研究目的(著者による)

To determine the protective role of microwaves on the stress resistance of plants to enhanced ultraviolet B radiation.

詳細情報

Plant seeds were divided into four groups: 1) control group; 2) microwave irradiation; 3) ultraviolet B radiation; and 4) microwave exposure followed by ultraviolet B radiation (seeds were germinated and grown and when they were approximately ten days old the ultraviolet-B radiation was performed for eight days).
The experiments were replicated independently six times.

研究の主なアウトカム(著者による)

Microwave pretreatment of seeds enhanced ultraviolet-B stress resistance by decreasing the concentration of malondialdehyde and increasing the concentration of ascorbic acid and ultraviolet-B-absorbing compounds, increasing the enzyme activities of catalase, peroxidase and superoxide dismutase and increasing the energy accumulation of photosynthesis.
The results suggest that microwave irradiation enhances plant metabolism and results in increased ultraviolet-B stress resistance.
