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.

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. Como un estímulo a la producción y uso del biodiesel, las semillas de crambe constituyen hoy una de las mejores opciones para el suministro de materia prima, también son una excelente alternativa en la rotación de cultivos de otoñoinvierno. El objetivo de este estudio fue evaluar la eficiencia de la combinación de tratamientos pre-germinativos sobre el comportamiento de semillas de crambe. A partir de una muestra de semillas del cultivar FMS Brilhante, se propuso un diseño experimental completamente aleatorizado, con un esquema factorial 2 x 5. El diseño se basó en la combinación de dos condiciones estructurales: semillas con y sin pericarpio, y ambos sometidos a tratamentos pre-germinativos con y sin ácido giberélico, siendo: control (sin tratamiento); semillas pre-embebidas en agua destilada sin giberelina por 24 horas como control; y semillas pre-embebidas en solución de ácido giberélico a 4 %, en diferentes concentraciones (400; 500 e 600 mg.L-1). Se determinó el contenido de agua, primer contaje de germinación y porcentaje de germinación, emergencia de plántulas e índice de velocidad de emergencia. A partir de estos resultados se concluye que la remoción del pericarpio en semillas de crambe, cultivar FMS Brilhante, aceleró la velocidad de germinación, pero, disminuyó su porcentaje final. La pre-imbibición en ácido giberélico (400, 500 e 600 mg.L-1) por 24 horas proporcionó incrementos en la germinación y en el vigor de las semillas de crambe con pericarpio. Com o estímulo à produção e uso de biodiesel, sementes de crambe constituem hoje uma das melhores opçõ es para o fornecimento de matéria-prima, sendo também excelente alternativa para cultivo de outono-inverno visando rotação de culturas. O objeto deste estudo foi avaliar o efeito da combinação de tratamentos de pré-germinação sobre o comportamento de sementes de crambe. A partir de um lote de sementes da cultivar FMS Brilhante, foi proposto o delineamento experimental inteiramente casualizado, em esquema fatorial 2 x 5. O delineamento foi baseado na combinação de duas condiçõ es estruturais: sementes com e sem pericarpo, e ambas submetidas a tratamentos pré-germinativos com e sem ácido giberélico, sendo: testemunha (sem tratamento); sementes pré-embebidas em água destilada sem adição de giberelina por 24 horas como controle; e sementes préembebidas em solução de ácido giberélico a 4 %, em diferentes concentraçõ es (400; 500 e 600 mg.L-1). Determinou-se o teor de água, primeira contagem de germinação, porcentagem de germinação, emergência de plântulas e índice de velocidade de emergência. Diante dos resultados conclui-se que a retirada do pericarpo em sementes de crambe, cultivar FMS Brilhante, acelera a velocidade de germinação, porém, diminui a sua porcentagem final. A pré-embebição em ácido giberélico (400, 500 e 600 mg.L-1) por 24 horas proporcionou incrementos na germinação e no vigor das sementes de crambe com pericarpo.
