Abstract: Gallesia integrifolia (Spreng.) Harms, conhecida como pau-d’alho, ocorre em diversos estados brasileiros e pouco se sabe sobre a germinação de suas sementes. Assim, este trabalho objetivou avaliar a emergência de plântulas desta espécie em função do armazenamento das sementes e de diferentes substratos para a semeadura. Foram testados cinco períodos de armazenamento (45, 60, 90, 120 e 365 dias), quatro condições de armazenamento (sacos plásticos e de papel kraft colocados em temperatura e umidade ambiente e câ… Show more

“…Proper seedling production requires uniform establishment and development in terms of seedling size, and seed quality is critical to ensure this uniformity. On the other hand, it is important to understand the germination stages associated with the substrates, as the water retention capacity of the substrate together with the morphological characteristics of the seeds, can influence the percentage of germinated seeds (Silva et al, 2023).…”

“…Seed germination and seedling emergence are strongly influenced by a type of dormancy, in addition to the type of sowing substrates, which are crucial for seedling quality (Han et al, 2018, Sousa et al, 2023. Among the numerous elements that affect seedling production, substrate composition not only influences seed germination but also plays a crucial role in seedling support and development by providing nutrients, water and oxygen (Silva et al, 2023) and promoting higher photosynthetic efficiency (Afonso et al, 2020). The choice of substrate must be adapted to the specific needs of the seed in terms of its size and shape.…”
