Other claims from this paper (5)
- Observation Height and stem diameter growth discontinuities are asynchronous in Pinus radiata.
- Observation Where visible externally, the less clear height-growth discontinuity typically occurs in summer.
- Mechanism Substantial autumn height growth can produce a major discordance between annual height and diameter stages.
- Mechanism Discordant growth stages can confuse stem analysis and bias stem volume increment estimates.
- Association Moisture, fertility, temperature, latitude, genotype, stage, shoot vigour, and size can influence the discordance.
