Sweet maize seeds present lower physiologic quality, when compared to regular maize seeds, due to the influence of several features, such as the seed size and shape. Thus, this study aimed at evaluating the seed physiologic quality of two sweet maize cultivars (BR-401 and BR-402), separately classified according to thickness, by using slotted screen sieves (8/64 x 3/4, 9/64 x 3/4, 10/64 x 3/4, 11/64 x 3/4, 12/64 x 3/4 and 13/64 x 3/4), and width, with round screen sieves (17/64, 18/64, 19/64, 20/64, 21/64 and 22/64). For each cultivar, sorted lots were compared with the unrated batch, following a completely randomized design, in a 2x7 factorial scheme, with four replications. The biometric parameters evaluated were sieve retention, 100 seeds weight and water content. The physiologic quality was determined according to the first counting, germination, cold test, accelerated aging, electric conductivity and seedling emergence in the field. The classification with sieves improved the physiologic quality of sweet maize seeds. Seeds with intermediate thickness, for both cultivars, generally presented greater vigor. Concerning width, larger seeds, for the BR-401 cultivar, and intermediate seeds, for the BR-402 cultivar, showed better physiologic quality.

Agronomic characteristics and commercial quality of popcorn maize cultivars. In order to identify popcorn cultivars that constitute a viable alternative For popcorn producers, an experiment was conducted using a randomized blocks experimental design with Five genotypes (BRS Angela, Zelia, IAC 112, IAC 12 and IAC TC-01) and four repetitions, during the 2003/2004 crop. The experiment was carried out with 60 cm spacing between lilies and density of 75 thousand plants per hectare. During the experiment, agronomic and commercial characteristics were evaluated, under field and laboratory conditions. The variety BRS Angela featured increased yield, followed by simple hybrids IAC, with Zelia (triple hybrid) showing lower yield. The simple hybrid IAC 12 showed the lowest commercial quality of popcorn. Grain production was positively associated with the number of grains per car and with the weigh of 1,000 grains, and negatively with the level of N(total) in grain. The commercial quality was negatively influenced by the weigh of 1,000 grains.
