Evidence for Selective Embryo Abortion in Cryptantha flava

Brenda B. Casper The American Naturalist 1988. doi:10.1086/284855

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.

Intervention effect Regular subculture every 30-40 days promoted plant height and secondary roots.
Intervention effect Two irrigation techniques decreased culture contamination.
Intervention effect PEG reduced secondary roots, expanded leaves, plant height and leaf production.
Intervention effect PVP reduced secondary roots, expanded leaves, plant height and leaf production.
Intervention effect Plastic tent acclimatization gave higher seedling survival than T misting.
Intervention effect Wooden box humidity chamber acclimatization gave higher seedling survival than T misting.
