| Abstract: | Zinc deficiency caused an accumulation of 14C into malic acid, sugar phosphates, sugar nucleotides, glucose, fructose, phosphoenolpyruvate, glycine and alanine, whereas the 14C labelling in sucrose decreased. The activity of sucrose synthetase (EC 2.4.1.13) was unaffected up to the 15th day and thereafter it declined. Severe Zn deficiency reduced the biosynthesis of total protein and sucrose synthetase by 50 and 20%, respectively. |
