Other claims from this paper (7)
- Observation Phenological and growth traits differed among hybrid clones and P. tremula.
- Observation The growth period was 143–158 days for hybrid clones versus 112 days for P. tremula.
- Observation Hybrid height grew 4.2 cm per 7 days in year three versus 2.4 for P. tremula.
- Observation Hybrid height grew 6.4 cm per 7 days in year four versus 2.9 for P. tremula.
- Observation After five years, mean estimated hybrid stem volume was 3.9 times that of P. tremula.
- Association Clone-by-year interaction was significant for height, diameter and volume growth.
- Mechanism The authors attribute hybrid vigor mainly to a longer growth period.
