Effect of Irrigation on the Germination of Bean Seeds Cv Napoli and Cv Contender

Abstract

The effect was studied of the irrigation blades on the physiological quality and uniformity of the seeds of bean, cultivars Napoli and Contender, harvested in may 2016 in an area belonging to the State University of Goiás-UEG. The experiment was installed in the Laboratory of Vegetable Production of UEG-GO. The sowing was done using four replicates of 50 seeds, distributed on three sheets of paper germitest moistened with demineralized water. Them, they were taken to germinator regulated at 25°C. The germination indexes, germination speed, hard seeds, dormant and dead, seedlings with small defect index, seeds with secondary infection, and intact seedlings were evaluated. The experimental design was a completely randomized design in a 2 x 5 factorial scheme (cultivars x irrigation blades), with 4 replicates. The physiological quality of the seeds was evaluated by means of the germination and vigor test, and the results measured in percentage. The means were compared by the Tukey test at 5% probability. The seeds that presented the highest physiological quality and uniformity in germination were from the Contender cultivar, in the 100% and 125% irrigation blades. For cultivar Napoli, the rates were 80.5% to 90% in the irrigation blades of 25% and 125%. Seeds with higher indexes showed better performance in both cultivars studied for both quality and vigor.
