Effect of UV-A and gamma-irradiation on the polyphenol levels in barley and pea seeds, seedlings and plants.

Original language description

In two pea cultivars (Lantra, Menhir) and barley cultivars (Krona, Kompact) changes in total polyphenol content (TP) and major phenolic acids caused by UV-A and g - irradiation were investigated. The changes were determined in seeds, seedlings and plants. In barley cultivars also content of catechol, resorcinol and phloroglucinol type compounds (CRP) was estimated. TP content was determined with Folin-Ciocalteau´s reagent, CRP with p-dimethylaminocinnamaldehyde, phenolic acids by HPLC. UV-A irradiationwas performed for 0, 24, 48 and 72 hours at l=351 nm, g - irradiation with 60Co at doses 0, 10, 20 and 40 Gy. During pea sprouting TP content increased, in barley cultivars TP stagnation was observed. UV-A irradiation caused in investigated plants an increase of TP content, g - irradiation enhanced TP content in barley but in pea decreased it. It was demonstrated statistical dependence of TP content on growth phases of plants and on doses of irradiation. CRP in sprouting seeds decreased
