| The Brazilian market of tropical flowers has been growing broadly with a strong participation of the Northeast Region, where the State of Alagoas stands out. Among the exporting tropical cut flowers, pink ginger (Alpinia purpurata (Vieill) K. Schum) has been one of the most promising species. Aiming at delaying senescence in floral stems of pink ginger, two laboratory experiments were carried out at the Agricultural Science Center of the Federal University of Alagoas. In the first experiment, three different exposure periods (30; 60, and 120 minutes) to silver thiosulphate 1 mM were tested, followed or not by pulsing in a 20% sucrose solution, for 12 hours. In the second experiment, we evaluated the effect of adding calcium sulphate 50 and 100 mM, sodium... |

| ABSTRACT This study evaluated the selectivity of herbicides applied post-emergence on ornamental plants of Alpinia purpurata, Strelitzia reginae and Heliconia psittacorum. The study was conducted in two seasons. The experimental design was completely randomized with four replications. The treatments were: fluazifop-p-butyl (87.5 g ha-1), quizalofop-p-ethyl (75.0 g ha-1), sethoxydim (184.0 g ha-1), quinclorac (375.0 g ha-1), chlorimuron-ethyl (15.0 g ha-1), clethodim + fenoxaprop-p-ethyl (37.5 + 37.5 g ha-1), bentazon (720.0 g ha-1), fomesafen (225.0 g ha-1), and a control without any herbicide. In general, all tested herbicides and doses were selective for the three studied species. Although plants of A. purpurata and H. psittacorum have shown symptoms of... |
