Effects of the production methods on vigour of soybean seed

The seed accelerated ageing test is one of the most important tests for the seed vigour determination that provides establishing of the degree of germination maintenance and the determination of the seed storage longevity. The objective of the present study was to observe the effects of different production methods (organic and conventional) on seed vigour of the soybean cultivar Kaća by the application of the seed accelerated ageing test (ISTA Rules, 2016). The soybean seed was exposed to double stress conditions (temperature 41ºC, air humidity 100%) for 72h. In organic soybean seeds, stress conditions affected the increase in the number of nongerminated seeds by reducing the germination percentage. The length of the aboveground part of seedlings (121.63 mm), fresh weight (8.9 g), as well as dry weight of the above-ground part of seedlings (1.05 g) were greater in the accelerated ageing test than in the standard laboratory test, while the length (100.25 mm), fresh (1.26 g) and dry weight (0.1 g) of the root were greater in the standard laboratory test
