Vigor Tests Association as an Alternative for Precise and Efficient Assessment of Maize Seed Quality

Abstract: -This study aimed to associate two concepts of seed vigor testing, the aging and seedling growth using image analysis, providing a feasible and time-saving way to evaluate maize seed vigor in large scale. For this purpose, five seed lots with different vigor levels from two single hybrids were used. The seeds were characterized by moisture content, germination, seedling emergence, seedling emergence speed index, accelerated aging and cold tests. The treatments were composed by varying the accelerated aging per… Show more

“…The drawback of our method, labor-intensity is the advantage of NRSs which bear “intelligence” of sensing. One hopeful combination is to bind automatic morphological imaging [ 34 , 42 45 ], intelligent identifying [ 46 ] and robots to replace human labor. Morphological graphing is now feasible in identifying embryo protrusion and has potential to perfect DehM: it records all details during germination and enables accurate operation [ 47 ].…”

“…Os métodos de mensuração manual com régua e por imagem, classificaram os lotes de forma idêntica, demostrando dessa forma uma confiança maior nos resultados. Dias et al (2015), ao trabalhar com sementes de milho, também conseguiram resultados confiáveis e comparáveis aos testes tradicionais, quando utilizaram medidas de comprimento de raízes de plântulas obtidas a partir da análise de imagem.…”

“…O uso de análises computadorizadas em imagens digitais de plântulas para determinação do vigor de sementes, tem sido alvo de vários estudos com diversas espécies, como trigo (Brunes et al, 2016), amendoim (Barbosa et al, 2016), milho (Dias et al, 2015), feijão (Gomes Junior et al, 2014), girassol (Rocha et al, 2015).…”

“…In this test, seeds are artificially aged by exposure to high temperatures and high humidity for a certain period of time. The AA method was useful for estimating the vigor of various plants such as wheat (Ghahfarokhi et al, 2014), maize (Dias et al, 2015), soybean (Usha and Dadlani, 2015), canola (Yin et al, 2015), safflower (Demir, 2014) and sunflower (Kibinza et al, 2006;Balešević-Tubić et al, 2007), and the percent of emergence.…”
