed bank stored material, especially when the cultivation spanned multiple generations. However, our study also shows that germination requirements change in complex ways, and the loss of dormancy observed under laboratory conditions may not always be directly transferable to natural conditions. When established standards are respected, ex situ propagated material may thus still be a valuable resource, especially when wild material is not available in sufficient quantities. </span></p>
