Incidence of P, Mn and B deficiencies on the levels of the whole and individual flavonoid groups in tomato leaves

Abstract

Alterations occur in the normal content of total and individual flavonoids with P, Mn and B deficiencies, in tomato leaves.

P and Mn deficiencies do not alter the total flavonoid level. Nevertheless, these deficiencies lead to different contributions of each flavonoid group (flavonols, flavones and flavanones) to the whole content.

B deficiency produces a very significant increase in total flavonoid content. Compounds that contribute the most to this accumulation are flavones.

Key words:

• Flavonols
• flavones
• flavanones
• flavonoids
• P‐deficiency
• Mn‐deficiency
• B‐deficiency
