Abstract: 
  • Estudou-se os efeitos de auxilias exógenas e ácido bórico, no enraizamento de estacas de lichia (Litchi chinensis Sonn.). As estacas foram uniformizadas, com 25 cm de comprimento e 4 folhas cortadas pela metade. Cerca de 2,5 cm da base das mesmas foi mergulhado nos tratamentos: H2O; Boro 150 µg/ml; IBA 5.000 ppm, IBA 2.000 ppm; IBA 5.000 ppm + Boro 150 µg/ml; IBA 2.000 ppm + Boro 150 µg/ml; NAA 3.000 ppm; NAA 1.500 ppm; NAA 3.000 ppm + Boro 150 µg/ml; NAA 1.500 ppm + Boro 150 µ/g/ml. A estaquia foi realizada no mês de setembro (Hemisfério sul), sendo que as estacas foram colocadas em bandejas de isopor, tendo como substrato vermiculita e mantidas sob nebulização intermitente. Os resultados obtidos permitiram concluir que o IBA 5.000 ppm por 1 minuto foi o tratamento mais efetivo, proporcionando 83,33% de estacas enraizadas em 120 dias, enquanto o tratamento testemunha (H2O), apresentou somente 16,67% de estacas enraizadas.
  • The effects of exogen auxins and boric add were studied on lychee (Litchi chinensis Sonn.) cuttings. Cuttings were standardized to twenty-five cm length, with four leaves, cut in half. The bases of the cuttings were dipped of 2,5 cm in water solutions, resulting in the following treatments: H2O; Boron 150 µg/ml; IBA 5,000 ppm; IBA 2,000 ppm; IBA 5,000 ppm plus boron 150 µg/ml; IBA 2,000 ppm plus boron 150 µg/ml; NAA 3,000 ppm; NAA 1,500 ppm; NAA 3,000 ppm plus boron 150 µg/ml; NAA 1,500 ppm plus boron 150 µg/ml. Cutting was performed in September (southern hemisphere) and the cuttings were place in styrofoam trays, using vermiculite as substratum and kept under intermittent mist It was concluded that 5,000 ppm IBA for one minute was the best treatment to improve rooting (83,33%), while the control (H2O) showed only 16,67% of rooted cuttings.
