Physical quality of Creole seeds in Creole corn produced in Oeste Potiguar

Abstract

The objective of this study was to evaluate the weight of a thousand seeds and the moisture level of batches of corn seed (Zea mays L.) .. 15 batches of creole corn purchased in seven regions of the Western Potiguar State of RN were used. The degree of humidity was carried out using the greenhouse method at 105 +/- 3ºC for 24 hours, with two repetitions of 25 seeds. The weight of a thousand seeds was made with eight repetitions of 100 seeds for each batch from the pure seeds portion, as recommended by the Rules for Seed Analysis. The batches have a uniform degree of moisture, however, they present a high variation in the weight of a thousand seeds. Physical tests are of little significance in determining quality if not associated with physiological quality tests.
