Germination of seeds of different vegetable beans cultivars obtained from diversified water replacements

Abstract

The effect of water replenishment on the physiological quality and seed uniformity of Napoli and Contender bean cultivars harvested in May 2015 was studied; Contender and Japanese Yellow collected in the 2016 and 2017 harvests in the experimental area of 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 among three sheets of germitest paper, moistened with demineralized water. The rolls were taken to the germinator regulated at 25ºC. The experimental design was completely randomized with different cultivars, collection times and water replenishment, with 4 replicates. The germination indexes were evaluated; speed of germination; hard seeds; dormant and dead; index of seedlings with small defect; with secondary infection and intact seedlings. The physiological quality of the seeds was evaluated by means of the germination and vigor test and the results in percentage and the statistic using software R. Seeds from the different water replaces, cultivars and production times presented as promising for the cultivation in Ipameri-GO.
