The developed duplex real-time PCR method allows the simultaneous detection of traces of potentially allergenic white mustard (Sinapis alba) and celery roots (Apium graveolens var. rapaceum), celery stalks (A. g. var. dulce) and leaf celery (A. g. var. secalinum). The duplex assay does not show any cross-reactivity with 64 different biological species, including various members of the Brassicac...

Kísérletünket Kecskeméten, a kar belső tenyészkertjében végeztük 2019-ben, földbe süllyesztett, nagy-méretű (0,3 m3 -es, 0,3 m2 felületű) tenyészedényekben 4 kezeléssel, 6 ismétléssel, zeller jelző növénnyel. Akár az összes terméstömeget, akár gumótermést értékelve legnagyobb terméstömeget (g/tenyészedény) - egy eset kivételével szervestrágyás kezelés termette. Ez eredmény legkisebb adag kálium...

The effect of oven drying at 50ᵒC ± 1ᵒC for 9 hour, 70ᵒC ± 1ᵒC for 5 hour and freeze drying on retention of chlorophyll, riboflavin, niacin, ascorbic acid and carotenoids in herbal preparation consisting of 8 medicinal plants was evaluated.
