Gender variation of Dryas octopetala along snowmelt and latitudinal gradients in the Subarctic and the High Arctic [PDF]

open access: yes, 1999
We describe variations of floral traits of Dryas octopetala L. along a snowmelt gradient within and among three sites : 1) the Subarctic Latnjajaure in northernmost Sweden, 2) the High Arctic Longyearbyen and 3) Ny-Alesund, Svalbard in Norway, also High ...

Heading for a Breakdown: Assessing Evolution Through the Hybridization of Two Sexual Systems [PDF]

open access: yes, 2023
Hybridization is an important evolutionary pathway that has contributed to the world’s vast biodiversity. In plants, especially angiosperms, hybridization is known to be an important mechanism for speciation, phenotypic divergence, and changes in ...

Alocação de sexo dependente de tamanho em Solanum lycocarpum St. Hil. (Solanaceae) [PDF]

open access: yes, 2021
Resource allocation to reproduction can change depending on size, as predicted by the size-dependent sex allocation. This theory is based on the fact that small individuals will invest in the allocation of sex with lower cost of production, usually male ...

Involvement of ethylene biosynthesis and signalling in fruit set and early fruit development in zucchini squash (Cucurbita pepo L.) [PDF]

open access: yes, 2013
Background We have identified a kind of parthenocarpy in zucchini squash which is associated with an incomplete andromonoecy, i.e. a partial conversion of female into bisexual flowers.

Increasing Hermaphrodite Flowers using Plant Growth Regulators in Andromonoecious Jatropha curcas

open access: yesHAYATI Journal of Biosciences, 2014
Jatropha curcas (JC) is a crop with potential for use in biodiesel. Production of biodiesel requires plant seed as raw material, so the viability of JC for use in biodiesel will dependent greatly on the plant's production of flowers. Generally, this plant is monoecious, meaning it has both male and female flowers.

Floral sexuality and breeding system in gum karaya tree, Sterculia urens [PDF]

open access: yes, 2004
Comprehensive studies were carried out on phenology, floral sexuality, pollination biology, pollen-pistil interaction, breeding system and fruit and seed set on three populations of gum karaya tree (Sterculia urens).

Il fiore e la biologia fiorale [PDF]

open access: yes, 2011
Floral biology includes the series of processes which leads buds to evolve into flowers and fruits. Improving the knowledge on floral biology in olive is important both for scientific understanding and for practical reasons, since optimizing these ...

Flower morphology, gender functionality, and pollinator dynamics in Solanum carolinense: implications for the evolution of andromonoecy [PDF]

open access: yes, 2007
Morphological differences in flowers have important evolutionary consequences; they influence the plant's relationship with pollinators and are strongly correlated with sexual function in some breeding systems. Here, I explore the functional relationship

Expression and functional significance of andromonoecy in Solanum houstonii Martyn [PDF]

open access: yes, 2019
Andromonoecy, the production of both hermaphrodite and female-sterile (staminate) flowers in the same plant, is a sexual system that has evolved independently numerous times and is found in 33 families and ~4000 species of flowering plants. Over the last
