Fecha de publicación: | nov-1991 | Editor: | Ejnar Munksgaard | Citación: | Physiologia Plantarum 83/3: 411-416 (1991) | Resumen: | The histological development of fertilized ovules during fruit-set and development in pea (Pisum sativum L. cv. Alaska) has been investigated. Killing the ovules on day 0 (anthesis) or day 1 prevented fruit-set and resulted in ovary degeneration. When the ovules were destroyed at later stages the ovaries developed, though the rate of growth of the pod was reduced significantly. Pollination in pea occurs normally the day before anthesis, and fertilization of the egg cell 32 to 48 h later. The first divisions of the zygote and endosperm nuclei started simultaneously (ca 48 h after pollination) but the endosperm developed more rapidly than the embryo; the embryo sac cavity was lined with free endosperm nuclei at the time of beginning suspensor elongation. Extracts of endosperm and ovule coats from ovules at day 7 after anthesis showed fruit-set activity in pea, the latter material having about 3 times more activity than the former per ovule basis. These results indicate that fertilization of the ovule is necessary for fruit-set in pea, and that compounds which induce fruit-set are probably synthesized in the ovules following fertilization. | Versión del editor: | http://dx.doi 10.1034/j.1399-3054.1991.830312.x | URI: | http://hdl.handle.net/10261/75970 | ISSN: | 0031-9317 |
