Other claims from this paper (12)
- Observation Intact mature dry seeds did not germinate under a wide variety of conditions.
- Intervention effect Opening or removing the testa made germination possible.
- Observation No inhibitors were found in the testa.
- Intervention effect Continuous light below 25 C inhibited germination of decoated seeds.
- Intervention effect Removing the inner seed membrane removed light inhibition of germination.
- Intervention effect Continuous light greatly reduced naked embryo growth at all temperatures and strongly influenced early development.
- Intervention effect The intact inner seed membrane inhibited germination in light below 25 C but had no effect in darkness.
- Mechanism Moist filter paper reproduced the membrane inhibitory effect, suggesting interference with respiratory gas exchange.
- Intervention effect Very low light intensities inhibited decoated seeds.
- Observation At least 12‐hr daily illumination was required for significant inhibition.
- Intervention effect Blue visible light was most inhibitory.
- Observation Light perception was located in the radicular embryo portions.
