工頻電場暴露對玉米生長發(fā)育及生化物質(zhì)的影響
[Abstract]:UHV power grid is one of the core of the development of global energy Internet. The biological effect of power frequency electromagnetic field generated by power grid has become the focus of attention. Therefore, the experiment of electric field exposure of maize in field was carried out. Three exposure groups (electric field intensity were 2 kV/m,10 kV/m and 15 kV/m) and one control group (background electric field) were set up. The electric field intensity was close to 0), the morphological index, biochemical material and protective enzyme activity of maize were measured periodically, and the data were analyzed by AVONA test. The results showed that there was no significant difference in plant height and stem diameter between the exposed group and the control group, but there was no significant difference in the total functional leaf number and chlorophyll content between the exposed group and the control group, and there was no significant difference in dry matter and 1000 grain weight between the exposed group and the control group. The total protein of maize during the whole growth period was stable, the soluble sugar and total amino acid were not significantly decreased, but the soluble sugar and total amino acid of the exposed group and the control group were different in different growth stages, and there was no relationship between the total protein and the electric field intensity. Superoxide dismutase (SOD),) peroxidase (POD), catalase (CAT), glutathione S-transferase (GST), the four protective enzymes, were not significantly increased. However, the activities of four protective enzymes in the exposed group and the control group were different in different growth stages, and there was no correlation between the four protective enzymes and the electric field intensity. It is concluded that the total amino acid, soluble sugar and four protective enzymes of maize were disturbed by the electric field intensity of 2 kV/m,10 kV/m and 15 kV/m, respectively. But it did not affect the photosynthesis, growth, development and yield of maize.
