O experimento foi conduzido em casa de vegetação, em solução nutritiva, com o objetivo de se estudarem os efeitos da aplicação de boro, por via foliar, na produção de matéria seca e na composição mineral de tomateiro (Lycopersicum esculentum, Mill.). O experimento constou de um fatorial 2 x 3, com dois níveis de boro na solução nutritiva (270 e 1,08 ppb) e pulverização com H3BO3 a 1 g/litro, em intervalos de seis e três dias e com testemunha sem aplicação foliar. A deficiência de boro provocou necrose de pontas, ramificações e falta de alongamento de raízes; distorção, clorose e afilamento de folhas; consistência quebradiça do pecíolo e necrose e morte do ponto de crescimento apical. A deficiência contínua de boro reduziu o teor desse eleme...
