Genetic diversity in wild and breeding populations and clones of Eucalyptus urophylla and Eucalyptus grandis

Silvae Genetica
Brazil has a long history of intensive silviculture with Eucalyptus species, mainly Eucalyptus urophylla and E. grandis. However, breeding advances may reduce genetic diversity in bred populations.

Comparative microsporogenesis and flower development in Eucalyptus urophylla × E. grandis

Journal of Forestry Research, 2015
Microsporogenesis and flower development in Eucalyptus urophylla × E. grandis were examined using chromosome tableting to provide a method to predict the meiotic stages in this species. Although microsporogenesis was normal, cytokinesis during meiosis of pollen mother cells occurred simultaneously, with strong asynchronism observed in the two different

Plant regeneration from seedling explants of Eucalyptus grandis × E. urophylla

Plant Cell, Tissue and Organ Culture, 1999
Hypocotyls, cotyledons, cotyledonary nodes and primary leaves were used as explants to establish a regeneration protocol for Eucalyptus grandis × E. urophylla. These seedling-derived explants were incubated on a modified MS medium (SP medium), supplemented with 2.0 μM TDZ.

Agrobacterium strain specificity and shooty tumour formation in eucalypt (Eucalyptus grandis ×E. urophylla)

Plant Cell Reports, 1997
To develop a successful protocol forAgrobacterium-mediated transformation in plants it is essential to determine the most efficient bacterial strain/plant genotype interaction. In the present work, we evaluated the susceptibility ofEucalyptus grandis ×E. urophylla to fiveAgrobacterium rhizogenes and twelveA. tumefaciens wildtype strains.

Effects of steaming treatment on crystallinity and glass transition temperature of Eucalyptuses grandis×E. urophylla

Results in Physics, 2017
To investigate the effects of steaming treatment on crystallinity and glass transition temperature, samples of Eucalyptuses grandis × E. urophylla with moisture content of 50%, 70%, and 90% were steamed in saturated steam at 100 °C for 2, 4, 6, and 8 h.

Selecting for stable and productive families of Eucalyptus urophylla across a country-wide range of climates in Brazil

Canadian Journal of Forest Research, 2019
To identify stable and productive Eucalyptus urophylla S.T. Blake families across diverse climate zones in Brazil, we evaluated growth and survival of 322 open-pollinated families derived from 13 genetically improved seed sources in 10 trials across the ...
