Effect of boron concentration in the nutrient solution on the soluble and insoluble nitrogen fractions of spinach
1944
Scripture, P.N. | McHargue, J.S.
1. Spinach plants were grown in sand cultures with boron supplied in the nutrient solution at the following rates: 0.25, 0.50, 1.00, and 5.00 p.p.m. 2. The soluble nitrogen was extracted from the fresh plant material with 50% ethyl alcohol and the percentages of soluble and insoluble or protein nitrogen determined. 3. As the boron concentration of the nutrient solution was increased, the rate of protein synthesis tended to increase.
