Other claims from this paper (12)
- Intervention effect P-IAA produced 95 to 154% more visible bean root primordia than IAA after two days.
- Intervention effect 3HP-IAA gave smaller increases in bean root primordia.
- Intervention effect 3HP-IAA was at least ten times as efficient as IAA for bean root initiation.
- Intervention effect Methyl indole-3-acetate was no more effective than IAA in bean tests.
- Intervention effect P-IBA increased rooted jack pine cuttings by 11 to 12% over a higher IBA concentration.
- Intervention effect P-IAA increased elongated bean roots by 165 to 276% after five days.
- Intervention effect 3HP-IAA caused smaller increases in elongated bean roots.
- Intervention effect P-IBA did not alter root number or longest root length per rooted jack pine cutting.
- Observation Bean and jack pine cutting enzymes hydrolyzed aryl esters.
- Mechanism Initial ester integrity was needed for enhanced root primordium initiation.
- Intervention effect P-IAA hydrolysates did not differ from IAA alone for bean root primordia.
- Intervention effect IAA and phenol did not differ from IAA alone for bean root primordia.
