Abstract

Abstract Citriculture is an important alternative for the agribusiness development in the state of Paraná, Brazil. However, the use of a few cultivars of scion and rootstock restricts the harvest period and increases the vulnerability to pests and diseases. This study aimed to evaluate the vegetative growth, production and fruit quality of ‘Cadenera’ orange trees (Citrus sinensis (L.) Osbeck ) grafted on five rootstocks, during nine harvests, under a subtropical environmental condition. The experimental design was randomized blocks with six replications, two plants per plot, and five rootstocks: ‘Rangpur’ lime (C. limonia Osb.), ‘Cleopatra’ (C. reshni hort. ex Tanaka ) and ‘Sunki’ mandarins (C. sunki hort. ex Tanaka (L.) Raf.), ‘Swingle’ citrumelo [C. paradisi Macfad. x Poncirus trifoliata (L.) Raf.], and ‘C-13’ citrange [C. sinensis (L.) Osbeck cv. Pera x P.s trifoliata (L.) Raf.]. Biometric variables, and fruit yield and quality were analyzed. The smallest canopy size was induced by ‘Rangpur’ lime and ‘C 13’ citrange rootstocks. ‘Swingle’ citrumelo and ‘C 13’ citrange provided the highest yields for the ‘Cadenera’ sweet orange trees and were superior to ‘Rangpur’ lime. Trees grafted on ‘C 13’ citrange presented the highest yield and productive efficiency.

Highlights

Material and methodsIn Brazil, citriculture is an agricultural activity of high economic and social importance
Plant development In the evaluation carried out in 2010, no significant differences were observed in the height of the ‘Cadenera’ orange trees grafted on the five analyzed rootstocks (Table 1)
For the evaluations conducted in 2016, the trees grafted on Rangpur lime and ‘C-13’ citrange rootstocks presented smaller canopy height, diameter, and volume than those grafted on ‘Swingle’ citrumelo, ‘Cleopatra’ mandarin, and ‘Sunki’ mandarin rootstocks (Table 1)

Summary

Introduction

Material and methodsIn Brazil, citriculture is an agricultural activity of high economic and social importance. Citriculture serves as an important alternative for agricultural diversification in Paraná, which ranks fourth in orange production at the national level (after the states of São Paulo, Bahia, and Minas Gerais). Orange (Citrus sinensis (L.) Osbeck) cultivars that grow best in Paraná are ‘Pêra’, ‘IAPAR 73’, ‘Folha Murcha’, ‘Valência’, ‘Navelina’, ‘Shamouti’, ‘Salustiana’, ‘Cadenera’ and ‘Jaffa’ (TAZIMA and LEITE JÚNIOR, 2002; LEITE JÚNIOR, 1992). The varieties most commonly grown in Paraná are ‘Pêra’, ‘Folha Murcha’, ‘Valência’ and ‘IAPAR 73’ that is cultivated in a smaller area. These varieties mature from the mid-season to the late-season (TAZIMA and LEITE JÚNIOR, 2002; AULER et al, 2014)
