Other claims from this paper (12)
- Observation The two species differed in seed behavior and seed and fruit types.
- Observation C. ferrea seed coats had two osteosclereid layers, macrosclereids and fibres.
- Observation C. echinata seed coats had only macrosclereids and fibres.
- Observation Developing C. echinata seed coats had paracytic stomata.
- Mechanism Seed coat features may account for low C. echinata seed longevity.
- Observation Embryo growth relative to seed growth did not differ between species.
- Observation Seeds of both species behaved as typical endospermic seeds.
- Association C. ferrea embryo growth accelerated as pericarp sclerenchyma developed.
- Association C. echinata embryo growth coincided with completion of pericarp spine and secretory reservoir development.
- Observation Both species had a mucilage-secreting endothelial layer.
- Observation C. ferrea had a nucellar summit growing into the micropyle.
- Observation C. ferrea had a placental obturator connecting ovarian tissue to ovule.
