Other claims from this paper (6)
- Intervention effect EGTA altered synchronized primary leaf movement.
- Association The EGTA effect depended on application phase.
- Intervention effect EGTA applied 8 h after lights-on advanced upward leaf movement by 3-6 h.
- Intervention effect EGTA applied in the middle of the night suppressed circadian rhythmicity.
- Intervention effect EGTA applied in the middle of the night promoted an ultradian rhythm.
- Observation The ultradian rhythm period was longer in light than darkness.
