Wood Permeability in Eucalyptus grandis and Eucalyptus dunnii [PDF]

Floresta e Ambiente, 2017
The objective of this study was to evaluate the flow of air and water in Eucalyptus grandis and Eucalyptus dunnii wood. Wood was collected from four trees aged 37 years in an experimental plantation of the Federal University of Lavras, Brazil. Planks were cut off the basal logs to produce specimens for air and water permeability testing.

IRRIGAÇÃO NO DESENVOLVIMENTO INICIAL DE Eucalyptus urophylla x Eucalyptus grandis e Eucalyptus grandis x Eucalyptus camaldulensis

Ciência Florestal, 2017
The aim of this study was to evaluate the initial development of two hybrids of eucalypt (Grancam and Urograndis), microsprinkler and drip irrigated and non-irrigated from 7 to 17 months after planting (MAP). The experiment was installed in the area of irrigation and experimental demonstration of ‘Universidade Estadual de Mato Grosso do Sul’ in ...

Differences in wood properties among Eucalyptus grandis and Eucalyptus grandis x Eucalyptus urophylla with different degrees of ploidy

Research, Society and Development, 2021
We compared the anatomy, density, chemical contents, and bioenergy values of Eucalyptus grandis and hybrids of Eucalyptus grandis x Eucalyptus urophylla wood originating from diploids, triploids and tetraploids. We hypothesize that Eucalyptus grandis and hybrids of Eucalyptus grandis x Eucalyptus urophylla with different degrees of ploidy have ...

Proteome profiling of vascular sap regarding Eucalyptus grandis, Eucalyptus urophylla, and Eucalyptus camaldulensis

PROTEOMICS, 2023
AbstractThe plant vascular system is a key element for long‐distance communication. Understanding its composition may provide valuable information on how plants grow and develop themselves. In this study, a quantitative proteome dataset of the vascular sap proteome of three commercially important Eucalyptus species was shown.

Light quality in micropropagation of Eucalyptus grandis × Eucalyptus urophylla

Scientia Forestalis, 2020
The importance of eucalypts species and their interspecific hybrids has been evidenced in forestry programmes due to their wood quality and adaptation to diverse environmental conditions. To solve the limiting factors in the in vitro cultivation of the A211 clone of Eucalyptus grandis Hill ex Maiden × Eucalyptus urophylla S. T.

Tolerance of eucalypt (Eucalyptus spp.) seedlings to imazapyr in nutritive solution Tolerância de mudas de eucalipto (Eucalyptus spp.) ao imazapyr, em solução nutritiva

Planta Daninha, 2004
Imazapyr has presented excellent results in controlling coppices in stand reforms of eucalypt forests, despite differences in the efficacy levels. To find out whether these different responses are caused by the genetic variability of the cultivated ...

Seed viability constants for Eucalyptus grandis [PDF]

Pesquisa Agropecuária Brasileira, 2007
This work aimed to analyse Eucalyptus grandis W.Hill ex Maiden seed behaviour, under controlled deterioration, and to estimate viability equation constants for the species. Seeds were harvested in the growing season of 1999, and the moisture contents were adjusted from 11.3% to a range between 1.2 and 18.1% at 25ºC.
