Other claims from this paper (17)
- Observation Excised soybean explants senesced sooner than intact structures.
- Observation Pod development was advanced in soybean explants.
- Observation Seed yield was reduced in soybean explants.
- Intervention effect Cytokinin retarded leaf yellowing and blade and petiole abscission.
- Intervention effect Cytokinin retarded soybean pod development to a lesser extent.
- Intervention effect At 3×10−7m, diZR delayed soybean leaf yellowing by 18 days.
- Intervention effect At 3×10−7m, benzyladenine delayed soybean leaf yellowing by 15 days.
- Intervention effect At 3×10−7m, diZ delayed soybean leaf yellowing by 12 days.
- Intervention effect At 3×10−7m, ZR delayed soybean leaf yellowing by 4–6 days.
- Intervention effect At 3×10−7m, zeatin delayed soybean leaf yellowing by 2–5 days.
- Intervention effect At 3×10−7m, isopentenyladenine delayed soybean leaf yellowing by 2 days.
- Observation Cytokinins showed a similar activity hierarchy for abscission.
- Intervention effect Cytokinin retarded changes in soybean stomatal resistance and transpiration rate.
- Observation Cytokinin activity rankings for stomatal resistance and pod development differed from leaf yellowing rankings.
- Intervention effect A three-day cytokinin pulse produced a different activity pattern from continuous supply.
- Mechanism The authors infer that root-derived xylem cytokinins help maintain soybean foliage.
- Mechanism The authors infer that reduced root cytokinin supply may contribute to monocarpic soybean senescence.
