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...
Rooting of herbaceous cuttings of Malpighia emarginata D.C. (CAMB-06 and APU-04...
Mühlbeier,Débora Thaís; Koyama,Renata; Chaves Junior,Osmar Jose; Hussain,Ibrar; Stenzel,Neusa Maria Colauto; Roberto,Sérgio RuffoAbstract The objective of this work was to evaluate the rooting of herbaceous cuttings of CAMB-06 and APU-04 acerola cherry selections associated with the use of indolebutyric acid (IBA) and a concentration of aqueous extract of coco-grass. Cuttings were treated by immersion with different concentrations of IBA (0; 1,000; 2,000; 3,000; 4,000 mg L-1) and one application of aqueous extract of coco-grass in propor...
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...
Export and nutrient partitioning in organic onion
Bettoni,Marcelle Michelotti; Mógor,Átila Francisco; Pauletti,Volnei; Silva,Vitor Cezar Pacheco da; Koyama,RenataABSTRACT Early season onion crops, despite lower yield, is an opportunity for farmers to explore market and better prices in southern Brazil. Knowing the amount absorbed and the distribution of nutrients in the plant is essential for adequate management of fertilization. However, little information on this matter is available for onion, especially for organic farming and nontraditional periods in southern Brazi...
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...
Indole butyric acid and substrates influence on multiplication of blackberry 'X...
Hussain,Ibrar; Assis,Adriane Marinho de; Yamamoto,Lilian Yukari; Koyama,Renata; Roberto,Sérgio RuffoBlackberry is a shrubby plant specie which has a high economic importance among agriculture crops. Brazil is the major country of Latin America with the highest future scope for blackberries. For availability of good quality and maximum quantity of seedlings, the present study was carried out at the Universidade Estadual de Londrina,PR from January to March in 2013. The aim of the study was to evaluate the mult...
Substratos no enraizamento de estacas herbáceas de amora-preta Xavante
Yamamoto,Lilian Yukari; Koyama,Renata; Borges,Wellington Fernando Silva; Antunes,Luís Eduardo Corrêa; Assis,Adriane Marinho de; Roberto,Sérgio RuffoA amora-preta (Rubus spp.) destaca-se entre as espécies que apresentam boas perspectivas de cultivo em áreas de agricultura familiar. Visando a otimizar a multiplicação de mudas dessa espécie, o objetivo deste trabalho foi avaliar o uso de substratos e concentrações do ácido indolbutírico (AIB) no enraizamento de estacas de amora-preta Xavante. O delineamento experimental foi o inteiramente casualizado em arran...
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...
