Abstract:
The study was conducted with a descriptive
experimental design in order to determine the effects of broad
spectrum ultraviolet radiation on growth factors, seedling height,
root length, chlorophyll content, organic weights, and percentage
survival, as well as gross morphological factors, leaf, stem, and
root appearance, of native sweet con seedlings. The study was
limited to the seedling stage of the plant and observations were
taken after 20 days of treatment. The results gathered show that
there was a visible manifestation of the detrimental effects of UV
on the irradiated seedlings. There were observed decreases in
the growth parameters while the gross morphological parameters
exhibited signs of wilting and stress. It was therefor concluded
that based on the observed results, UV had a detrimental effect
on the studied growth and gross morphological parameters.
