Methods of application of indolebutyric acid and basal lesion on ‘Woodard’ blue...
Higuchi,Maíra Tiaki; Ribeiro,Luana Tainá Machado; Aguiar,Aline Cristina de; Zeffa,Douglas Mariani; Roberto,Sergio Ruffo; Koyama,RenataAbstract Blueberry cuttings are difficult to root, so alternatives that maximize their rhizogenic potential are essential for the expansion of the crop. The objective of this work was to evaluate the effect of the basal lesion and different methods of indolebutyric acid (IBA) on the rooting of ‘Woodard’ herbaceous cuttings, collected in two seasons. The experimental design used was completely randomized in a 3x...
Performance of ‘Valência’ sweet orange grafted on trifoliate orange hybrid root...
Domingues,Allan Ricardo; Marcolini,Ciro Daniel Marques; Gonçalves,Carlos Henrique da Silva; Silva,Carlos Eduardo Alves da; Roberto,Sergio RuffoAbstract The objective of this work was to evaluate tree size, production, and fruit quality of ‘Valência’ sweet orange (Citrus sinensis) grafted on various trifoliate orange rootstocks, in order to select genotypes with a high performance. Twenty rootstock genotypes were evaluated, including trifoliate orange hybrids with mandarin (citrandarins) and with grapefruit (citrumelos), as well as ‘Rangpur’ lime. The ...
Dwarfing-canopy and rootstock cultivars for fruit trees
Donadio,Luiz Carlos; Lederman,Ildo Eliezer; Roberto,Sergio Ruffo; Stucchi,Eduardo SanchesAbstract As fruit trees generally have a large size, the production of small or even dwarf trees is of great interest for most of fruit crops. In this review, some of the main tropical, subtropical and temperate fruit trees that have small or even dwarfing cultivars are approached. The causes of dwarfism, although the use of dwarfing rootstocks, is the main theme of this review. The factors that affect the size...
Postharvest longevity of 'BRS Vitória' seedless grapes subjected to cold storag...
Colombo,Ronan Carlos; Souza,Reginaldo Teodoro de; Cruz,Maria Aparecida da; Carvalho,Deived Uilian de; Koyama,Renata; Bilck,Ana PaulaAbstract: The objective of this work was to evaluate cold storage periods and postharvest longevity of the seedless table grape 'BRS Vitória' subjected to the application of the disease-resistance inducer acibenzolar-S-methyl (ASM). Bunches were treated or not with 1% ASM, placed individually in plastic clamshell trays and stored in a cold chamber at 2±1ºC, at a high relative humidity, for three periods (30, 45...
Berry-cluster thinning to reduce compactness of ‘Black Star’ table grapes
Roberto,Sergio Ruffo; Mashima,Cesar Hideki; Colombo,Ronan Carlos; Assis,Adriane Marinho de; Koyama,Renata; Yamamoto,Lilian Yukari; Shahab,MuhammadABSTRACT: The berry-cluster thinning technique was evaluated at different phenological times to prevent bunch compactness of ‘Black Star’ table grape, a new somatic mutation of ‘Brasil’ grape. The trial was carried out during 2012 and 2013 seaons in a vineyard situated in Marialva, PR, Brazil. Vines were trained in an overhead trellis system and spaced at 3x4m. The randomized block design was used as a statisti...
Color of berry and juice of 'Isabel' grape treated with abscisic acid in differ...
Yamamoto,Lilian Yukari; Koyama,Renata; Assis,Adriane Marinho de; Borges,Wellington Fernando Silva; Oliveira,Izadora Rodrigues de; Roberto,Sergio RuffoAbstract : The objective of this work was to evaluate the effect of (S)-cis-abscisic acid (S-ABA) application at different ripening stages, in increasing phenolic compounds and color of berry and juice of 'Isabel' grape (Vitis labrusca). The evaluated treatments were: control, without S-ABA application; 400 mg L-1S-ABA applied 7 days before veraison (DBV) + 400 mg L-1S-ABA at 35 days after first application (DA...
Ciclo de produção e demanda térmica de clones da videira 'Concord' sobre difere...
Borges,Rogério de Sá; Roberto,Sergio Ruffo; Yamashita,Fabio; Assis,Adriane Marinho de; Yamamoto,Lilian YukariO objetivo do trabalho foi determinar a duração do ciclo de produção e a necessidade térmica de seis clones de 'Concord' sobre três porta-enxertos no norte do Paraná. Foram avaliados os clones '22', '28', '49', '202', '211' e '225', obtidos pela Embrapa Uva e Vinho, e enxertados sobre os porta-enxertos 'IAC 766', 'IAC 572' e '420-A'. O trabalho foi realizado em área experimental pertencente ao Centro Tecnológic...
Produção e qualidade de frutos de clones de videira 'Concord' sobre diferentes ...
Borges,Rogério de Sá; Roberto,Sergio Ruffo; Yamashita,Fabio; Assis,Adriane Marinho de; Yamamotoi,Lilian YukariDentre as tradicionais cultivares utilizadas na elaboração de suco de uva, a 'Concord' tem se destacado pelo bom aroma e sabor que confere ao suco. Este trabalho objetivou avaliar a produção e qualidade dos frutos de seis clones de videira 'Concord'('22', '28', '49', '202', '211'e '225'), sobre três portaenxertos ('IAC 766', 'IAC 572' e '420-A'). O experimento foi realizado em Rolândia (PR), em esquema fatorial...
'Haruna': uma nova mutação somática natural da videira 'Itália'
Assis,Adriane Marinho de; Roberto,Sergio Ruffo; Yamamoto,Lilian YukariO objetivo deste estudo foi descrever as principais características físico-químicas e produtivas da uva fina de mesa 'Haruna', uma nova mutação natural originada da cv. Itália, em Uraí-PR, Brasil. O formato das bagas, elipsoide alongado bastante expressivo, é uma das características que mais difere essa nova mutação da uva 'Itália'. As bagas apresentam coloração verde-clara, tendendo ao amarelo na maturação ple...
Ethephon use and application timing of abscisic acid for improving color of 'Ru...
Roberto,Sergio Ruffo; Assis,Adriane Marinho de; Yamamoto,Lilian Yukari; Miotto,Lidiane Carla Vilanova; Koyama,Renata; Sato,Alessandro JeffersonThe objective of this work was to evaluate the effect of ethephon and of abscisic acid (ABA) application timing on the color of 'Rubi' Table grape. Eight treatments were evaluated: control, without application; ethephon 500 mg L‑1 applied seven days after veraison (7 DAV); and two concentrations of ABA (200 and 400 mg L‑1) arranged with three application timings at 7 DAV, at 15 days before harvest (DBH), and at...
