Effect of boron deficiency on the soluble nitrogen and carbohydrate content of alfalfa
1943
Scripture, P.N. | McHargue, J.S.
1. Alfalfa was grown in purified sand culture in the greenhouse under conditions where boron was deficient. Extracts of the plant tissue were obtained by means of a press and analyzed for nitrogeneous constituents and reducing sugars. 2. Soluble nitrogen compounds, including amides, ammonia, and nitrogen in other forms, were found to be present in larger proportions in the boron-deficient plants than in those growing normally. 3. Sugars were found to be present in excess in the boron-deficient plants. 4. The possibility that boron may be involved in protein metabolism is suggested.
