| In Peach (Prunus persica) several physiological changes, such as woolliness, triggered by chilling injury are involved in major production losses due to cold storage of the fruits during shipping. Additionally, the low level of polymorphisms among peach varieties is an important limitation in the search for new molecular markers that could be associated with economically important traits. Therefore, a functional approach was employed to associate candidate genes with an informative marker in peach. The data was obtained from the results of an in silico analysis of four different cold peach treatments. Thirty two candidate genes were selected that were aligned against Arabidopsis thaliana genomic sequences to design intron-flanking EST-PCR markers. These... |

| RESUMO A morte precoce do pessegueiro é uma síndrome caracterizada por um colapso das plantas ao final do período de dormência, cujas causas envolvem diversos fatores bióticos e abióticos. Objetivou-se avaliar a associação da morte precoce do pessegueiro com à fertilidade do solo. Amostraram-se a rizosfera, para análise química, sob a copa de plantas sintomáticas e assintomáticas, com idade entre dois e oito anos, em nove pomares comerciais localizados nos municípios de Pelotas e Canguçu, no Rio Grande do Sul, totalizando 108 amostras. De acordo com os resultados, a obtenção de uma função discriminante para classificar as plantas em duas categorias, como sintomáticas ou assintomáticas, não proporcionou resultado satisfatório, pois a taxa de classificação... |

| Prunus persica has been proposed as a genomic model for deciduous trees and the Rosaceae family. Optimized protocols for RNA isolation are necessary to further advance studies in this model species such that functional genomics analyses may be performed. Here we present an optimized protocol to rapidly and efficiently purify high quality total RNA from peach fruits (Prunus persica). Isolating high-quality RNA from fruit tissue is often difficult due to large quantities of polysaccharides and polyphenolic compounds that accumulate in this tissue and co-purify with the RNA. Here we demonstrate that a modified version of the method used to isolate RNA from pine trees and the woody plant Cinnamomun tenuipilum is ideal for isolating high quality RNA from the... |

| The rapid identification of the hybrids between sweet cherry (Prunus avium L.) and sour cherry (Prunus cerasus L.) is not easy. In order to resolve this problem, 18 Spanish sweet, sour and duke cherry cultivars were surveyed and characterized using 43 agromorphological descriptors evaluated in flowers, leaves, dormant 1-yr-old shoots, fruits, and trees during 2005 and 2006. Based on quantitative parameters, ANOVA and stepwise discriminant analysis (SDA) were carried out. For qualitative descriptors, statistical comparisons were done by means of the chi-square (χ2) test. As result of the study, two quantitative (titratable acidity and number of lenticels) and six qualitative descriptors (shape of the central and lateral lobes in the internal bracts... |

| O pessegueiro é, geralmente, cultivado por causa dos frutos que produz. Entretanto, há os que se cultivam como plantas ornamentais e, inclusive, há programas de melhoramento de pessegueiros para esta finalidade. O objetivo deste trabalho foi avaliar os genótipos de pessegueiros ornamentais do programa de melhoramento da Embrapa Clima Temperado, quanto ao seu potencial para o uso no paisagismo. Foram observados o início, a plena e o final de floração, a tonalidade e o número de pétalas, o número de sépalas, a cor das folhas e quais genótipos produziram ou não frutos, no campo experimental da referida Instituição. Considerando os resultados obtidos e comparando-os com os observados para as cultivares já lançadas, 'Rosaflor' e 'Nectaflor', verificou-se que,... |

| O objetivo deste trabalho foi determinar os parâmetros biológicos e a tabela de vida de fertilidade da broca-do-morangueiro (Lobiopa insularis) criada em dieta artificial à base de frutos de morangueiro, em condições de laboratório. A duração e a viabilidade média dos períodos embrionário, larval, pupal e ovo-adulto foram de: 4,1±1,5 dias e 80,6%; 22,2±5,0 dias e 60%; 10,8±2,3 dias e 90%; e 37,1±8,8 dias e 43,5%, respectivamente. Os períodos de pré-oviposição, oviposição e pós-oviposição foram de 96±18,9, 133±27,5 e 77±16,3 dias. A longevidade de machos (271±20,7 dias) foi menor do que a de fêmeas (318±14,9 dias). Há potencial de utilização de dieta artificial à base de morangos para a multiplicação da broca-do-morangueiro em laboratório. |

