Caracterização topográfica dos folíolos medianos de cultivares de morangueiro sob altas temperaturas

Abstract

The cultivation of the strawberry is concentrated in the states of the Southeast and South of the country contributing to generating direct and indirect jobs. The opening of new frontiers in atypical climate conditions for the cultivation, such as regions having higher temperatures, has been investigated. The leaf to-pography interferes with pathogenicity and deposition of pesticides. This study aimed to analyze the perform-ance of 11 cultivars of strawberry in the tropical conditions of the Mesorregião Mata of the Pernambuco state. The cultivation was done in screenhouse where topographical characters of the median leaves of cultivars were evaluated. The experimental design was Completely randomized, with five replications, being each pot a plot. Dover, Oso Grande and Tudla cultivars showed leaves with a flatter relief. The cultivar Sweet Charlie pre-sented a more rugged topography. Considering the conditions of this experiment, the cultivars Dover, Oso Grande and Tudla were those that presented the most potential to pesticide absorptions.
