Some Forms of Phosphorus in Wheat Grain and Their Dependence on Mineral Nutrition

Abstract

The contents of some forms of phosphorus (lipid, soluble, phytin, nucleic) were investigated in grain of wheat, variety “Mara”. The plants were grown in water culture using a Reid‐York nutritive solution. After 15 or 30 days one of the following elements was eliminated: nitrogen, phosphorus, sulphur, calcium or magnesium. The results show that the phosphorus contents of the different forms were lower in grain from the field than in that from the water cultures. The deficiency of the individual elements during vegetation affected the grain weight and the contents of the investigated forms of phosphorus, which fact indicates that different mineral nutrients have different effects on the metabolism of phosphorus.
