13. Etiologia da mortalidade de miniestacas de Eucalyptus benthamii e possíveis fontes de inóculo
RESUMO Eucalyptus benthamii é originário da Austrália, cultivado na região Sul do Brasil, devido à sua tolerância ao clima frio. Durante a produção de mudas dessa espécie vários fatores bióticos e abióticos adversos têm surgido em viveiros. Dessa forma, o presente trabalho teve como objetivo avaliar a podridão de miniestacas de E. benthamii em

14. Advances in vegetative propagation of Olive tree
Resumo No Brasil é crescente o interesse pela cultura da oliveira, especialmente naquelas regiões consideradas aptas ao cultivo, onde se têm ocorrência de baixas temperaturas entre 8ºC e 10ºC no período que antecede a floração. As áreas com estas características estão localizadas, principalmente, nas regiões Sul e Sudeste do país, caracterizad

15. Cocoa propagation, technologies for production of seedlings
Resumo A propagação vegetativa em cacaueiro foi iniciada na América Central no início do século passado. No entanto, somente no final do século essa técnica foi intensificada no estado da Bahia onde se verificou que mudas de propagação vegetativa elevam o rendimento de áreas de cultivo do cacaueiro, especialmente aquelas que usam outras tecnologia

16. Advances in the spread of vegetative blueberry
Resumo A falta de método eficiente de propagação em algumas cultivares dificulta a expansão da cultura do mirtileiro. No Brasil ainda não se produz muda com qualidade e quantidades necessárias para alavancar o setor. A clonagem do material selecionado através de minipropagação e micropropagação é uma alternativa para aumentar a capacidade de mul

17. Avances en la propagación del aguacate
Abstract Being the avocado a highly cross-pollinated and heterozygous species, its multiplication from seeds produces a highly variable progeny in relation to the morphological and biological characteristics of the parents. Therefore, the adoption of more efficient propagation methods for obtaining higher quality seedlings in terms of production and disease

18. CARACTERIZACIÓN MORFOLÓGICA DE GERMOPLASMA DE GUAYABOS DE MÉXICO: IMPLICACIONES EN SU CONSERVACIÓN Y MEJORAMIENTO GENÉTICO
ABSTRACT Guavas (Psidium guajava L.) growing throughout Mexico show broad morphologic and productive variation due the crop is commonly sexual-propagated. The characterization of genetic diversity of Mexican guava germplasm will allow identify potential parents for genetic improvement as well as the production of new clonal cultivars. In this work 88 guava

19. Biofilm production by clinical isolates of Pseudomonas aeruginosa and structural changes in LasR protein of isolates non biofilm-producing
ABSTRACT Introduction: Biofilm production is an important mechanism for the survival of Pseudomonas aeruginosa and its relationship with antimicrobial resistance represents a challenge for patient therapeutics. P. aeruginosa is an opportunistic pathogen frequently associated to nosocomial infections, especially in imunocompromised hosts. Objectives: Analyz

20. Thinning regimes and initial spacing for Eucalyptus plantations in Brazil
ABSTRACT This study focuses on the effects of different thinning regimes on clonal Eucalyptus plantations growth. Four different trials, planted in 1999 and located in Bahia and Espírito Santo States, were used. Aside from thinning, initial planting density, and post thinning fertilization application were also evaluated. Before canopy closure, and therefor

21. Clonal relationships, antimicrobial susceptibilities, and molecular characterization of extended-spectrum beta-lactamase-producing Escherichia coli isolates from urinary tract infections and fecal samples in Southeast Iran
Abstract INTRODUCTION: Multidrug-resistant (MDR) Escherichia coli, a species that is a leading cause of urinary tract infections (UTIs) and is a major global public health concern. This study was designed to detect the differences in antibiotic resistance patterns, the production and type of extended spectrum β-lactamases (ESBLs), and the clonal relationsh

22. Clonal relation and antimicrobial resistance pattern of extended-spectrum β-lactamase- and AmpC β-lactamase-producing Enterobacter spp. isolated from different clinical samples in Tehran, Iran
Abstract INTRODUCTION: Here, we determined the genes encoding antibiotic resistance enzymes and virulence factors and evaluated the genetic relationship between Enterobacter spp. isolated from different clinical samples. METHODS: A total of 57 clinical isolates of Enterobacter spp. were tested for the production of extended-spectrum β-lactamases (ESBLs)

23. Mini-incubators improve the adventitious rooting performance of Corymbia and Eucalyptus microcuttings according to the environment in which they are conditioned
ABSTRACT We addressed a major challenge in the in vitro clonal propagation of Corymbia citriodora, Eucalyptus urophylla and E. benthamii by using an ex vitro adventitious rooting strategy in a mini-incubator. Mini-incubators were placed in four environments for rooting. A shade house with no fogging system and a greenhouse with no ventilation but with a fogg

24. Gene transfer utilizing pollen-tubes of Albuca nelsonii and Tulbaghia violacea
Abstract Developing a tissue culture-independent genetic transformation system would be an interesting technique for gene transfer in valuable medicinal and horticultural plants. Efficient gene delivery (Agrobacterium tumefaciens strain LBA 4404: harbouring PBI121 plasmid) was achieved with Km-resistant pollen grains (pollen tube technique) and were found to
