Other claims from this paper (11)
- Intervention effect Low irrigation gave the greatest fraction of flowering trees and flowers per tree.
- Intervention effect Low irrigation gave the least height and diameter growth.
- Intervention effect Phosphorus fertilization did not affect flowering percentage or five year growth.
- Intervention effect Phosphorus fertilization slightly increased female flower number at age five.
- Association Flowering percentage increased with tree size within irrigation regimes.
- Observation Flowering varied substantially among families.
- Association Tree size and flowering traits had positive but low correlations.
- Association The irrigation effect on flowering differed among families at ages four and five.
- Observation By age six, more trees flowered and irrigation differences were reduced.
- Intervention effect Close spacing caused crown recession and mortality by age five.
- Recommendation Seed production spacing below 2 m was recommended only with roguing by age two to three.
