Both of straight and inclining poplar clone 107 tree were selected for studying materials in this paper.The optimal pulping conditions was established by orthogonal experimental design both for normal wood and tension...
The absorption and enrichment of heavy metal elements by leaves of Populus×euramericana cv.’Neva’ were analyzed through content assessing of heavy metal elements in soils of three forest lands at Fangshan District ...
To investigate differences in physiological characteristics of growth and physiological basis of high growth vigor in the first generation of Populus deltoides which are from different growth vigor clones,here we chos...
Compared with the species of Leuce section,the difficulty in plant regeneration during tissue culture for the species of Aigeiros section is a key limiting factor for their application in genetic engineering of forest...
In order to select a suitable genotype for the studies on genetic transformation, the difference among three genotypes (DN04-18, DN04-25 and DN04-26) of Populus × euramericana (Populus deltoides × P. nigra) in terms...
Impregnation method can effectively improve physical and mechanical properties of wood. In this study, plantation poplar lumbers are impregnated by a low molecular weight phenol-formaldehyde resin solution with concen...

The visible and near infrared(NIR)(350-2500 nm)spectra and the MOE of 438 small clear wood samples from Chinese fir,eucalyptus and poplar 72 were measured.Using partial least-square(PLS)modeling,the NIR spectra could ...
Twenty-five new clones belong to Populus Aigeiros of both domestic and foreign origin hadbeen introduced and tested at nursery stage in Shandong province. Results showed that height (H),diameter at stem base (D0) and ...