| In southern Brazil, Grapholita molesta (Busck) (Lepidoptera: Tortricidae) uses diapause as survival strategy during the winter (May-August). In our study, we evaluated the effect of diapause on biological characteristics of the species for 4 months in laboratory. Newly hatched larvae of G. molesta were induced to diapause changing the photoperiod and temperature (T) (12 ± 1°C), relative humidity (RH) (70 ± 10%), and a photophase of 12 h and, when they started diapause in the prepupal stage, the conditions were kept for 4 months. Afterwards, the insects were induced to finalize the diapause process at T 25 ± 1°C, RH 70 ± 10%, and a photophase of 16 h. We... |

| Grapholita molesta (Busck) is one of the major pests of Rosaceae, causing significant damage to buds and fruits. In Southern Brazil, its population density is reduced during Rosaceae dormancy months. The present study evaluated the influence of different photoperiods (L:D) (10:14, 11:13, 12:12, 13:11, 14:10 and 16:8) at 25 ± 1ºC and 60 ± 10% RH on diapause induction of G. molesta eggs, larvae, prepupae, and pupae. The effects of the photoperiod on the life cycle of non-diapausing insects and on the second generation were also assessed. Prepupal diapause was observed only when eggs and neonates (< 12h-old larvae) were exposed to photophases from 10h to 14h long. Development of non-diapausing individuals and those from the second generation tended to be... |

| Para avaliar o potencial de enraizamento de estacas de ramos lenhosos e semilenhosos de cultivares de ameixeira (Carmesin, Gema de Ouro, Januária e Reubennel), utilizou-se aplicação exógena de ácido indolbutírico (IBA) em diferentes concentrações (0; 1000; 2000 e 3000mg L-1). O trabalho foi desenvolvido na Universidade Federal de Lavras (Lavras-MG), em 1997. Após os tratamentos, as estacas foram plantadas em areia lavada e colocadas em casa de sombreamento (lenhosas) e em casa de vegetação (semilenhosas) para enraizar. Foram avaliadas as variáveis porcentagem de enraizamento, número e comprimento de raízes. As maiores porcentagens de enraizamento foram obtidas com estacas semilenhosas da cultivar Januária (54,62%). A aplicação de IBA favoreceu o... |

| Abstract In contrast to ripening of climacteric fruits knowledge, non-climacteric fruits ripening still poorly understood. In this sense, strawberry (Fragaria x ananassa L. Duch) is a high commercial crop and has an expressive world production that has been used as a model study. Thus, the aim of this study was to evaluate the effect on physicochemical and phytochemical characteristics of strawberry Cv. Camiño Real, in four maturation stages (green, white, pink and red) after the ethylene (Etephon®) and brassinosteroid (epi-brassinolide) exogenous spray. The evaluations were carried out at application time (field assay) and after 24h (post-harvest assay). Brassinosteroid application tends to reduce phenolic compounds content mainly in the red stage,... |

| Systematic studies of angiosperm fossil woods from sediments of the Río Leona Formation were continued. A new morphospecies of Maloidoxylon with affinity to Rosaceae was described and constitutes, together with the fossil pollen from the same strata, the oldest South American fossil with this familial affinity. Nothofagaceae fossil woods are represented by the morphospecies Nothofagoxylon scalariforme Gothan, Nothofagoxylon kraeuseli Boureau et Salard, Nothofagoxylon triseriatum Torres et Lemoigne, Nothofagoxylon ruei Salard and a new morphospecies of Nothofagoxylon. Three of the four subgenera of Nothofagus were recognized in the fossil woods and a new infrageneric affinity for Nothofagoxylon ruei was proposed. The described woods have affinity to extant... |

| Abstract Several studies have been conducted in Brazil with rooting of plum scion cultivars, however, it is not known the performance and benefits of own-rooted trees at field. This study aimed to evaluate the leaf nutrient content (N, P, K, Ca, Mg, Fe, Mn, Zn, Cu and B) in seven Japanese plum cultivars (Prunus salicina) on the 2nd and 3rd year after field planting, whose nursery trees were produced by “T-inverted” budding method over ‘Capdeboscq’ peach (P. persica) or by own-rooted hardwood cuttings. The experimental design was in randomized blocks, factorial 7 x 2 (cultivars x nursery tree types), with five replicates of one tree per plot. We conclude that leaf nutrient content of Japanese plums varies among cultivars; however there is no cultivar that... |
