Polyphenols content and seed vigor interaction in spring barley (Hordeum vulgare L.)

Popis výsledku v původním jazyce

Drought and cold stress are main factors influencing germination of barley in spring. The aim of this work was to investigate whether higher content of polyphenols in seeds affects vigor and germination ability. For the purpose of this study ten varieties from different growing areas were selected while seed vigor was determined by two different methods. The first method was conventional germination method, where seeds were placed on filter paper in germinated trays whereas the second method was that barley kernels were placed in Petri dishes without filter paper under the same environmental conditions. Effect of drought and cold stress was simultaneously monitored. Drought stress was performed with addition of polyethylene glycol (PEG) solution with osmotic potential of - 0.2 MPa and for the cold stress seeds were germinated at 10 oC. Evaluated parameters were root length and surface area performed with WinRhizo (Régent Instruments Inc., Quebec, Kanada) software while the content of total polyphenols in the grains was determined spectrophotometrically from the previously prepared extract.
