Other claims from this paper (14)
- Observation Petiole expansion was faster than blade expansion.
- Observation Lateral expansion exceeded longitudinal expansion at days 5 to 10.
- Observation Lateral and longitudinal blade expansion later became equal.
- Observation Anticlinal expansion co-occurred with periclinal expansion but was an order of magnitude slower.
- Observation Anticlinal expansion was highest in spongy mesophyll and lowest in epidermis.
- Observation Epidermal cell division was faster and lasted longer than palisade mesophyll division.
- Intervention effect Low light reduced leaf expansion rates.
- Intervention effect Low light lengthened the growth phase, partly compensating for lower expansion rates.
- Intervention effect Shading enhanced petiole expansion rates.
- Intervention effect Shading reduced blade-to-petiole ratio by 50%.
- Intervention effect Low light reduced leaf thickness through inhibition of anticlinal expansion.
- Intervention effect Low light inhibited anticlinal cell expansion rates.
- Intervention effect The cell division response preceded expansion and led to one fewer palisade layer.
- Intervention effect Contrasting light shifts after germination uncoupled division and expansion effects.
