“…A contagem do número de sementes germinadas foi realizada diariamente durante 40 dias, sempre em sala de segurança com luz verde, sendo consideradas germinadas as sementes que apresentaram raiz primária com aproximadamente 2mm de comprimento (Hadas, 1976).…”

“…The water restriction acts by reducing the speed of the physiological and biochemical processes and, therefore, crambe seedlings under conditions of low moisture exhibit lower growth, thus lower accumulations of fresh matter (Hadas, 1976).…”

“…Many methodologies have been recommended to identify genotypes more adapted to the low water availability in the soil (Hadas, 1976;Campos & Assunção, 1990). One of the products most used to simulate osmotic stress in plants is polyethylene glycol 6000, which is a chemically inert and non-toxic osmotic agent that simulates low water potentials without being absorbed by the seeds, due to the large size of its molecules (Villela et al, 1991;Martinelli-Semene et al, 2000).…”

“…Germination counts were made from the third day after sowing and 3 day intervals up to the 30 th day. Seeds presenting a radicle five mm long were considered as germinated (Hadas, 1976). Data concerning to percentage and mean time of germination were submitted to factor analysis of variance (F test) with two factors, treatments and times, and the means were compared by the Tukey test at P > 0.01 (Pimentel-Gomes, 1990).…”
