ATMOSPHERIC ELECTRICITY AND PLANT NUTRITION
Based on his findings Lemström drew more general conclusions. His concept was that awns of cereals and needles of coniferous fulfil the electrical function in plants. He considered that good growth of plants in polar regions was due to electrical processes in the atmosphere which proceed more intensively in those regions. He showed that growth of trees in polar regions, as shown by their annual rings, is in good correlation with the intensity of northern lighst.
