Claim · model-written summary
The authors suggest the proportion of seedlings with a 2-year-old shoot morphology after one growing season in a heated greenhouse may serve as an early test for height growth potential in seed origins and possibly progenies.

Other claims from this paper (7)
- Observation Two types of shoot morphology were observed in Scots pine seedlings of a single seed source raised for 26 weeks in a heated greenhouse.
- Association Compared with type 1 plants, type 2 plants had an earlier start to shoot elongation, set buds earlier and stopped shoot elongation sooner.
- Association After one growing season, type 2 plants were shorter than type 1 plants.
- Association After one growing season, type 2 plants had fewer stem units for shoot elongation in the second season than type 1 plants.
- Association After one growing season, type 2 plants carried a greater foliage biomass than type 1 plants.
- Association After two seasons type 2 plants remained shorter.
- Recommendation The authors conclude that rearing practices producing seedlings with this type 2 shoot morphology are undesirable.
