| ABSTRACT: The most widely used herbicide in coffee crop is glyphosate, it inhibits the biosynthesis of secondary metabolites, responsible for structures and substances of plant defense. This work aimed to evaluate the morphoanatomy, total phenols, flavonoids and caffeine in leaves of Arabica coffee submitted to different sub-doses of glyphosate. The treatments were combinations of three coffee cultivars (MGS Travessia, Oeiras MG 6851 and Catuaí IAC 144) and five sub-doses of glyphosate (0.0, 57.6, 115.2, 230.4 and 460.8 g a.e. ha-1). The total thickness of the leaf blade, thickness of adaxial and abaxial epidermis, palisade and spongy parenchyma, in addition to the total phenol, total flavonoids and caffeine were evaluated 30 days after spraying. Catuaí... |

| ABSTRACT Herbicide clomazone is highly soluble in water, which increases the risk of leaching, resulting in contamination of sources of groundwater and waterways, affecting non-target organisms, with possible degradation of riparian areas. The objective of this work was to investigate the possible anatomical modifications of the leaf tissue of twelve arborescent species native to Brazil grown in soil contaminated by clomazone, in order to microscopically characterize leaf damage caused by the herbicide, and investigate whether the structural damage precedes visible damage. Through micro morphometrics, the thickness and the area occupied by the tissues were measured in a cross section of the leaves of the forest species: adaxial and abaxial epidermis,... |
