متن کاملThe ultrastructure and ontogeny of pollen in Helleborus foetidus L. IV. Pollen grain maturation.
The final stages of Helleborus pollen-grain ontogeny, which culminate in maturation and germination of the grain, have been investigated at the ultrastructural level. Following the deposition of primary and secondary exine, and during the early stages of intine formation, the microspore passes through a vacuolate phase, in which the cytoplasm appears devoid of most organelles other than the pro...
متن کاملPlant traits, environmental factors, and pollinator visitation in winter-flowering Helleborus foetidus (Ranunculaceae).
BACKGROUND AND AIMS This study examined the effect of plant traits and environmental factors on pollinator visitation in the winter-flowering Helleborus foetidus (Ranunculaceae) in three distant regions in the Iberian Peninsula. METHODS Geographical variation in floral visitor assemblage, plant traits and environmental factors were analysed during the flowering season. KEY RESULTS Differenc...
متن کاملCytokinins in the perianth, carpels, and developing fruit of Helleborus niger L.
Reproductive development in the Christmas rose (Helleborus niger L.) differs from that in commonly investigated model plants in two important aspects: (i) the perianth develops a photosynthetic system, after fertilization, and persists until seed ripening; and (ii) the ripe seed contains an immature embryo which continues to mature off the mother plant. The possible roles of cytokinins in these...
متن کاملPost-floral perianth functionality: contribution of persistent sepals to seed development in Helleborus foetidus (Ranunculaceae).
The perianth persists after flowering in many plants, yet its post-floral functionality has been little investigated, and the few studies available provide ambiguous evidence. This paper tests the hypothesis that the green persistent sepals of the perennial herb, Helleborus foetidus, contribute to the plant's fitness by enhancing seed number and/or size. Post-floral contribution of the calyx to...
