Quantitative Data on Petunia Embryogenesis: Mitotic Activity and Characteristics of the Cell Cycles
1988
The studies on the embryonal development of Angiosperms are essentially descriptive and some quantitative data are only available at the present time. Within Dicotyledons, one must mentioned the works of Rietsema and al. (1955) on the growth of ovules and embryos of Datura stramonium, the interesting comparison between the growth of Capsella and Gossypium embryos effected by Pollock and Jensen (1964), the studies of Simoncioli (1974) and Tykarska (1980) on two Brassicaceae, respectively Diplotaxis erucoides and Brassica napus, and the work of Gray and al. (1984) on the embryo development of Daucus carota.
Trophic relationships between the parasitic plant species phelipanche ramosa (L.) and different hosts depending on host phenological stage and host g…

Prod 2018-285c INRA AGROSUP GESTAD SPE CT3 SPE CT1 EJ2 EA; International audience; Phelipanche ramosa (L.) Pomel (branched broomrape) is a holoparasitic plant that reproduces on crops and also on weeds, which contributes to increase the parasite seed bank in fields. This parasite extracts all its nutrients at the host’s expense so that host–parasite trophic relationships are crucial to determine host and parasite growth. This study quantified the intensity with which P. ramosa draws assimilates from its host and analyzed whether it varied with host species, host phenological stage and host growth rate. A greenhouse experiment was conducted on three host species: the crop species Brassica na…
