Popis: The contents of sucrose and amino acids in the leaves, phloem sap and taproots have been analysed in three experimental hybrids of sugar beet and compared with earlier analysed leaf and phloem sap contents in spinach and barley. The three hybrids accumulated sucrose and amino acids to various extents in the mature roots as well as in the young taproots (9-12 weeks). The differences in the sucrose-to-amino acid ratios in the taproots were reflected in the corresponding ratios in the phloem sap. The leaf contents of sucrose and amino acids in the three hybrids were found to be very similar to each other and also to those in spinach and barley
