Abstract

Knowing the characteristics of maize varieties becomes a strategy for an adequate crop planning, in order to extract the maximum agronomic power of each variety. The objective of this work is to know the morphophysiological and developmental parameters of maize varieties. The experiment was conducted in August 2021, in Faculdades Integradas Stella Maris (FISMA), located in the Municipality of Andradina, State of São Paulo. The design was entirely randomized, where six maize varieties were grown: XB 8010; AG 1051; Cateto Paraguay; Sweet Maize (Paraguay Soup); White Maize and Asteca Mole and with four repetitions, totaling 20 plots or pots. The hybrid varieties showed better development characteristics. The criolla variety Asteca Mole presented lower developmental characteristics. Stomatal density and functionality were expressed in an antagonistic way. Maize varieties did not present differences in internal morphology in the leaves. Correlations were found between the morphophysiological and developmental parameters in the maize varieties.
