摘要:
Embryo, ovule, and ovary development were studied inLimonium perigrinum(Bergius) following self‐ and cross‐pollinations. Four types of ovule were identified on the basis of their growth patterns and distinct morphological features. Fifty‐six percent of the cross‐pollinated florets but only 18% of the self‐pollinated florets produced embryos that developed normally. Forty‐four percent of the self‐pollinated florets produced embryos that ceased development at the globular to heart stage of development (within 18 days of pollination), whereas only 6% of the cross‐pollinated embryos ceased development at a similar stage. A similar proportion of self‐ and cross‐pollinated florets (36%) failed to develop embryos.
