The influence of seed treatment on corn germination

This paper presents a study on the influence of seed treatment on seed germination in 10 consanguineous lines and 10 simple hybrids (from KWS Ltd), grown in the area of the ​​Traian commune, Brăila county, in the 2018-2019 crop year. Seed treatment was performed with the Redigo M fungicide (100 g/l Protioconazole + 20 g/l Metalaxil) and the Langis insecticide (300 g/l Cypermethrin). In the laboratory, the germination potential was determined using the STAS 1634/1999 method, both for untreated and treated seeds and the potential of emergence was determined using the cold test method 6 ˚C, for treated seeds only. From the data analysis, the germination value varied between 93 - 95% for simple hybrids for both untreated and treated seeds, and for consanguineous lines, it varied between 92 - 95% for untreated seeds and 91 - 94% for treated seeds; the value of the cold test varied between 92 - 95% for hybrids and 91 - 93% for consanguineous lines. All hybrids and consanguineous lines recorded germination and cold test values ​​above the minimum values ​​allowed by STAS (a minimum germination value of 90% and a minimum cold test value of 85%). The treatment of corn seeds did not adversely affect their germination and viability.
