Abstract: The paper deals with the effect of mineral nutrition on the content of free flavonoid glycosides (phloridzin, hyperine) free and bound C6-C1 aldehydes (vanillin, syringic aldehyde) in the woody parts of apple shoots of the variety 'Antonovka' and on the content of products oxidized by nitrobenzene (vanillin, syringic aldehyde) in connection with the lignification of cell walls. It was established that the biosynthesis of phenolic compounds is retarded under the influenco of nitrogenous fertilizer while the biosynthesis of proteins is activated, intensifying growth. Contrary to nitric fertilizer, phosphoric with potassic fertilizers promote formation of phenolic compounds and suppress protein synthesis and growth; at the same time phenylalanine is included in the biosynthesis of lignin, but not in the biosynthesis of proteins. |
