1. Identification of the Er1 resistence gene and RNase S-alleles in Malus prunifolia var. ringo rootstock
Woolly apple aphid (WAA; Eriosoma lanigerum Hausm.) is a major insect pest that has significant economic impact on apple growers worldwide. Modern breeding technologies rely on several molecular tools to help breeders select genetic determinants for traits of interest. Consequently, there is a need for specific markers linked to the genes of interest. Apple

2. Resgate de embriões a partir de cruzamentos interespecíficos em porta-enxerto de macieira
O objetivo deste trabalho foi resgatar embriões imaturos de porta-enxertos de macieira Malus prunifolia (Marubakaido) e Malus pumila (M9) depois de 40 e 60 dias de polinização e colocá-los em meio de cultura MS suplementado com ágar (6 g L-1) e hidrolisado de caseína (500 mg L-1). Embriões originados do cruzamento interespecífico dirigido e de polini

3. EFEITO DA POLINIZAÇÃO DIRIGIDA ENTRE PORTA-ENXERTOS DE MACIEIRA (Malus sp.) NA FRUTIFICAÇÃO EFETIVA E NO DESENVOLVIMENTO DE FRUTOS EM SÃO JOAQUIM-SC
Com o objetivo específico de obter uma população segregante, visando à avaliação na frutificação efetiva, quantidade de sementes normais e peso e diâmetro de frutos oriundos de polinização aberta e dirigida, foram realizados cruzamentos entre dois porta-enxertos de macieira, Marubakaido (Malus prunifolia Borkh.) e M.9 (Malus pumila Mill.) na Esta�

4. ENRAIZAMENTO EX VITRO E ACLIMATIZAÇÃO DO PORTA-ENXERTO DE MACIEIRA M.9
A micropropagação pode ser utilizada para a produção deste porta-enxerto; no entanto, o enraizamento e a aclimatização são pontos de estrangulamento para o uso comercial desta tecnologia. O presente trabalho foi conduzido com o objetivo de avaliar diferentes níveis de ácido indolbutírico (AIB) no enraizamento ex vitro e aclimatização simultânea

5. Relationship between Indole-3-Acetic Acid Levels in Apple (Malus pumila Mill) Rootstocks Cultured in Vitro and Adventitious Root Formation in the Presence of Indole-3-Butyric Acid 1
In vitro rooting response and indole-3-acetic acid (IAA) levels were examined in two genetically related dwarfing apple (Malus pumila Mill) rootstocks. M.26 and M.9 were cultured in vitro using Linsmaier-Skoog medium supplemented with benzyladenine (BA), indole-3-butyric acid (IBA), and 1,3,5-trihydroxybenzoic acid (PG). Rooting response was tested in Lepoiv

6. Visualization of plant cell walls by atomic force microscopy.
Atomic force microscopy has been used to visualize the ultrastructure of hydrated plant cell wall material from prepared apple (Malus pumila MILL; Cox orange pippin), water chestnut (Eleocharis dulcis L.), potato (Solanum tuberosum L.; Bintje), and carrot (Daucus carota L.; Amsterdamse bak) parenchyma. Samples of cell wall material in aqueous suspension were

7. Rapid Increase in Deep Supercooling of Xylem Parenchyma 1
Malus pumila Mill. twigs were collected from September through December and stored at 5°C until the low temperature exotherms of the xylem were determined by differential thermal analysis. During the differential thermal analysis, cooling was interrupted, and temperatures of 5 to −18°C were held for 0.4 to 10 hours before cooling to −50°C was resumed.

8. Effects of Carbon Dioxide on Activity of Apple Mitochondria
Effects of CO2 on mitochondrial activity of apple (Malus pumila Mill. var. Richared Delicious) were studied in two ways. Immediate effects were determined by imposing 3 to 18% CO2-bicarbonate mixtures on isolated apple mitochondria, and long term effects were determined by extracting mitochondria from apples that had been stored for intervals in atmospheres

9. Units of Freezing of Deep Supercooled Water in Woody Xylem 1
The low temperature exotherms (LTE) of 1-year-old twigs of Haralson apple (Malus pumila Mill.), shagbark hickory (Carya ovata [Mill.] K. Koch), green ash (Fraxinus pennsylvanica Marsh), honey locust (Gleditsia triacanthos L.), American chestnut (Castanea dentata [Marsh] Borkh.), and red oak (Quercus rubra L.) were determined by differential thermal analysis

10. Selective maintenance of allozyme differences among sympatric host races of the apple maggot fly
Whether phytophagous insects can speciate in sympatry when they shift and adapt to new host plants is a controversial question. One essential requirement for sympatric speciation is that disruptive selection outweighs gene flow between insect populations using different host plants. Empirical support for host-related selection (i.e., fitness trade-offs) is s

11. Cloning, Expression, and Characterization of Sorbitol Transporters from Developing Sour Cherry Fruit and Leaf Sink Tissues1
The acyclic polyol sorbitol is a primary photosynthetic product and the principal photosynthetic transport substance in many economically important members of the family Rosaceace (e.g. almond [Prunus dulcis (P. Mill.) D.A. Webber], apple [Malus pumila P. Mill.], cherry [Prunus spp.], peach [Prunus persica L. Batsch], and pear [Pyrus communis]). To understan
