“…The cultivation of seeds from common gardens may also lead to new adaptations of the plants to the common garden environment (Münzbergová et al, 2019). To disentangle direct environmental responses and maternal effects, studies that explicitly compare patterns and responses between field‐collected and garden‐cultivated seeds are needed (see Horovitz et al, 1975; Rojas‐Arechiga et al, 2001; Liu and Han, 2008; Schroder and Prasse, 2013; De Vitis et al, 2014).…”

Despite the existence of many studies on the responses of plant species to climate change, there is a knowledge gap on how specific climatic factors and their interactions regulate seed germination in alpine species. This understanding is complicated by the interplay between responses of seeds to the environment experienced during germination, the environment experienced by the maternal plant during seed development and genetic adaptations of the maternal plant to its environment of origin. METHODS:The study species (Anthoxanthum alpinum, A. odoratum) originated from localities with factorial combinations of temperature and precipitation. Seed germination was tested in conditions simulating the extreme ends of the current field conditions and a climate change scenario. We compared the performance of field-collected seeds with that of garden-collected seeds. RESULTS:A change to warmer and wetter conditions resulted in the highest germination of A. alpinum, while A. odoratum germinated the most in colder temperature and with home moisture. The maternal environment did have an impact on plant performance of the study species. Field-collected seeds of A. alpinum tolerated warmer conditions better than those from the experimental garden. CONCLUSIONS:The results demonstrate how knowledge of responses to climate change can increase our ability to understand and predict the fate of alpine species. Studies that aim to understand the germination requirements of seeds under future climates should use experimental designs allowing the separation of genetic differentiation, plasticity and maternal effects and their interactions, since all these mechanisms play an important role in driving species' germination patterns.

“…MPD is found in eight of the 37 families. MPD has been investigated in the Apiaceae (Baskin and Baskin, 1998), Caprifoliaceae (Hidayati et al , 2000a, b, c), Fumariaceae (Baskin and Baskin, 1994; Kondo et al , 2005), Iridaceae (Morgan, 1990; Shipley and Parent, 1991; Coops and van der Velde, 1995), Menyanthaceae (Hewett, 1964; Baskin et al , unpublished), Papaveraceae (Baskin and Baskin, 1984; Baskin et al , 2002; Karlsson et al , 2003), Ranunculaceae (Horovitz et al , 1975; Forbis and Diggle, 2001) and Sarraceniaceae (Ellison, 2001). Further, seeds of Ribes ( Grossulariaceae ) have an underdeveloped embryo and are highly dormant (Young and Young, 1992), but MPD in this genus has not been studied in detail.…”

2007). A revision of Martin's seed classication system, with particular reference to his dwarf-seed type. AbstractMartin's (1946) seed classification system has 10 types based on embryo and endosperm characteristics and two additional types based on seed size: dwarf (0.3-2.0 mm) and micro (#0.2 mm). He listed 17 families and 12 genera (in five other families) as having dwarf seeds. Our recent discovery of morphophysiological dormancy in dwarf seeds of several taxa of Campanulaceae and one of Gentianaceae prompted an evaluation of dwarf seeds. Martin's paper contains 37 families with one to several small (0.3-2.0 mm) seeded species that he did not list as being dwarf. Comparison of Martin's dwarf families and the 37 small-seeded non-dwarf families revealed no consistent differences between the two groups in endosperm texture, seed-coat anatomy, embryo morphology, class of seed dormancy or phylogenetic position. Also, Martin's dwarf seeds include a variety of embryo morphologies. Consequently, we have revised Martin's key to seed types. The dwarf category has been removed and the micro category replaced by 'undifferentiated' to reflect the state of the embryo in fresh seeds. Further, the key now includes linear fully developed, linear underdeveloped, spatulate fully developed and spatulate underdeveloped seed types, which Martin illustrated but did not include in his key. In the revised key, all seeds are distinguished on the basis of embryo and endosperm characteristics.

“…In some species, cultivated and wild forms differ with respect to morphophysiological dormancy. For example, in Anemone coronaria L, cultivated 'de Caen seeds showed only morphological dormancy (requiring only warm treatment), while wild populations of Anemone displayed morphophysiological dormancy and required warm followed by cold stratification (Horovitz et al, 1975).…”
