Other claims from this paper (7)
- Intervention effect GA 4/7 applications promoted female flowering in lodgepole pine.
- Intervention effect Average number of female strobili increased 2- to 6-fold with growth regulator treatment compared with controls.
- Intervention effect Clonal or family frequency of flowering was higher in treated lodgepole pine than in controls, at 11 to 67%.
- Intervention effect Number of female strobili increased 2- to 14-fold with growth regulator treatment compared with controls within an experiment.
- Association Response in adjacent branches was positively correlated with increasing GA 4/7 dosage.
- Association Male flowering occurred significantly in only one experiment, with girdling and GA 4/7 treatment as promoting factors.
- Recommendation Spray applications of GA 4/7 + NAA are warranted to induce early and enhanced flowering in lodgepole pine for genetic improvement programs.
