“…As plantas em estágio inicial absorvem o B com maior intensidade em relação às plantas adultas, pelo fato do B apresentar pequena mobilidade de redistribuição dos tecidos velhos para os mais jovens (Sousa et al, 2011 maior dose de boro (4,61 g kg -1 de sementes) não promoveu efeito significativo para a matéria seca da parte aérea do girassol, sendo que esse resultado pode ser atribuído ao fato da adubação com micronutrientes possuir um limite estreito entre a deficiência e a toxidade das plantas, podendo ser influenciada de acordo com a espécie utilizada (Faquin, 2005).…”

R E S U M OA melancia apresenta pouca tolerância à deficiência de boro e seu fornecimento via tratamento de sementes pode atender a necessidade da planta e melhorar seu desenvolvimento especialmente na fase de mudas. Objetivou-se com esse trabalho avaliar o desenvolvimento inicial de mudas de melancia em função da aplicação de boro nas sementes. O experimento foi realizado em abrigo telado (50% de luminosidade), em Bom Jesus-PI no período de abril a maio de 2011. Adotou-se o delineamento em blocos casualizados, com os tratamentos: 0,0; 4,24; 8,50; 17,00; 34,00 g de B kg -1 de sementes, com cinco repetições e cinco plântulas por parcela experimental. Foram utilizados como recipientes tubetes com capacidade para 50 cm 3 , preenchidos com substrato constituído de solo (Latossolo Vermelho), areia lavada e esterco bovino na proporção (1:1:2), respectivamente. No final do experimento, avaliou-se: i) a altura da planta; ii) diâmetro do caule; iii) matéria seca de raiz e da parte aérea (g planta -1 ); iv) clorofila; v) comprimento da raiz e vi) volume radicular. A aplicação de boro nas sementes influenciou positivamente as variáveis altura da planta, clorofila, matéria seca da parte aérea, comprimento radicular e volume radicular. A dose de 25,5 g de B kg -1 de sementes é recomendada para maior produção de matéria seca das mudas. Palavras-chave: ácido bórico, adubação via semente, olerícola. A B S T R A C TWatermelon has little tolerance to boron deficiency and supply via seed treatment can meet the need of the plant and improve its development especially in the seedling stage. The objective of this study was to evaluate the initial development of watermelon seedlings due to boron application in seeds. The experiment was conducted under greenhouse conditions (50% brightness) in Bom Jesus-PI from April to May 2011. A randomized complete block design was adopted with treatments: 0.0; 4.24; 8.50; 17.00; 34.00 g of B kg -1 of seeds, with five replications and five seedlings per experimental plot. There were used containers with a capacity of 50 cm 3 , filled with a substrate composed of soil (Oxisol), washed sand and manure in the ratio (1:1:2), respectively. At the end of the experiment, it was evaluated: i) the height of the plant; ii) stem diameter; iii) dry matter of root and shoot (g plant -1 ); iv) chlorophyll; v) root length and vi) root volume. The application of boron in the seeds positively influenced the variables plant height, chlorophyll, dry matter of shoot, root length and root volume. The dose of 25.5 g of B kg -1 of seeds is recommended for higher dry matter production of seedlings.

“…The addition of this variable may be related to the favoring of chemical and physical properties of the substrate (Table 1), mainly for the supply of calcium which has an important role in plant growth due to its performance in the cell division and elongation (Villas-Boas, 2014). In a research conducted by Souza et al (2011), regarding the growth of passion fruit seedlings (Passiflora edulis) with boron-based and termite mound material fertilization, the maximum plant height (14.1 cm) could be achieved with doses of 75 g dm -3 of termite mound material, with 0.76 mg dm -3 of B. Regarding the number of leaves per plant (NL), all treatments with termite mound material were effective in increasing this variable, especially the T 5 : termite mound material (100%), which showed NF values 60% higher than T 1 : washed sand (100%) (Fig.…”

“…The application of termite mound material during the plant growth is not a common practice, but in some studies, positive results were verified by this practice adopted by some low-income producers from northern Brazil (Souza et al, 2011). Researches with termite mound material have been held with lettuce (Oliveira and Paiva, 1985), sorghum (Novelino et al, 2001) and passion fruit (Souza et al, 2011) and have shown satisfactory results.…”

A quality substrate is essential to ensure the proper conditions for the emergence and early development of seedlings. The aim of the present study was to evaluate different proportions of termite mound substrate in the emergence and early development of tomato seedlings. The experiment was performed in a completely randomized design, with five treatments constituted by the substrates, with four replications: T 1 : Washed sand (100%); T 2 : Washed sand (75%) + termite mound material (25%); T 3 : Washed sand (50%) + termite mound material (50%); T 4 : Washed sand (25%) + termite mound material (75%) and T 5 : termite mound material (100%). The Santa Clara cultivar (tomato) of Topseed ® was used. The seeds were distributed in gerbox boxes. Emergence, emergence speed index, shoot height, number of leaves, shoot dry mass, root length and root dry mass of tomato seedlings development were evaluated after 25 days. The use of termite mound substrates is a viable alternative to the emergence and development of tomato seedlings. In general, the substrate of termite mound material (100%) was the most promising in the increment of all variables.
