Desenvolvimento inicial de diferentes variedades cítricas presentes no pomar experimental do Campus Cerro Largo, RS

Abstract

Citriculture is an activity of great importance in the world economy, in addition to fruit being commonly consumed 'in natura', the juice produced also has good acceptance in the market. Brazil is the largest producer of Orange and the largest exporter of juice, which justifies the need for studies related to culture. The objective of this work was to evaluate the initial development of citrus plants in the municipality of Cerro Largo. The experiment was carried out in the didactic orchard of the experimental area of UFFS-Cerro Largo Campus, in which five varieties of mandarins, four orange trees and two varieties were classified as acidic files. In these plants, monthly measurements were performed during the months of April to October 2018. The parameters evaluated were: plant height, crown diameter, stem circumference and vegetative vigor index (IVV). As conclusion of this work, it is inferred that, for the proposed evaluation months, for the group of Tangerines, the cultivar Dancy differed statistically for the parameters crown diameter and stem circumference. For the Acid Files, Tahiti presented the highest average height, differing from Lima-of-Persia. For evaluation of crown diameter and stem circumference, there was no significant difference. For the orange trees, there was no difference in any parameter evaluated. The highest IVV was observed for the cultivars of acidic Lima and for the cultivar of Tangerina Dancy.
