Permeability of peach leaf cuticles to boron

Polyol-ester impact on boron foliar absorption and remobilization in cotton and coffee trees

“…The cuticular and stomatal pathways have been studied to a certain extent, and there is no consensus that the penetration of foliar fertilizers decreases with increased cuticle wax content (Fernández and Eichert, 2009). Also, there seems to be little argument on the importance of the stomatal pathway, since the more stomata, the higher the uptake (Shu et al, 1994;Will et al, 2012). Stomata density in cotton is much lower than in coffee (Silva et al, 1989;Nascimento et al, 2006) and this could explain the difference in B absorption in this experiment.…”
