Effects of production methods on seed vigour of soybean seeds

Abstract

The seed accelerated ageing test is one of the most important tests for testing seed vigour, which provides the determination of the degree of preservation for germination and the determination of the duration of the seed storage. The aim of this study was to observe effects of two different production methods (organic and conventional) on seed vigour of soybean cultivar Kaca, by the application of the seed accelerated ageing test. The seeds were exposed to stress conditions for 72 h (temperature of 45?C and air humidity of 100%). After the test was applied, the number of non-germinated seeds of organically produced soybean increased, which resulted in the reduction of the germination percentage. Compared to the standard laboratory method, after the seed accelerated ageing test was applied, the length of the seedling above-ground part (121.63 mm), fresh weight of the seedling above-ground part (8.9 g) and dry weight of the seedling above-ground part (1,05 g) were higher. Moreover, the length (100.25 mm), fresh (1.26 g) and dry weight (0.1 g) of the root were also higher. After the test was applied, the percentage of the off-type seedlings (10.75%) and non-germinated seeds (26%) was higher in conventionally produced soybean seeds, while the length of the seedling above-ground part (100.63 mm), root length (106.75 mm) and root fresh weight (1.39 g) were lower.
