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 fruit and seed development was evaluated by manipulating sepal number and measuring the effect on… 

Figures and Tables from this paper

Function of leafy sepals in Paris polyphylla: photosynthate allocation and partitioning to the fruit and rhizome.

It is proposed that the sepals of P. polyphylla function partly as leaves to compensate for reproductive costs and that developing fruit and rhizomes compete for the photosynthates exported by leaves.

Change in floral orientation in Anisodus luridus (Solanaceae) protects pollen grains and facilitates development of fertilized ovules.

It is concluded that the change in floral orientation could enhance male and female fitness of A. luridus and is effectively adaptive to the alpine environments, indicating a strong selection by the combined pressure from various abiotic nonpollinator agents in shaping the floral traits of this alpine plant.

The role of post-floral persistent perianth in Helleborus viridis subsp. occidentalis (Ranunculaceae)

It is proposed that differences in the timing of leaf development and changes in the position of floral organs among the different Helleborus species, underlie a distinctive response to the ever-changing weather conditions of the European winters and springs.

Marcescent corollas as functional structures: effects on the fecundity of two insect-pollinated plants.

The simplicity of the experimental layout required to test for short-term fecundity effects of corolla marcescence should help to achieve a better understanding of the ecological and evolutionary correlates of this widespread but poorly understood trait.

Reversible colour change in leaves enhances pollinator attraction and reproductive success in Saururus chinensis (Saururaceae)

The reversible leaf colour change in S. chinensis appears to be adaptive because it enhances pollination success during flowering, with a small photosynthetic cost, while re-greening of these leaves after flowering helps to meet the carbon requirements for seed development.

Within-carpel and among-carpel competition during seed development, and selection on carpel number, in the apocarpous perennial herb Helleborus foetidus L. (Ranunculaceae)

It is concluded that selection on an optimum carpel number may be very variable across the species range, as the discussed reasons may impose constraints on eventual evolutionary response, thus contributing to the maintenance of the intra-individual variability inCarpel number.

Florivory affects pollinator visitation and female fitness in Nemophila menziesii

It is shown that natural and artificial petal damage decreased radial symmetry relative to controls and that both types of damage deterred pollinator activity, suggesting that Florivores may be an under-appreciated agent of selection in certain plants, although more experimental manipulation of florivory is needed to determine if it is important over a range of taxa.

Corolla herbivory, pollination success and fruit predation in complex flowers: an experimental study with Linaria lilacina (Scrophulariaceae).

Differences among plants in the proportion of flowers affected by herbivory and in the intensity of the damage inflicted on affected flowers may result in different opportunities for reproduction for plants in different seasons.

Within-plant heterogeneity in fecundity and herbivory induced by localized DNA hypomethylation in the perennial herb Helleborus foetidus.

Experimental manipulation of genomic DNA methylation level in leaves of wild-growing H. foetidus plants induced considerable within- plant heterogeneity in phenotypic and ecologically relevant traits (herbivore distribution), which supports the hypothesis that epigenetic mosaicism may partly account for within-plant variation.

Reproductive biology and nectar robbing in Salvia gesneriflora (Lamiaceae) and their consequences on plant reproductive success.

It is found that S. gesnerifl ora is a self-compatible species, although autonomous self-pollination did not occur, probably because their fl owers showed herkogamy and dichogamy.

Patterns of seed mass variation and their effects on seedling traits inAlliaria petiolata (Brassicaceae).

Differences in seed mass may affect seedling recruitment via effects on early seedling growth in this weedy species through changes in access to parental resources.

Developing fruit direct post-floral morphogenesis in Helleborus niger L.

In fertilized flowers of Helleborus niger L., the sepals grow, spread, and turn green, and the peduncles elongate, but these processes did not proceed to completion when the pistils were removed at the bud stage, but could be restored by the application of plant growth regulators.

Reproductive effort and floral photosynthesis in Spiranthes cernua (Orchidaceae).

The role of the inflorescence as a source and sink for carbon assimilation may lower the cost of reproduction and support frequent inflorescence production in Spiranthes cernua.

Carpels as leaves: meeting the carbon cost of reproduction in an alpine buttercup

It is plausible that the energy cost of male function equals or exceeds that of female function in this hermaphroditic species.

Geographical variation in autonomous self-pollination levels unrelated to pollinator service in Helleborus foetidus (Ranunculaceae).

Autonomous self-pollination may be considered as a mechanism enhancing plant reproductive success when plant access to pollen sources may limit seed production. We have studied the relationship

Developmental Changes in Gas Exchange Activity in Flowers, Berries, and Tendrils of Field-Grown Cabernet Sauvignon

Gas-exchange activity and seasonal evolution of some anatomical and biological characteristics linked to CO 2 assimilation processes were analyzed in different green structures on field-grown Cabernet Sauvignon grapevine to indicate features that could have important physiological implications when modeling canopy carbon gain of grapevines.

Inter- and intra-floral heterogeneity of nectar production in Helleborus foetidus L. (Ranunculaceae)

Three southern Spanish populations of Helleborusfoetidus L. (Ranunculaceae) were sampled for nectar content in the absence of nectarivorous flower visitors, finding high variances in nectar abundance occurred also among nectaries within the same flower.

The results show that seedlings originating from large seeds can better endure loss of cotyledons and aerial biomass and thus are better equipped to confront stress early in their lives.

Variation in structural gender in the hermaphrodite Helleborus foetidus (Ranunculaceae): within- and among-population patterns

The observed between-population variation in structural gender of Helleborus foetidus can be explained as a consequence of differences in self-pollination levels related to a flower’s “mating environment”.

Seedling establishment in Olea europaea: Seed size and microhabitat affect growth and survival1

It is concluded that establishment depended on microhabitats through facilitation and inhibition processes, and that seed size-related growth rate strongly affected seedling fate, it is noteworthy that the effectiveness of the size-correlated growth depended onmicrohabitat.
