| Description
| - Studovali jsme vzájemné působení mezi volnými radikály, cytokininy a ethylenem během stárnutí děložních listů fazolu. Byl sledován časový průběh hladin cytokininů, ethylenu a konečných produktů po napadení volnými radikály, tzv. lipofuscinoidních pigmentů (LFP) u rostlin s modifikovanou délkou života. Tyto pokusy nepotvrzují zásadní roli žádného ze sledovaných parametrů v regulaci senescence děložních listů. Přechodný vzrůst LFP má vlastnost signálu pro senescenci pouze u kontrolních rostlin. Je patrné, že senescence u děložních listů je regulována jinými mechanismy než v listech. (cs)
- During ageing of bean (Phaseolus vulgaris L.) cotyledons in plants with modified life span the time-course of four cytokinins, ethylene, and the end products of free radical attack, lipofuscin-like pigments (LFP), were studied. UV irradiation shortened cotyledon life span, while epicotyl decapitation prolonged it. In controls, LFP increased at the senescence onset but at the end of life span it returned to the initial level. Ethylene increased more than 3-fold at the time of abscission. The content of individual cytokinins (zeatin, zeatin riboside, isopentenyl adenine, isopentenyl adenine riboside) varied differently during ageing but they did not decreased in any case under level observed in young cotyledons at the time of abscission. UV irradiation resulted in 14-fold increase in LFP concentration at the end. Ethylene increased 8-fold 2 h after irradiation. Individual cytokinins increased after UV irradiation to a different extent and time-course, nevertheless cotyledon life span ...
