Abstract

Effects of magnesium fertilizer application on the contents of sugar, amino acid and protein in the pulp and pericarp of magnesium- deficient grapevines were studied under the field condition, in order to provide reference basis for formulating fertilization of grape. A field experiment with split plot design was conducted in which four plots of land set up in main district applied magnesium sulfate separately: 0kg/hm2, 112.5kg/hm2, 150kg/hm2, 187.5kg/hm2, while three blades were used in the deputy district to spray magnesium sulfate with different concentration: 0%, 0.2%, 0.4%. The results showed that the soluble sugar content in pulp of grapes was higher than that in pericarp, but the content of free amino acid and soluble protein was much lower than that in pericarp. The content of magnesium in grapes of magnesium-deficient grapevines was reduced, and the content of soluble sugar and soluble protein in grape pulp and pericarp was reduced, while the content of amino acid was accumulated. Proper application of magnesium can improve the content of magnesium in fruits, increase the content of soluble protein and soluble sugar in pulp and pericarp, and reduce the content of free amino acids. The treatment of S2F0.4 (i.e. 150kg/hm2 magnesium sulfate fertilizer applied in autumn, and 0.4% magnesium sulfate fertilizer sprayed on leaves in mid-May, mid-June and mid-July) has higher magnesium content in fruits and higher soluble protein and sugar content in pulp and pericarp, which is the best magnesium supplementation measure under this soil environment.
