Other claims from this paper (13)
- Observation Germination of Nymphaea seeds was generally below 10% after 28 d in control treatments.
- Intervention effect Germination percentage of Nymphaea seeds was highest at 30 or 35 °C for seeds exposed to light and treated with ethylene or in anoxic conditions.
- Observation Germination percentage differed significantly between collections of N. macrosperma.
- Observation Germination percentage differed significantly between collections of N. violacea.
- Observation Seeds of N. pubescens did not germinate under any of the conditions.
- Observation Embryo growth of 8-37% in length occurred before hypocotyl emergence in seeds of the five Nymphaea species that germinated.
- Observation Fresh Nymphaea seeds were dormant.
- Observation Pregermination embryo growth in seeds of N. lukei and N. immutabilis was relatively small.
- Observation Pregermination embryo growth in seeds of N. macrosperma, N. ondinea and N. violacea was relatively large.
- Observation Seeds of N. lukei and N. immutabilis were concluded to have physiological dormancy (PD).
- Observation Seeds of N. macrosperma, N. ondinea and N. violacea were concluded to have morphophysiological dormancy (MPD).
- Observation Seeds in the most phylogenetically derived clades within Nymphaea have MPD.
- Observation The authors suggest that physiological dormancy is the most likely basal trait within the Nymphaeales.
