Qualidade fisiológica de sementes e desempenho de plantas de rúcula no campo

Abstract

The study had as objective evaluates the influence of different physiologic quality seeds of Eruca sativa L. in the initial development and in the commercial production. It was evaluated the physiological quality of seeds by tests of germination, first count, speed of germination-index, root length and shoot, fresh and dry weight of seedlings. At 10 days after sowing in the field, the percentage of emergence, root lengt and shoot, fresh and dry plants was estimated. After 35 days of sowing, the number of leaves, number of leaves greater than 10 cm, fresh and dry plants was evaluated. A randomized complete block design was used with four treatments (lots) and four replications. There was stratification of lots on the physiological quality of rocket seeds. The seeds vigorous possible the further development of root and shoot at ten days after the sowing, however the physiological quality of seeds didn't affect the commercial production of the culture.
