Seed vigour effected by total polyphenols content

Original language description

Phenolic compounds are important products of secondary metabolism in plants and cannot be synthesized in the human body, so they are mainly taken from food. For the performance of crop seeds a key is the complex trait of seed vigour. It defines their ability to emerge across diverse environmental conditions. It was published, an increase in total phenolic content correlated with enhanced seed vigour in some plant species. The aim of this work was to investigate whether higher content of total polyphenols in seeds affects seed vigour. For the purpose of this study four varieties of spring barley from four localities were tested. Seed vigour was conducted in two ways: in the first one, seeds were placed between two layers of germinating paper in the germinating box, whereas in the second barley kernels were placed in Petri dishes without filter paper under the same environmental conditions. Effect of drought and temperature stress (10°C) was simultaneously induced. Drought stress -0.5 MPa was induced using polyethylene glycol (PEG 6000). Evaluated parameters for seed vigour were root and plumula length and surface area performed through digital image analysis with WinRhizo software. The content of total polyphenols in the grains was determined spectrophotometrically from the previously prepared extract. The total polyphenols content (TPC) was significantly affected both by variety and locality. The statistically significant correlation between total polyphenols content and seed vigour was found.
