Performance of Seeds Crambe Exposed to Pre-germination Treatments
Encouraging the production and use of biodiesel, seeds of crambe today constitute one of the best options for the supply of raw material, is also an excellent alternative for autumn-winter crop rotation order. The aim of this study was to evaluate the efficiency of combined pre-germination treatments on the seed behavior of crambe. From a seed sample of FMS Brilhante cultivar, an experimental design completely randomized with a 2 x 5 factorial arrangement was performed. It was formed from combination of two structural conditions, seeds with or without pericarp, and treatments with or without giberelic acid, being: control (no treatment); seeds pre-soaked in distilled water for 24 hours as control; and seeds pre-soaked in gibberellic acid at 4 % at different concentrations (400, 500 and 600 mg.L-1). Water content, first count germination, germination, seedling emergence and emergence rate index were determined. From these results it is concluded that removal of the pericarp in seed of crambe, cultivar FMS Brilhante, accelerated the germination rate, however, decreased your final percentage. The pre-soaking in gibberellic acid (400, 500 and 600 mg L-1) for 24 hours, increased the germination and seed vigor crambe with pericarp.
