| Aiming at evaluating genotype influence on the concentration of protein and oil, immature seeds of cultivars CD 202 and CD 206 were removed from the mother-plant, in the stage R5, and were grown in vitro, in a liquid culture medium which contained 20, 40 and 60 mM of glutamine, during eight days. Afterwards, the concentrations of oil and protein were compared to the contents of the seeds cultivated in vivo. With a higher availability of glutamine for the seed, there was an increase of protein content. The genotypes were statistically different as far as the protein concentration was concerned,which confirmed that the genotype had influence on the concentration of protein in the seed. Oil and protein concentrations were inversely related when a variation of... |

| La aplicación de nitrógeno para la producción de brócoli suele ser ajustada con base en criterios empíricos con el riesgo de llegar a dosis excesivas. En este sentido, una alternativa para precisar la cantidad de nitrógeno que debe agregarse es a través de la evaluación cuantitativa de la demanda nitrogenada del cultivo, el suministro de nitrógeno del suelo y la eficiencia de la fertilización nitrogenada. Se realizaron dos experimentos (octubre de 2012 a enero de 2013 y abril a julio del 2013) en el Campo Experimental Tlapeaxco de la Universidad Autónoma Chapingo, México. Los factores en estudio para el primer experimento fueron: láminas de riego (3 y 6 mm) y dosis de nitrógeno (80, 160, 240 y 320 kg ha-1), y para el segundo experimento las dosis de... |
