Variations and heredity of paper pulpwood properties of new Aigeiros clones of southern type |
|
| Abstract: | A systematic study made in Linhai on wood properties of paperpulpwood of 17 new clones and other 3 clones as a control shows that the fiber length in the trunk of these 20 clones ranges between 0.966 0 and 1.143 0 mm，which has met the standard laid down by the International Timber Society for the fiber of middle rank and the specific gravity of the trunk is from 0.318 8 to 0.368 2 g.cm－3；that the fiber length of branches ranges from 0.63 to 0.78 mm and their specific gravity is from 0.344 2 to 0.400 8 g.cm－3；that each clone differs from the other in timber properties either significantly or most significantly；and that both fiber length and specific gravity have a relatively high genetic repetition（0.473 7～0.833 3)．Genetically speaking，DBH is moderately in negative correlation between timber properties．Such 4 clones among 17 new clones as 367，366，370 and 351 are very prominent in growth and wood properties，their growth and wood properties being superior to those of Populus deltoides cv． ‘Lux’ that is best in pulping at present．Therefore，these four clones are a top choice for establishing a short-rotation forest armed at producing paper pulpwood and fiber wood． |
