- Intervention effect Bud treatment with GA 4+7 increased shoot height of bitternut hickory by 234% compared with nontreated control plants.
- Intervention effect Bud treatment with GA 4+7 increased shoot height of pecan by 144% compared with nontreated control plants.
- Intervention effect GA 4+7 applied to seedlings of bitternut hickory shortly after germination increased shoot height and dry weight.
- Recommendation Plant growth regulators could be effective at increasing shoot extension of some hickories.
