Preventing self-fertilization: Insights from Ziziphus species [PDF]

open access: yesFrontiers in Plant Science, 2023
The fitness of self-progeny individuals is inferior to that of their outcrossed counterparts, resulting in a reduction in a plant population’s ability to survive and reproduce.

Male reproductive success is not strongly affected by phenological changes in mate availability in monoecious Sagittaria latifolia [PDF]

open access: yesRoyal Society Open Science, 2023
Many plants express their female and male sex roles at different times (dichogamy), with important consequences for mating. Dichogamy can yield mate limitation via biased floral sex ratios, particularly at the beginning and end of the flowering season ...

Mapping the Genetic Regions Responsible for Key Phenology-Related Traits in the European Hazelnut [PDF]

open access: yesFrontiers in Plant Science, 2021
An increasing interest in the cultivation of (European) hazelnut (Corylus avellana) is driving a demand to breed cultivars adapted to non-conventional environments, particularly in the context of incipient climate change. Given that plant phenology is so

Dichogamy in angiosperms [PDF]

open access: yesBotanical Review, The, 1993
We obtained information on dichogamy and other aspects of the biology of over 4200 species of angiosperms from several hundred published and unpublished sources. We used this information to describe patterns of occurrence of dichogamy and to test specific hypotheses relating dichogamy to other characteristics of plants or their environments.

Floral Biology, Breeding System and Conservation Implications for the Azorean Endemic Azorina vidalii (Campanulaceae) [PDF]

open access: yesPlants
This study investigates the seasonal and floral phenology, breeding strategies, and floral morphology of Azorina vidalii, an Azorean endemic Campanulaceae with hermaphroditic, protandrous flowers, dichogamy and secondary pollen presentation.

Investigating morphological and biological reproductive traits in self-fertile and -infertile macadamia cultivars [PDF]

open access: yesBMC Plant Biology
Self-fertility is a commercially valuable trait in crop species, enabling fruit set without reliance on pollinators or external pollinisers. In macadamia, most cultivars are self-infertile, though some can produce nuts with self-pollen.

Effects of floral sexual investment and dichogamy on floral longevity [PDF]

open access: yesJournal of Plant Ecology, 2015
Aims Floral longevity, the duration that a flower remains open and functional, varies greatly among species. Variation in floral longevity has been considered to be optimal strategy for resource allocation under different ecological conditions, mainly determined by the rates of pollination and cost of flower maintenance.

Genome-wide identification of a MADS-box transcription factor family and their expression during floral development in Coptis teeta wall [PDF]

open access: yesBMC Plant Biology
Background MADS-box transcription factors have been shown to be involved in multiple developmental processes, including the regulation of floral organ formation and pollen maturation. However, the role of the MADS-box gene family in floral development of

Movement-assisted dichogamy in Atamisquea emarginata (Capparaceae)

open access: yesPlant Systematics and Evolution, 2003
Various aspects of the reproductive biology of Atamisquea emarginata Miers ex Hook. et Arn. were studied in a population from Tucuman, northern Argentina. Flowering took place in late (austral) spring to early summer. The creamy white, entomophilous flowers were protandrous and lasted 3.5–4.5 days. A pleasant odor along with nectar and pollen attracted

Insect Pollination Enhances Yield and Physicochemical Quality Traits in Three Jujube Cultivars [PDF]

open access: yesInsects
Jujube (Ziziphus mauritiana Lam.) is a nutritionally rich tropical fruit which is native to South Asia. In Pakistan, there are 50 varieties of jujube, and approximately 24,000 tons of jujube is harvested annually from a growing area of nearly 5000 ...
