“…Moreover, non-resource factors like temperature and daylength during seed development affect dormancy and subsequent germination (Roach & Wulff, 1987). They also act after harvest resulting in an effect of storage conditions on dormancy (Baskin & Baskin, 1998;Gutterman, 1992). Finally, processing (harvest, cleaning techniques) of seeds by seed companies (quality assurance) constitute an additional source of non-genetic variation compared to manual collection.…”

“…Differences among provenances, particularly in germination, can be inflated by heterogeneous environmental conditions among sites at which seeds were collected (environmental maternal effects: Gutterman, 1992;Lopez, Potts, Vaillancourt, & Apiolaza, 2003;Pico, Ouborg, & van Groenendael, 2003;Roach & Wulff, 1987). In order to evaluate the importance of non-genetic effects, we (a) used seed mass (known to be largely affected by the maternal environment) as a covariate in the analysis of a subset of seeds, and we (b) repeated germination experiments with one of the species (Legousia speculum-veneris) using F1 seeds produced under homogeneous conditions.…”

SummaryThe use of local seed provenances is often recommended in restoration and habitat creation because they are thought to be better adapted to local habitat conditions. However, spatial scales and the degree of population differentiation are not well known and germination is often not included in comparisons between provenances. We analysed germination as a key trait of plant development in five provenances of four species used for ecological restoration on arable land (wildflower strips). Germination was tested under different conditions in growth chambers (early vs. late spring) and in the field (non-competition vs. competition). We also examined the contribution of non-genetic (maternal) effects to population differentiation.Large differences in germination traits were found between the provenances in growth chambers and in the field. The ranking was species-specific, but largely consistent across all tested environments. Local provenances did not generally exhibit higher germination percentages in the field relative to non-local provenances. Due to the high stability of germination traits across various environments, growth chamber tests provided a reliable prediction for provenance differences in the field. The differences among provenances seemed to be largely genetically determined as the inclusion of seed mass in the analysis to control for maternal effects did not decrease the degree differences between-provenance differences. In one species, however, non-genetic contributions to population differentiation were found by comparing F1 seeds grown under homogeneous conditions and original seed material. We conclude that potentially large between-provenance differences in germination traits need to be considered in ecological restoration projects,

“…Existen evidencias que indican que efectos maternos, como la posición de la semilla en el fruto y del fruto en el árbol, la edad del árbol madre, y el tamaño de la semilla influyen en la germinación de la semilla (Gutterman 2000). Como las semillas fueron recolectadas en bosques naturales de la especie, es de esperar que los árboles madres no fueran de la misma edad.…”

“…Nevertheless, seed dormancy, maturity, tolerance to desiccation and age are intrinsically important (Bewley and Black, 1994;Daws et al, 2004). Requirements for germination are species-specific, but these requirements may also vary between and within populations from which seeds are selected for laboratory studies (Gutterman, 2000).…”

In this descriptive paper, we described germination responses of Styrax pohlii, S. camporum and S. ferrugineus seeds at 5, 10, 15, 20, 25, 30, 35, 40 and 45 °C. We also assessed the percentage germination (%G) of S. pohlii seeds with different seed water contents because, as a forest species, it seems to have recalcitrant seed behavior. Intrigued by the capacity of seeds of this species to germinate directly from puddles formed on poorly drained soils of riparian forests, where it typically occurs, we also tested the effect of de-pulping fruits on germination of S. pohlii seeds under hypoxia and normoxia conditions. In addition, we checked whether distinct concentrations of gibberellic acid (GA 3 ) could break S. ferrugineus seed dormancy, a typical seed behavior of Cerrado species. No germination occurred at 5, 40 and 45 °C, regardless of the species. The optimal temperature for germination was 20 °C for S. pohlii and 25 °C for S. camporum. However, S. ferrugineus seeds showed a very low %G, regardless of the temperature, and GA 3 could not consistently break possible physiological seed dormancy. For S. pohlii seeds, the higher the seed desiccation the lower the %G, and fruit pulp removal showed to be essential for seed germination. S. pohlii seeds germinated independently of oxygenation conditions. Key words: hypoxia, Styrax pohlii, S. camporum, S. ferrugineus, temperature, desiccation seed tolerance.Desempenho germinativo de sementes de espécies de Styrax ajuda a entender sua distribuição em áreas de Cerrado no Brasil ResumoNeste trabalho descritivo foi mostrada a resposta germinativa das sementes de Styrax pohlii, S. camporum e S. ferrugineus a 5, 10, 15, 20, 25, 30, 35, 40 e 45 °C. Avaliou-se também a porcentagem de germinação (%G) de sementes de S. pohlii com diferentes conteúdos de água, pois, por ser uma espécie florestal, suas sementes parecem ser recalcitrantes. Dada a capacidade de as sementes dessa espécie germinarem diretamente em poças d'água formadas em solos mal drenados nas florestas ripárias, onde a espécie tipicamente ocorre, também testou-se o efeito do despolpamento dos frutos para a germinação de sementes de S. pohlii em condições de hipóxia e normóxia. Além disso, verificou-se se diferentes concentrações de ácido giberélico (GA 3 ) poderiam quebrar a dormência das sementes de S. ferrugineus, que é característica de sementes de espécies do Cerrado. Não houve germinação a 5, 40 e 45 °C, independente da espécie. A temperatura ótima para a germinação foi 20 °C para S. pohlii e 25 °C para S. camporum. Porém, as sementes de S. ferrugineus mostraram %G muito baixa, independente da temperatura, e o GA 3 não quebrou consistentemente a possível dormência fisiológica dessas sementes. Para as sementes de S. pohlii, quanto maior a dessecação, menor %G, e a remoção da polpa dos frutos mostrou ser essencial para a germinação das sementes. As sementes de S. pohlii germinaram independentemente das condições de oxigenação.Palavras-chave: hipóxia, Styrax pohlii, S. camporum, S. ferrugineus, temperat...
