ABSTRACT: The 'Montenegrina' mandarin ( Citrus deliciosa Tenore) is widely cultivated in southern Brazil. This cultivar has a great tendency for alternate bearing, requiring thining of the fruit. However, the chemical thinners studied until now in this cultivar have not been successful. The objective of this research was to evaluate the effect of 3,5,6-trichloro-2-pyridinyloxyacetic acid (3,5,6-TPA) on the production and fruit quality of the 'Montenegrina' mandarin, in comparison with hand thinning and the options of chemical thinning previously studied. Hand thinning and no thinning were used as controls. Ethephon was applied in three doses: 200mg L-1, 300mg L-1 or 200mg L-1 + 3% urea; or 3,5,6-TPA, in four doses: 10, 20, 30 or 40mg L-1. Fruits of the... |

Tetraploid citrus rootstocks may present different morphological characteristics and growth when compared to diploid ones. This worked aimed at comparing morphological characteristics and height growth of diploid and tetraploid plants from the rootstocks 'Swingle' citrumelo [C. paradise Macf. x Poncirus trifoliate (L.) Raf], citrange 'Troyer' (C. sinensis (L.) Osb. x P. trifoliata) and citranges 'Fepagro C 13' and 'Fepagro C 37' [C. sinensis cv. Pêra x P. trifoliata] during twelve months. Diploid (2n=18) and tetraploid (2n=36) plants originated from the same seed were identified, cultivated and evaluated every 45 days regarding color, height, petiole length, leaf length and central leaflet width. Significant differences were observed for the evaluated... |

O objetivo deste trabalho foi testar a viabilidade da técnica de enxertia herbácea em frutíferas nativas da família Myrtaceae. O experimento foi realizado em casa de vegetação do Departamento de Horticultura e Silvicultura/ UFRGS, em Porto Alegre. Duas espécies de Myrtaceae nativas foram usadas, tanto como porta-enxerto quanto como enxerto, Eugenia uniflora (Pitangueira) e E. involucrata (Cerejeira-do-rio-grande ou Cerejeira-do-mato), totalizando quatro combinações. O método de enxertia adotado foi por garfagem em fenda cheia, em ramos herbáceos, com diâmetro médio do porta-enxerto de 0,1cm, enquanto os ramos dos enxertos apresentavam diâmetro médio entre 0,08 a 0,1cm, para as duas espécies. As análises foram quinzenais e, após 70 dias, foram analisadas... |

Abstract: The objective of this work was to evaluate the effect of shoot heading and of hand thinning in different development stages of flowers and fruits on the fruit production and quality of 'BRS Kampai' peach (Prunus persica) trees. The experiment was performed during three crop years, under the conditions of the “Depressão Central” region in the state of Rio Grande do Sul, Brazil, and the treatments were: T1, heading of half of the mixed shoot; T2, heading of one third of the mixed shoot; T3, flower thinning in the pink bud stage; T4, thinning at full bloom; T5, thinning of fruit with 5 mm; T6, thinning of fruit with 20 mm; and T7, no thinning or heading (control). Fruit production and quality were evaluated. Plants with no thinning were more... |

The objective of this work was to assess the effect of six rootstocks on yield, fruit quality, and growth of 'Oneco' mandarin during the first seven harvesting seasons, in Butiá, Rio Grande do Sul State, Brazil. The rootstocks evaluated were: 'Swingle' citrumelo (Citrus paradisi × Poncirus trifoliata), 'Caipira' orange (C. sinensis), 'Troyer' citrange (C. sinensis × P. trifoliata), 'Rangpur' lime (C. limonia), 'Volkamer' lemon (C. volkameriana), and 'Flying Dragon' trifoliata orange (P. trifoliata var. monstrosa). Plants budded onto 'Flying Dragon' had the lowest vegetative development, which indicates the dwarfing characteristics of this rootstock, and had the highest mean production efficiency, despite low yield. Plants grafted on 'Volkamer' lemon and... |

A tangerineira 'Michal' (Citrus clementina x C. tangerina) poderá ser uma boa alternativa ao Rio Grande do Sul como cultivar copa para produção de frutos em época precoce. No entanto, há falta de informações sobre seu comportamento em cultivo nas condições ambientais desse Estado. O objetivo deste trabalho foi avaliar o desenvolvimento das plantas, a produção e a qualidade dos frutos da tangerineira 'Michal' enxertada sobre cinco porta-enxertos: citrangeiro 'Troyer', citrumeleiro 'Swingle', limoeiro 'Cravo', tangerineira 'Sunki' e trifoliata 'Flying Dragon', na Depressão Central do Rio Grande do Sul. Foram avaliados os seguintes parâmetros: a altura das plantas, a circunferência do tronco, a área de projeção da copa (APC), o número e a massa (MF) de frutos... |

Abstract: The objective of this work was to evaluate the productive and vegetative performance of the Maciel and Chimarrita peach tree cultivars grafted on six rootstocks, in a replanting area. The experiment was carried out in an area that had been previously cultivated with peach trees for more than 15 years in the municipality of Eldorado do Sul, in the state of Rio Grande do Sul, Brazil. The Maciel and Chimarrita peach tree cultivars were grafted on 'Aldrighi', 'Capdeboscq', 'Okinawa', 'Flordaguard', 'Nemaguard', and 'Umezeiro'. The 'Umezeiro' rootstock caused high plant mortality in both scions, as well as low productivity and higher alternate bearing; it also affected the qualitative and ripening attributes of the fruits of 'Chimarrita'. The... |
