Provedor de dados: Planta Daninha
Autores: GRAAT,Y.; BACHA,A.L.; NEPOMUCENO,M.P.; ALVES,P.L.C.A.
ABSTRACT: This study aimed at evaluating the effects of different desiccation periods of Urochloa decumbens on the initial development of Eucalyptus urograndis (clone C-219H). The experiment was conducted in 100 liter concrete boxes, previously filled with Dark-Red Latosol. U. decumbens was sown in all plots, except for the control sample without covering. After 95 days from sowing, the herbicide glyphosate (dose of 1,424 g a.e. ha-1) was sprayed at intervals of 0 (Apply-Plant), 7, 14, 21, 28 and 35 days before eucalyptus planting, plus a control sample without covering, totaling seven treatments. A completely randomized design with six replications was used. Eucalyptus plants were evaluated 30, 60 and 90 days after planting (DAP), when the height of the...

Effect of Trinexapac-Ethyl, at Two Application Timings, on the Initial Development of Eucalyptus under Water Deficit
Provedor de dados: Planta Daninha
Autores: BACHA,A.L.; MARTINS,P.F.R.B.; ALVES,P.L.C.A.; PAULA,R.C.
ABSTRACT: Eucalyptus plants are sensitive to stress during their initial development, and water deficit is the most important one. Thus, the hormetic effect caused by the application of chemical products may be a factor that allows plants to tolerate such stresses. The objective of this study was to evaluate the effects of trinexapac-ethyl on the initial growth of Eucalyptus urophylla (Clone I-144), under water deficiency, at two application timings (before planting - BP; and after planting - AP). Two experiments were conducted simultaneously in a greenhouse for 74 days after planting (DAP) eucalyptus in 15 L pots. Treatments consisted of three trinexapac-ethyl doses (0.0, 30, and 60 g a.i. ha-1) and two water conditions (with and without water deficit). A...
