MORPHOLOGICAL CHANGES DURING GERMINATION AND GROWTH OF RAPESEED SAMPLES (Brassica napus) EXPOSED TO NON-IONIZING RADIATION
The UV-A radiation acts on cellular constituents indirectly through oxidative mechanisms involving the radicals’ formation. These species have a relatively short lifespan, but are highly reactive, reacts with most cellular constituents: nucleic acids, proteins, lipids, polysaccharides. The rapeseed...

| description | The UV-A radiation acts on cellular constituents indirectly through oxidative mechanisms involving the radicals’ formation. These species have a relatively short lifespan, but are highly reactive, reacts with most cellular constituents: nucleic acids, proteins, lipids, polysaccharides. The rapeseed samples provided by Agricultural Research Center Secuieni, Neamţ (Romania) were irradiated with a wide band source (UV-B, UV-A, visible) with different non-radiation doses, equivalent to several hours of sun exposure. The exposure to UV radiation determines changes in the metabolism, within the growth and development processes, having positive or negative influences on plant health and vitality. The purpose of this study is to analyze different rapeseed samples in order to identify the differences according to non-radiation effect. Regarding the growth and development of height stems it has been observed that roots length and stem height of rape samples are highest at irradiation time around 280 minutes. |
