Other claims from this paper (8)
- Observation Usually three of four ovules in each Cryptantha flava ovary fail to develop, despite possible fertilization.
- Intervention effect Seeds from experimental ovule destruction had less emergence than control seeds.
- Intervention effect Overall survival from planting was greater for controls in both years.
- Intervention effect Plant height did not differ between ovule-destruction treatments in either year.
- Intervention effect Leaves per plant did not differ between ovule-destruction treatments in either year.
- Association Success measures differed significantly among sites.
- Association Some success measures showed significant treatment-by-site interactions.
- Mechanism The results support selective maturation of higher-quality embryos, with alternative explanations acknowledged.
