Intermittent water deficit in soil and micromorphology of the ora-pro-nóbis leaf epidermis

Abstract

Considering the limited knowledge of physiology and agronomic management of Ora-pro-nóbis, we evaluate at the level of the leaf epidermal cells the response of this plant to increasing water deficits between-5 kPa and-70 kPa of soil matric potential. Material and methods The experiment was conducted in Uberlândia, Minas Gerais, Brazil (altitude 633 m, latitude 18° 45' S and longitude 48°17' W) from seedlings produced from selected cuttings (20 cm in length and diameter between 8 and 9 mm) from the same mother plant and
