POSTPOLLINATION FLORAL BIOLOGY OF LIMONIUM-PERIGRINUM (BERGIUS)

Embryo, ovule, and ovary development were studied in Limonium perigrin um (Bergius) following self- and cross-pollinations. Four types of ovu le were identified on the basis of their growth patterns and distinct morphological features. Fifty-six percent of the cross-pollinated flor ets 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 stag e of development (within 18 days of pollination), whereas only 6% of t he cross-pollinated embryos ceased development at a similar stage. A s imilar proportion of self- and cross-pollinated florets (36%) failed t o develop embryos.
