Other claims from this paper (13)
- Intervention effect IBA enhanced rooting in plum cuttings with one-half or three leaves.
- Observation Leafless plum cuttings failed to root regardless of treatment.
- Observation Most radiocarbon remained in the upper stem adjacent to the treated leaf.
- Observation The mid-stem acquired about 40% of the radiocarbon activity.
- Observation Little radiocarbon reached the base of fresh cuttings.
- Association Rooted bases accumulated four times the percentage of radiocarbon found in nonrooting bases.
- Observation Radiocarbon incorporation into starch was much greater in mid-stem than in the base.
- Observation Up to 75% of radioactivity in rooted bases was in residue left after ethanol solubles and starch were removed.
- Observation Starch declined continually in cutting bases.
- Observation Mid-stem starch decreased only at the end of the study.
- Observation Sorbitol concentration declined markedly and was hardly detectable in rooted bases.
- Observation The largest carbohydrate loss occurred in bases treated with IBA.
- Mechanism Carbohydrate utilization in bases was similar with and without leaves, suggesting leaves stimulate rooting without serving as a carbohydrate source.
