Trichomes Size and Structure in Sunflower (Helianthus annuus L.) Leaf under Nitrogen Deficiency

Two types of glandular trichomes i.e. Capitate triangular glandular and Capitate globular glandular were recorded in sunflower. Nitrogen availability regulates globular glandular trichomes development from epidermal cells by cell division via cross talk of cytokinin in roots to plant metabolic pathways in leaves. The size of trichomes on sunflower leaves may be altered with the amino acid composition and levels mobilized from older leaves under nitrogen deficiency. Therefore, Trichome development is controlled by external fertilizer availability and internal plant processes involving carbon and nitrogen metabolism and phytohormones associated with these biosynthetic pathways.
