Abstract:

We aimed to assess the quality of charcoal from three Eucalyptus and Corymbia citriodora species for energy production in the South of Tocantins state. A hybrid Eucalyptus urophylla x Eucalyptus grandis, the species Eucalyptus urophylla, Eucalyptus camaldulensis, and Corymbia citriodora were selected for the study. In the preparation of the material, 20 specimens of each species with the dimensions of 2.0 x 2.0 x 5.0 cm were made, being ten repetitions for each carbonization gait with different final temperatures and heating rates.

Abstract:

Abstract Eucalyptus is planted worldwide for raw material in paper and rayon industry. It is a potential out-crosser and the natural populations are highly heterogeneous displaying strong inbreeding depression. Eucalyptus hybrids have been intensively utilized for their vigor, higher wood quality and resistance to diseases. Identification of species for hybridization is predominantly based on morphological characters and is not always reliable. Hence, DNA marker based species identification and hybrid validation is an important and efficient tool in breeding programs. In the present study, att

Abstract:

The white grub of Exopholis hypoleuca (Wiedemann, 1819) (Coleoptera: Scarabaeidae: Melolonthinae: Leucopholini) is a known pest of several crops on Pacific Islands. This insect was observed feeding on the roots and shoots of Corymbia citriodora (Hook.) K.D. Hill & L.A.S. Johnson and Eucalyptus L'Hér. (Myrtaceae) plants in Aek Nauli, North Sumatra, Indonesia, which triggered its study. Management strategies of white grub are necessary to be developed because C. citriodora and Eucalyptus are largely planted in Indonesia for production of paper, pulp and viscose materials.
