“…Desta forma, entender o comportamento germinativo da semente é importante para compreender a ocupação de uma espécie em determinados ambientes, e de acordo com Melo et al (2018), a rápida germinação é característica predominante em espécies estrategistas, pois estas aproveitam as condições favoráveis para a sua germinação e desenvolvimento, no entanto, para a chicória da Amazônia, observa-se que a mesma não apresenta o comportamento de espécie estrategista, visto que há uma lenta germinação.…”

“…Tendo em vista que o processo de germinação é uma fase de considerável importância no ciclo de vida do vegetal, caracterizado pela embebição de água pelas sementes, um dos fatores que mais influencia no processo de germinação das sementes é a disponibilidade de água. Pois, através da absorção de água ocorre a reidratação dos tecidos, a natural intensificação da respiração e das demais atividades metabólicas, que resultam no fornecimento de energia e de nutrientes necessários para o desenvolvimento do eixo embrionário, além de contribuir para o aumento da porcentagem de germinação NAKAGAWA, 2012;ARAÚJO et al, 2018;SOUZA et al, 2018).…”

Manilkara zapota L., popularly known as sapoti, has commercial relevance both for fruits, with high prices in the regional markets, and for its wood. Thus, the propagation of this species can be done by seed, however, the germination is slow and uneven. The objective of this work was to study the biometry of the seeds and to evaluate pre-germinative treatments to facilitate the propagation of sapoti. The fruits were from the municipality of Brejão-PE and length, width and thickness were determined in millimeters of each seed and submitted to different pre-germination treatments. The seeds were exposed to the following evaluations: biometry, dormancy overrun, germination tests, germination speed index, root length and aerial part of the seedlings and dry mass of the root and shoot of the seedlings. They have variability regarding their biometry and do not require the adoption of treatments for the breakdown of dormancy, which enables and accelerates the production of seedlings. The treatments aimed at overcoming dormancy of sapoti were not efficient to accelerate the germination of the seeds.

“…Despite the diversity of Brazilian species, few are included in the Brazilian Rules for Seed Analysis (Melo et al, 2018), and for Baccharis seeds, the criteria for the germination test are not yet established. A recommendation from the International Seed Testing Association (ISTA) for the development of standard analysis which considers the use of descriptive statistical techniques but does not restrict the proposition of new procedures (ISTA, 2008;Santana et al, 2016).…”

Baccharis trimera (Less.) DC (E1) and Baccharis crispa Spreng. (E2) possess potential antimicrobial and anti-inflammatory properties. Qualitative and quantitative information on seed germination on these species is scarce. The objective of this investigation was to establish a protocol for evaluating seed germination of E1 and E2 and to analice the scoring and curve fitting by the Germinator package, for different periods of germination were between 0.93 and 0.99. Both species showed differences in germinability and mean germination time, 27 days for E1 and 20 days for E2. The germination dispersion showed that E1 germination was homogeneous, with differences in growth pattern, whereas the results on germination of E2. The mean speed of germination determined with the experimental data was close to the values obtained by the Germinator package, with a maximum germination of more than 34%, proving that the software was efficient for evaluating germination.
