GADOTTI, Gizele Ingrid; CORREA, Carla Lima; LUCCA FILHO, Orlando Antônio  and  VILLELA, Francisco Amaral. Physiological and sanitary quality of borecole broccolis seeds benefited on densimetric table. Rev. bras. sementes [online]. 2006, vol.28, n.2, pp.123-127. ISSN 0101-3122.

The results of developed research demonstrate the efficiency of the densimetric table in the improvement of the quality of seed lots of diverse species, evidencing superior physiological and sanitary quality of the seeds in the upper positions in relation to the lower positions of the discharge zone. Considering the few reports on the improvement of vegetable seeds, especially borecole broccolis and, moreover the desuniformity of maturation of this species, that is reflected in the specific weight of the seeds, is important to study the influence of the use of the densimetric table on the performance of borecole broccolis seeds. The present study was carried out to verify the physiological and sanitary quality of borecole broccolis seeds, benefited by the densimetric table. The seeds had initially been cleaned in an air machine and sieved and then benefited on the densimetric table. The terminal axle of discharge of the 1.00m wide densimetric table was divided into four parts. The treatments consisted of the fractions obtained in the feed deposit and the high, intermediate high, intermediate decrease and low parts of the discharge zone of the densimetric table. The borecole broccolis seeds unloaded in the high part of the discharge zone of the densimetric table presented significantly superior physiological quality to the seeds unloaded in the lower part, and the intermediate fraction decrease, and the removal of the fraction directed for the part low is recommended to improve the physiological and sanitary attributes of the lot.
