Resumo: The objective of the present work was to evaluate the influence of temperature and seed size on the germination of Plinia peruviana. Seeds were classified into three sizes: small (diameter ≤ 0.6 cm), average (0.6 - 1.0 cm) and large (≥ 1.5 cm). They were sown in plastic boxes containing vermiculite and Plantimax® (1:1) as substrate. The boxes were distributed in two temperature conditions: environmental temperature (22 ºC ± 2) and germination chamber (30 ºC ± 2). The experiment was conducted in a completely randomized design. After 45 days, germination (%), germination speed index (GSI), mean germination time (MGT), mean germination speed (MGS), number of leaves per seedling (NL), height of the aerial part of the seedlings (HAP) and length of the longest root (LLR). Large seeds promoted the highest means in all variables, except for MGT. The temperature of 30 °C ± 2 caused higher GSI, MGT and MGS. Large seeds resulted seedlings with better quality and when germinating in a greenhouse produced seedlings with higher NL, HPA and LLR. Higher germination temperatures promote faster development of Plinia peruviana.

As sementes foram classificadas em três tamanhos: pequenas (≤ 0,6 cm de diâmetro), médias (0,6 - 1,0 cm) e grandes (≥ 1,5 cm), sendo semeadas em caixas plásticas contendo como substrato vermiculita e Plantimax® (1:1). As caixas foram distribuídas em duas condições de temperatura: ambiente (22 ºC ± 2) e estufa (30 ºC ± 2). O experimento foi conduzido em delineamento inteiramente casualizado. Após 45 dias, avaliou-se a germinação (%), índice de velocidade de germinação (IVG), tempo médio de germinação (TMG), velocidade média de germinação (VMG), número de folhas por plântula (NF), altura da parte aérea das plântulas (APA) e comprimento da maior raiz (CMR). As maiores médias em todas as variáveis foram obtidas com sementes grandes, exceto para TMG. A temperatura de 30 °C ± 2 ocasionou maior IVG, TMG e VMG. Sementes grandes resultaram em mudas de melhor qualidade e quando colocadas para germinar em estufa originaram plântulas com maior NF, APA e CMR. As temperaturas mais elevadas de germinação promovem o desenvolvimento mais rápido de Plinia peruviana.Embrapa Florestas2023-08-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/octet-streamhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/220510.4336/2023.pfb.43e202102205Pesquisa Florestal Brasileira; v. 43 (2023)Pesquisa Florestal Brasileira; Vol. 43 (2023)1983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/2205/1698Copyright (c) 2023 Charlene Moro Stefanel, Paola Daiane Welter, Tamara Trentin Weiss, Hazael Soranzo de Almeida, Raviel Afonso Dickel, Renato Trevisanhttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessStefanel, Charlene MoroWelter, Paola DaianeWeiss, Tamara Trentin Almeida, Hazael Soranzo deDickel, Raviel AfonsoTrevisan, Renato2023-03-16T12:47:49Zoai:pfb.cnpf.embrapa.br/pfb:article/2205Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2023-03-16T12:47:49Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
