Resumo: | Direct sowing is the most used watermelon propagation method in Brazil. Therefore, the use of treated seeds is an alternative for improving uniformity of plant stands at planting. Thus, the objective of this study was to assess the effects of seed treatments with biostimulant on the germination and vigor of watermelon [Citrullus lanatus (Thunb.) Matsum & Nakai] seeds of the cultivar Crimson Sweet. A completely randomized experimental design with four replications was used. The seed treatments consisted of six biostimulant (Agressive Desperta®) rates (0, 1, 2, 3, 4, and 5 mL kg-1). Seed germination speed index, seedling length, seedling dry weight, seedling emergence in the field, and seedling emergence speed index were evaluated. The treatment of watermelon seeds with biostimulant resulted in increases in seed germination speed and seedling length and dry weight as the biostimulant rate was increased. Seedling percentage and emergence speed increased up to the rate of 3 mL kg-1 under field conditions; however, application of higher rates resulted in phytotoxicity. |

Para tanto, o uso de sementes tratadas surge como uma alternativa para melhoria da uniformidade de estandes no plantio. Dessa forma, objetivou-se verificar os efeitos do tratamento com estimulante de crescimento em sementes de melancia (Citrullus lanatus (Thunb.) Matsum & Nakai), cultivar Crimson Sweet, sobre a germinação e o vigor. O delineamento experimental utilizado foi o inteiramente casualizado, com quatro repetições e seis doses do estimulante de crescimento, Agressive Desperta®, 0; 1; 2; 3; 4 e 5 mL kg-1 de sementes de melancia. Avaliou-se a germinação, índice de velocidade de germinação, comprimento das plântulas, massa seca das plântulas, emergência de plântulas em campo e índice de velocidade de emergência de plântulas. O tratamento de sementes de melancia com estimulante de crescimento proporcionou maior velocidade de germinação, comprimento e massa seca de plântulas, diretamente proporcional ao aumento das dosagens. Em condições de campo, houve melhora na porcentagem e velocidade de emergência das plântulas até a dosagem de 3 mL kg-1 de sementes. Dosagens superiores a essa ocasionaram fitotoxidez.Universidade Federal Rural do Semi-Árido2023-09-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/1167710.1590/1983-21252023v36n424rcREVISTA CAATINGA; Vol. 36 No. 4 (2023); 971-979Revista Caatinga; v. 36 n. 4 (2023); 971-9791983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/11677/11338Copyright (c) 2023 Revista Caatingainfo:eu-repo/semantics/openAccessOliveira, Silvia Sanielle Costa deSousa, João Filho GomesCruz, Sihélio Júlio SilvaPonciano, Vanessa de Fátima GrahBottega, Daline Benites2023-09-28T13:11:54Zoai:ojs.periodicos.ufersa.edu.br:article/11677Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:47:04.844486Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
