| There are many gaps for the assessment of seed vigor in vegetable crops, among these the parsley. In this context, the accelerated aging test is recognized as one of the most widely used to evaluate seed physiological potential of various crop species, being able to provide information with a high degree of consistency. Thus, the objective of the present study was to evaluate the methodology of accelerated aging test to check parsley seed vigor, as well as verify the possibility of using NaCl solutions as an alternative to control seed water uptake during the aging period without reducing test sensitivity. Four lots of parsley seeds were tested for germination, seedling emergence, and accelerated aging for 48, 72 and 96 h (traditional and NaCl solutions).... |

| ABSTRACT This study aimed at assessing the quality of the physiology and health of the coriander seeds processed in a gravity table. This was investigated at two settings namely, I with angle X 3.5° and angle Y 3.1° and II with 3.9° and 2.7° angles, with five gravity table discharges (high, high intermediate, intermediate, low intermediate and low) besides feeding. The experiment adopted the 2x6 factorial scheme, in a completely randomized design, with four replications. Two coriander seed batches of cultivar Verdão were used. The gravity table was adjusted to have 2.9 m s-1 air speed on the platform. The seed fractions discharged in the lower portion of the gravity table revealed poorer physiological performance than that of the others. Regulation I... |

| ABSTRACT: The aim of this paper was to verify the viability of digital image processing in the measurement of rice seedling and its potential use as seed vigor test. The experiment took place at the Laboratório Didático de Análise de Sementes, located in Capão do Leão (RS), using seeds of eight rice cultivars: Irga 424, Puitá Inta CL, BRS Esmeralda, SCS 116, Guri Inta CL, BRS Pampa, BRSGO Serra Dourada and Olimar. An image processing system (IPS) was used to measure length and area of shoot and root as an index of seed vigor in rice seeds. The experiment design was completely randomized with five replications. The evaluated variables were root and shoot length in graded ruler and by image, root and shoot area, and field emergence. Results obtained with... |
