Other claims from this paper (11)
- Intervention effect GA increased IAA level and synthesis in isolated dwarf bean leaves.
- Intervention effect GA pretreatment increased rooting of detached leaf petioles.
- Intervention effect Adding tryptophane with GA particularly increased petiole rooting.
- Mechanism The authors attribute enhanced GA-induced rooting to increased IAA level in the lamina.
- Mechanism GA promotes use of tryptophane released from proteins in IAA biosynthesis.
- Mechanism The authors suggest TIBA suppresses rooting by inhibiting IAA transport into the petiole.
- Intervention effect Cytokinin pretreatment prevented root production.
- Mechanism Cytokinins retard protein decomposition, leaving less TPP for auxin synthesis.
- Intervention effect Cytokinin treatment increased cytokinin concentration in leaf tissue.
- Intervention effect Cytokinin pretreatment caused callus formation at petiole bases.
- Intervention effect Cytokinin pretreatment prevented root primordium differentiation.
