Photosynthetic irradiance response of vegetative and reproductive structures of the green-flowered deciduous perennial green hellebore was studied by the comparative use of chlorophyll (Chl) fluorescence techniques and gas exchange measurements. All the Chl-containing organs (leaves, sepals, stalks, and fruits) examined were photosynthetically active showing high intrinsic efficiencies of photosystem 2 (Fv/Fm: 0.75–0.79) after dark adaptation. Even in the smaller fertile and sterile parts of… Expand

Figures and Tables from this paper

Why Snowdrop (Galanthus nivalis L.) tepals have green marks
TLDR
A second relevant function is proposed for the green patterned inner tepals in performing an efficient photosynthesis and providing the flower and the developing seeds with photo-assimilates. Expand
Photosynthetic capacity of the capsule wall and its contribution to carbon fixation and seed yield in castor (Ricinus communis L.)
TLDR
The results indicate that castor capsule walls are photosynthetically active and contribute significantly to carbon fixation and seed yield accounting for 10 % photoassimilates towards seed weight. Expand
Characteristics of Photosystem II Behavior in Cotton (Gossypium hirsutum L.) Bract and Capsule Wall
TLDR
Results suggested that lower PS II photochemical activity in non-foliar organs may be result from limitations at the donor side of PS II and the acceptor sides of both photosystems. Expand
Functional transition in the floral receptacle of the sacred lotus (Nelumbo nucifera): from thermogenesis to photosynthesis.
TLDR
Receptacle δ13C before anthesis was similar to that of leaves; consistent with leaf photosynthesis being the source of C for these tissues, suggesting that 14-24% of C in mature receptacles is the result of refixation of respired CO2. Expand
Green plastids, maximal PSII photochemical efficiency and starch content of inner stem tissues of three Mediterranean woody species during the year
TLDR
It is supported that green plastids of wood ray and pith cells of three woody species with different life strategies common in the Mediterranean basin may help toward the re-fixation of the internally respired CO 2. Expand
The photosynthetic and structural differences between leaves and siliques of Brassica napus exposed to potassium deficiency
TLDR
Siliques had substantially smaller A than leaves, which was attributed to less efficient functioning of the photosynthetic apparatus, especially the integrated limitations of biochemical processes (Jmax and Vcmax) and α; however, siliques were slightly less sensitive to K deficiency. Expand
Anatomy and photosynthetic parameters of roots and leaves of two shade-adapted orchids, Dichaea cogniauxiana Shltr. and Epidendrum secundum Jacq.
TLDR
The diurnal titratable acidity fluctuations indicated crassulacean acid metabolism (CAM) in E. secundum leaves, associated with anatomical features like thick cuticle, large and vacuolated cells, and reduced stomata size and frequency, suggesting that in spite of active CO 2 fixation in roots during the day, the bulk of carbon is imported from the leaves. Expand
Photosynthetic activity of reproductive organs.
TLDR
The topic of ROP presents the community with a challenge to integrate the fields of photosynthesis, development, and stress responses. Expand
Photosynthetic properties of spring geophytes assessed by chlorophyll fluorescence analysis.
TLDR
Results confirm the ecological consistency of the three plant groups, with internal differences, and according to a new, fluorescence based heliophily index, all trees and five long-cycle herbs were definitely "shade" species, while four long- cycle herbs and three ephemerals were intermediate shade-tolerant. Expand
Effect of Glomus mosseae on chlorophyll content, chlorophyll fluorescence parameters, and chloroplast ultrastructure of beach plum (Prunus maritima) under NaCl stress
TLDR
It could be concluded that G. mosseae inoculation could protect the photosystem II (PSII) of beach plum, enhance the efficiency of primary light energy conversion and improve the primitive response of photosynthesis under salinity stress. Expand

Photosynthetic utilization of radiant energy by CAM Dendrobium flowers
TLDR
A low Chl/carotenoid ratio in mature flower perianth as a consequence of Chl content reduction in the course of flower development suggests a relief of irradiation stress via this mean. Expand
Photosynthetic activities of vegetative and fruiting tissues of tomato
TLDR
The onset of F(o) quenching at high photon flux densities suggested that all tissues contained a regulated mechanism for dissipating excess energy as heat. Expand
Photosynthetic activities in the petunia corolla.
TLDR
Corolla chloroplasts of Petunia might have a role in flower developmental processes and reduced efficiency of photosystem II photoreactions in the corolla was indicated by the ratio between variable and constant components of Chl fluorescence, which was lower in corollas compared to green leaves. Expand
Fruit initiation in Helleborus niger L. triggers chloroplast formation and photosynthesis in the perianth
TLDR
The metamorphosis of the sepals into photosynthetically active organs only occurs in fruit-bearing flowers and is arrested at a very early stage in controls in which the pistils are removed before pollination. Expand
Reproductive effort and floral photosynthesis in Spiranthes cernua (Orchidaceae).
TLDR
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. Expand
Characteristics of the Photosynthetic Apparatus and CO2-Fixation in the Flower Bud of Lilium. I. Corolla
TLDR
Although tepals performed positive net CO2-fixation from the microspore mother cell stage up to pollen mitosis but not during pollen maturation, the flower bud of Lilium may be considered not solely as a sink structure for the whole plant but also as a partly autonomous organ in terms of photosynthates.
