Other claims from this paper (19)
- Intervention effect Cottonwood leaf beetle defoliation decreased annual growth during the first three years.
- Observation Protected clones differed in specific gravity and density.
- Observation Specific gravity and density remained constant across the radius regardless of beetle attack.
- Intervention effect Defoliation did not affect fiber length.
- Intervention effect Defoliation changed vessel number and diameter, with offsetting effects on vessel area.
- Observation Ray area was larger in unprotected trees.
- Intervention effect One clone produced more rays after defoliation.
- Intervention effect The other clone produced fewer, larger rays after defoliation.
- Observation The two families did not differ in growth rate at the stressful site.
- Association Family and clone significantly influenced specific gravity.
- Association Clone and radial position affected fiber length, which correlated with growth rate.
- Observation Clonal mean fiber length differed nearer the bark.
- Recommendation The authors suggest selecting for fiber length only after four or five years.
- Observation Trees differed significantly in fiber length and vessel area.
- Observation Trees did not differ in vessel numbers, vessel diameter or ray numbers.
- Association Cambium age significantly affected all wood properties.
- Observation The fastest growing high gravity tree had the longest fibers and most rays.
- Observation The fastest growing high gravity tree had low vessel area, number and diameter.
- Association Trees of similar growth rate varied widely in vessel area.
