Armazenamento a frio e aplicação de reguladores vegetais no enraizamento de estacas radiculares e caulinares de framboeseira Ciência Rural
Tiberti,Andrei Spaziani; Bianchini,Flávio Gabriel; Pio,Rafael; Curi,Paula Nogueira; Moura,Pedro Henrique Abreu; Tadeu,Maraísa Hellen.
The objective of this research was to verify the potential rhizogenic stem cuttings and root of raspberry (Rubus idaeusL.). Cuttings of 'Batum' cultivar was stored cold (4°C) for 10, 20 and 30 days, and a control without storage. Subsequently, the cuttings were treated with indolebutyric acid (IBA) at 0, 1000, 2000, 3000 and 4000mg L-1 and root cuttings with benzylaminopurine (BAP) at 0, 300, 600, 900, 1200 and 1500mg L-1 by 10 seconds. The cuttings were buried in 2/3 of its length in the vertical position, and root was completely buried in the horizontal position at three inches deep. It was used vermiculite medium as substrate, and these experiments were conducted in a greenhouse with 50% shading. Evaluations were made ​​75 days after planting the...

Boric acid in germination of pollen grains and fruit set of peach cultivars in subtropical region Rev. Ciênc. Agron.
Souza,Filipe Bittencourt Machado de; Pio,Rafael; Tadeu,Maraísa Hellen; Zambon,Carolina Ruiz; Gregory,L. Reighard.
ABSTRACT The pollination and fertilization process directly affects the crop yield of peach. Previous studies have shown that some cultivars lack consistent cropping (yield variation) in subtropical regions. The application of boric acid at flowering can minimize this problem. This study quantified the germination of pollen grains and fruit set on 18 cultivars of peach in a subtropical region when treated with boric acid at bud. The initial spray treatments were three concentrations of boric acid (400 mgL-1, 800 mgL-1 and 1,200 mgL-1) plus a control treatment of water. Treatments were sprayed on the shoots when the flower buds were flower bud swelling on early maturing cultivars Aurora 2 and Doçura 2. There is a cultivar difference where 'Aurora 2' had a...

Description of blackberry fruit growth by nonlinear regression models Rev. Bras. Frutic.
Silva,Édipo Menezes da; Tadeu,Maraísa Hellen; Silva,Victor Ferreira da; Pio,Rafael; Fernandes,Tales Jesus; Muniz,Joel Augusto.
Abstract Blackberry is a small fruit with several properties beneficial to human health and its cultivation is an alternative for small producers due to its fast and high financial return. Studying the growth of fruits over time is extremely important to understand their development, helping in the most appropriate crop management, avoiding post-harvest losses, which is one of the aggravating factors of blackberry cultivation, being a short shelf life fruit. Thus, growth curves are highlighted in this type of study and modeling through statistical models helps understanding how such growth occurs. Data from this study were obtained from an experiment conducted at the Federal University of Lavras in 2015. The aim of this study was to adjust nonlinear,...

Peach cultivars from tropical regions: characterization and processing potential Ciência Rural
Curi,Paula Nogueira; Tavares,Bruna de Sousa; Tadeu,Maraísa Hellen; Melo,Evaldo Tadeu de; Pio,Rafael; Souza,Vanessa Rios de.
ABSTRACT: In order to increase the availability to consumers and add even more value to peaches (Prunus persica (L.) Batsch) and to identify which cultivars grown in tropical regions are more suitable for jelly processing, the objective of this study was to characterize and evaluate the influence of different peach cultivars (‘Aurora’, ‘Biuti’, ‘Bonão’, ‘Centenário’, ‘Diamante’, ‘Douradão’, ‘Libra’, ‘Régis’ and ‘Tropical’) cultivated in tropical regions on the physicochemical characteristics, rheological properties and sensory acceptance of the resulting jelly. The evaluated cultivars presented great variability among themselves in relation to the physical and physicochemical characteristics. The jellies elaborated from these cultivars; although,...

Produção de amora-preta e amora-vermelha em Lavras - MG Ciência Rural
Curi,Paula Nogueira; Pio,Rafael; Moura,Pedro Henrique Abreu; Tadeu,Maraísa Hellen; Nogueira,Paulyene Vieira; Pasqual,Moacir.
O cultivo de amoras está amplamente difundido em zonas temperadas, porém, algumas cultivares são de baixa necessidade em frio e podem ser exploradas em locais com temperaturas mais elevadas. Assim, objetivou-se, com o presente trabalho, avaliar a produção de amoras-pretas e amora-vermelha na região de Lavras-MG (clima Cwb). O delineamento experimental foi em blocos ao acaso, com quatro blocos e onze tratamentos (cultivares de amoreiras-pretas 'Arapaho', 'Xavante', 'Ébano', 'Comanche', 'Caingangue', 'Choctaw', 'Tupy', 'Guarani', 'Brazos', 'Cherokee' e a amoreira-vermelha, espécie nativa do Brasil). Em cada parcela, foram coletados dados fenológicos e produtivos no ciclo de produção 2010/11 e 2011/12, além da caracterização físico-química dos frutos. As...
