CARPEL DEVELOPMENT IN DRIMYS LANCEOLATA
American Journal of Botany, 1966The dissimilar carpels of representatives of the Tasmannia and Wintera sections of the genus Drimys have been investigated developmentally with particular attention to the presence of peltation. In Drimys winteri of the Wintera section peltation results

Genetic and Phenotypic Analyses of Carpel Development in Arabidopsis
2023Carpels are the female reproductive organs of the flower, organized in a gynoecium, which is likely the most complex organ of the plant. The gynoecium provides protection for the ovules, helps to discriminate between male gametophytes, and facilitates successful pollination.

Carpel Polymorphism in Citrus Fruit
Botanical Gazette, 1990Each citrus species and cultivar in the Aurantioideae exhibits a distinct range of carpel (segment) numbers within their fruits. The observed range of segments for fruit within any species or cultivar can be influenced by branch location on a tree. The carpel number for all fruits produced on a single tree may have a symmetrical, unimodal distribution,

Open Carpels with Ovules in Fabaceae
International Journal of Plant Sciences, 2001Young open carpels with developing ovules exposed to view are a regularly observed stage in development in 25 caesalpinioid species and one papilionoid legume studied. In all, the carpel margins later become appressed and sealed. A literature survey revealed examples of open, ovulate carpel primordia in 42 species in 19 additional angiosperm families ...

The Origin and Evolution of the Angiosperm Carpel
2007The angiosperm carpel is one of the defining characteristics of flowering plants. Carpels are unique to angiosperms and are found in all of its members. Yet, due to the distinctive structure and function of carpels, deducing homologies among carpels and other seed-plant organs has been difficult.

Fruit growth and development is the result of several processes acting in a coordinated manner. The problem of assigning a specific function to physiological and molecular factors contributing to fruit development is aggravated by the presence of tissues with different functions, dynamics of growth, and carbohydrate accumulation.

Vascularization of the Carpel of Myristica fragrans
Botanical Gazette, 19591. In the pistillate flower of Myristica fragrans Von Houtt. the stele of the pedicel, after giving rise to the vascular traces to the bracteoles and perianth, continues into the gynophore and then into the wall of the gynoecium, where it gives rise to branches both to the periphery and, at a higher level, to the center. 2.

CONDUPLICATE AND SPECIALIZED CARPELS IN THE ALISMATALES
American Journal of Botany, 1976Carpel closure and stigmatic localization in the Alismatales have accompanied decreases in carpel size and numbers of ovules per carpel and increases in carpel numbers per flower. The most specialized carpels are uniovulate and indehiscent and occur acyclically in great numbers in each flower, with strong trends toward monoecism and even dioecism.

Carpel Dehiscence in Firmiana Simplex
Botanical Gazette, 19321. The young carpel of Firmiana simplex is closed at first, then opens widely, later closes intimately, and again becomes widely opened. 2. Coalescence of the two rims of a single carpel is by means of close approximation, cell division, and cell enlargement. 3.
