Cryo-scanning electron microscopy images showing abnormal ovule development in Capsicum annuum genotypes. A-F, Abnormalities detected in the three genotypes were excessive integument growth (A), or carpelloid proliferation of integuments and or the incomplete coverage of the nucellus (B), integuments failing to cover the nucellus (C). In some, ovule structures the integuments partially recurved (D) or were absent (E). Some ovule primordia lacked chalaza and nucellus specification (F). Bar = 100 μm. Genotypes Orlando, Bruinsma Wonder and Line 3 grown at 20/18°C D/N were used for observation.
