| Os cultivares de maçãs 'Gala' e 'Fuji' foram desenvolvidos por métodos convencionais de hibridação na década de 30 e, desde então, inúmeras variedades resultantes de mutações ocorridas naturalmente em macieiras desses cultivares têm sido identificadas (White, 1991). |

| ABSTRACT ? ?Gala? apple trees have low fruit set in restrictive pollination situations, being an obstacle to the achievement of high production rates in orchards in southern Brazil, which can be minimized by the use of growth regulators. The aim of this study was to evaluate the effect of thidiazuron concentrations in ?Royal Gala? apple fruiting and production, grown in mild winter conditions. The experiment was conducted during the 2011/2012, 2012/2013 and 2013/2014 crop years in Fraiburgo, SC, on ?Royal Gala? apple trees in Marubakaido rootstock M9 with filter. In all evaluation cycles, the experimental design was a randomized block with factorial arrangement (6x2) with six TDZ concentrations and two application forms, with six replicates, and the... |

| Burrknots are aerial root nodules that obstruct the vascularization of apple plants, which can cause depletion of the fruit tree. Usually the evaluation of the occurrence of this disorder is restricted to the rootstock region. The objective of the study was to develop a scale for the evaluation of the occurrence of burrknots in the apple trees, and to present a practical application of the developed scale. Plants with different intensities of burrknots along the stem and branches were observed, which were classified into five phenotypically distinct groups for this disorder (scale 1 to 5). In the practical application of the scale, 12 segregating populations of apple trees were phenotypically evaluated, which allowed to characterize the individual and... |

| O objetivo deste trabalho foi avaliar os níveis dos glicosídeos cianogênicos amigdalina e prunasina em 13 cultivares de pereiras asiáticas (Pyrus pyrifolia) enxertadas sobre P. calleryana e P. betulifolia, bem como verificar os seus efeitos sobre a compatibilidade de enxertia. Utilizou-se o delineamento experimental inteiramente casualizado com três repetições. Foram avaliadas as cultivares: Ya li, Shinsui, Oku Sankichi, Hakucho, Nitaka, Shinseiki, Suisei, Choujuurou, Nijisseiki, Kousui, Housui, Kikusui e Hakkou. Os glicosídeos cianogênicos não tiveram influência na compatibilidade de enxertia e no teor de clorofila das combinações entre as cultivares e os porta?enxertos. A concentração de glicosídeos cianogênicos não se mostra um marcador eficiente da... |

| Aims: Evaluate the effects of different concentrations of abscisic acid (ABA) on adult plants of productive age of ?Daiane? and ?Fuji Suprema?, to follow the ecophysiological effects and their efficiency in inducing leaf senescence, sprouting and productivity, in the Midwestern region of the state of Santa Catarina. Study Design: The experiment was arranged in a randomized block design with six replications. Place and Duration of Study: The experiment was carried out in the municipality of Caçador, Brazil (latitude 26º50?07? S, longitude 50º58?32? W, altitude 969 meters), during the growing seasons of 2013/2014 and 2014/2015. Methodology: The apple fruit tree were submitted to the following treatments: 1) Control (without treatment), 2) abscisic acid 750... |

| ABSTRACT Carbaryl or the mixture of carbaryl with NAA (naphthalene acetic acid) or BA (benzyladenine) are the post-bloom chemical thinners most widely used in apple thinning in Brazil. The marketing restriction of carbaryl demands new options of apple post-bloom thinners, requiring the evaluation of others compounds for this purpose. Metamitron is one of the substances that may be used in chemical thinning of apples. Metamitron was evaluated at two concentrations, alone or in mixture with BA, in ?MaxiGala?, ?Fuji Suprema? and ?Fred Hough? apple cultivars. Applications of metamitron at 384 mg L-1 and at 768 mg L-1 in a mixture with BA, ranging from 40 mg L-1 to 80 mg L-1, sprayed on fruits with diameter ranging from 5 to 25 mm were compared ith the standard... |

| ABSTRACT - The aim of this study was to evaluate the efficacy of metamitron or metamitron plus benzyladenine as a post-bloom thinner on ?Baronesa? and ?Fuji? apples. Three experiments (rate, timing and BA combination) were conducted during two crop seasons, 2013/14 and 2014/15 at the experimental station located in Caçador, SC. Fruit set, fruit drop, yield per tree, fruit size and flowering return were assessed. The efficacy of metamitron was affected by time of application, and when applied at petal fall, promoted the proper adjustment of the production load of plants. Yield per plant reduces, whereas the allocation of fruits in categories of greater size increases proportionally to the increase in the metamitron concentration applied. However, there is... |
