Claim · model-written summary
The water control treatment gave the highest percent of acceptable (Grades 1 and 2) rooted cuttings, 75%, because it also had the highest rooting percent.

Other claims from this paper (12)
- Intervention effect Full-sib family, rooting compound concentration and their interaction significantly affected percent rooted and other traits of loblolly pine cuttings.
- Intervention effect Boron and thiamine main effects were not significant for percent rooted or other traits of loblolly pine cuttings.
- Intervention effect Cuttings receiving 9% rooting compound rooted at 64%, lower than the 75% of the water control.
- Intervention effect Cuttings receiving 17% rooting compound rooted at 55%, lower than the 75% of the water control.
- Intervention effect Root systems of cuttings receiving rooting compound treatments were more symmetrical, more vertically oriented and had greater dry weights than those of the water control.
- Intervention effect Basal stem caliper, shoot dry weight and root:shoot ratio were greater for cuttings receiving the rooting compound treatments.
- Observation When seedling caliper standards were used for grading, no rooted cuttings were culled.
- Observation Yield of acceptable rooted cuttings for the five full-sib families receiving the water control ranged from 58 to 84%.
- Intervention effect With additional root system standards imposed on the caliper grades, the 9% rooting compound concentration gave the highest percent of acceptable rooted cuttings, 53%.
- Observation Acceptable yields of the five full-sib families receiving the 9% rooting compound ranged from 35 to 79% under the additional root system grading standards.
- Observation Rooted cuttings produced by directly setting cuttings in open nursery beds exceeded commonly used seedling grading standards.
- Recommendation The authors suggest an economical system of rooting loblolly pine cuttings in open nursery beds may be feasible.
