“…These results are consistent with previous findings (Bossuyt et al 2002;Zobel et al 2007;Plue et al 2010b;Small and McCarthy 2010;Plue et al 2010a;) and support the view that forest stand age significantly influences the diversity of the soil seed bank and its species composition. The similarities in aboveground vegetation and seed bank composition in forest stands are generally expected to be low and strongly influenced by light conditions (Hopfensperger 2007).…”

The chemical composition and mechanical attributes of soil directly influence the environment in the soil seed bank, and both of these properties change with the age of the forest stand. This study, which addresses the impact of soil properties and stand age on the structure of the soil seed bank, was conducted in the forest district of Valtice in the southern Czech Republic. The soil seed bank was sampled across different ages of forest stands. The soil properties were measured for each sample, and a seed separation method was used. A total of 14,340 seeds from 94 species were found. Three species, Urtica dioica, Circaea lutetiana and Moehringia trinervia, dominated the soil seed bank, accounting for 62 % of the total seeds. Four variables influenced the composition of the soil seed bank: soil porosity, volumetric moisture content, forest stand age and total cover of trees. Seed density and species richness in the soil seed bank decreased with increasing age of the forest stand. The results show that the soil seed bank is much more strongly influenced by forest age and total cover of the tree layer than by the tested soil properties.

“…Compositional diversity in the seed bank diminished with increasing stand age, possibly due to a gradual loss of species from the seed bank and limited input from late seral vegetation (Plue et al 2010). Decreased light availability due to tree growth and consequent canopy closure may discourage germination and seed replenishment from light-dependent variable early seral paddy plants in the seed bank.…”

Background: We sought to understand the relationship between the seed bank and vegetation in abandoned rice paddies in South Korea, in order to guide management of these sites. We investigated the floristic composition and species richness of the soil seed bank and ground vegetation in former paddies along three seral gradients (wet meadow, young forest, and mature forest) in Gwangneung Forest Biosphere Reserve. Results: Seed bank samples contained 59 species, of which the dominant families were Cyperaceae, Gramineae, and Polygonaceae. Species richness and seedling density (59 taxa and 19,121 germinants from all samples) were high. Carex spp. (11, 921 germinants) were the dominant taxa. The species composition in the seed bank changed gradually as the land transitioned from wet meadow to mature forest. Sørensen's index of similarity between above-and below-ground vegetation was 29.3% for wet meadow, 10.8% for young forest, and 2.1% for mature forest. Germinant density also declined, with 10, 256 germinants for wet meadow, 6445 germinants for young forest, and 2420 germinants for mature forest. Conclusions: Changes in aboveground environment and life history traits such as amphicarpic plants, likely affect the composition of soil seed bank species. Abandoned paddy fields may be good sites for restoration of wetland forest and conservation of wetland habitat. Some intervention may be required to promote the recovery of a natural species assemblage.

“…However, it was found that seeds kept under light provided by LED lamps had their germination potential reduced, indicating that the effect of light on seed germination is variable in many species, and these responses depend strolngly on the quality of light (Demotes-Mainard et al, 2016;Plue et al, 2010). In this context, the negative effect of LED on the germination of G. americana seeds shows a possible adaptation of the species to understory environments, since species adapted to these conditions have higher germination rates in environments with low energy levels and plenty of far-red light (Liu et al, 2012;Plue et al, 2010).…”

Therefore, the high level of energy provided by LED (peak at 460 nm, referring to blue light with a high energy level; Figure 1), associated with a higher intensity of red light, reduced germination performance of G. americana seeds.…”

“…However, for most species, speed, uniformity and germination rate depend on factors which are external and internal to the seeds. Internal factors are commonly associated with the presence of inhibitors or germination promoters, whereas external factors are related to ecophysiological characteristics of each species (Demotes-Mainard et al, 2016;Plue et al, 2010).…”

The in vitro seed germination is an effective alternative for quickly obtaining explants with sanitary quality. However, jenipapo seeds present slow and uneven germination. Therefore, internal and external factors to seed which directly interfere in the process, they must be identified, in order to adapt better techniques to obtain seedlings. In this sense, this work aimed to optimize the in vitro germination of Genipa americana L. seeds by evaluating different factors (light quality, GA 3 treatment, pre-soaking in distilled water, growing media and stratification in the dark). It was found that the seed germination of G. americana was indifferent to light, however, the best results were obtained under conditions of continuous darkness; There was no effect of the application of exogenous GA 3 ; The pre-soaking in distilled water for 48 h contributes to obtaining better germination rates; And the reduction in MS medium salts, and laminating the pretreatment in the dark maximizes the germination potential of seeds.Therefore, the optimal conditions for in vitro germination of G. americana L. seeds requires pre-soaking in distilled water for 48 hours and inoculation into culture media consisting of ½ MS + 15 g L -1 sucrose, with stratification in the dark for 16 days, followed by the transfer to growth chambers with lighting provided by white fluorescent lamps.Index terms: Genipa americana L.; in vitro culture; ligth quality; Rubiaceae; stratification in the dark. RESUMOA germinação in vitro de sementes é uma alternativa eficaz para obtenção de explantes com rapidez e qualidade sanitária. No entanto, sementes de jenipapeiro apresentam germinação lenta e desuniforme. Para tanto, fatores internos e externos às sementes que interferem diretamente no processo, devem ser identificados, visando à adaptação de melhores técnicas para obtenção de mudas. Neste sentido, objetivou-se otimizar a germinação in vitro de sementes de Genipa americana L. por meio da avaliação de diferentes fatores (qualidade de luz, tratamento com GA 3 , pré-embebição em água destilada, diferentes composições no meio de cultivo e estratificação no escuro). Verificou-se que a germinação das sementes foi indiferente a luz, no entanto, os melhores resultadados foram obtidos sob condições de escuro contínuo; Não houve efeito da aplicação de GA 3 exógeno; A pré-embebição em água destilada durante 48h contribui para obtenção de melhores taxas de germinação; E a redução de sais do meio MS, bem como o pré-tratamento de estratificação no escuro maximizam o potencial germinativo das sementes. Portanto, as condições ótimas para germinação in vitro de sementes de G. americana L. requer a pré-embebição em água destilada por 48 horas e a inoculação em meio de cultivo constituído de ½ MS + 15 g L-1 de sacarose, com estratificação no escuro por 16 dias, seguida pela transferência a salas de crescimento com iluminação fornecida por lâmpadas fluorescentes branca.Termos para indexação: Genipa americana L.; cultivo in vitro; qualidade de luz; Rubiaceae; estratif...
