Other claims from this paper (18)
- Observation Excised soybean leaf discs remained green after corresponding intact leaves yellowed.
- Observation Podded explants yellowed and abscised faster than intact plants.
- Observation Leaves of late-podfill podded explants began yellowing after 6 days.
- Observation Stomatal resistance increased after the first light period to above intact-leaf levels.
- Observation Pod load did not affect the time lag to leaf yellowing in mid- to late-podfill explants.
- Intervention effect Removing pods delayed explant leaf yellowing and abscission.
- Intervention effect Removing seeds delayed explant leaf yellowing and abscission.
- Intervention effect Complete mineral nutrient solution delayed explant leaf yellowing and abscission.
- Intervention effect Zeatin delayed explant leaf yellowing and abscission.
- Observation Protein loss accelerated in explants.
- Intervention effect Minerals retarded protein loss in explants.
- Intervention effect Zeatin retarded protein loss in explants.
- Observation Pod color-change patterns on explants resembled those on intact plants.
- Observation Pod color changes began earlier in explants on water than intact plants.
- Intervention effect Zeatin delayed pod color changes.
- Observation Seed dry weight increased in explants almost as much as in intact plants.
- Mechanism Authors infer root-derived minerals and cytokinin could affect soybean foliar senescence.
- Mechanism Authors infer increased stomatal resistance does not cause foliar senescence.
