Plant Mating Systems Often Vary Widely Among Populations
Most flowering plants are hermaphroditic, yet the proportion of seeds fertilized by self and outcross pollen varies widely among species, ranging from predominant self-fertilization to exclusive outcrossing.

: Total fertilization failure (TFF) happens in 1–3% of total intracytoplasmic sperm injection (ICSI) cycles and may reoccur in sequent cycles. Regardless the high success rate with the applying of intracytoplasmic sperm injection (ICSI), there's still a ...

Connection of fertilization conditions of sour cherry and meteorological parameters
Our analyses showed that the degree of free fertilization is mostly influenced by maximum temperature and sunshine duration.We found that free fertilization ratio increases with higher daily maximum temperatures; similar results characterise sunshine ...

The Ability to Self-fertilization as a Factor of Eurybiontness in Freshwater Pulmonate Mollusks [PDF]
The reproduction parameters of eurybiontic (Lymnaea stagnalis) and stenobiontic (Stagnicola corvus) species originating from the reservoirs of Belarus and Russia with the different anthropogenic pollution are determined during experiment with cross ...

Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...

Mixed Mating System Are Regulated by Fecundity in Shorea curtisii (Dipterocarpaceae) as Revealed by Comparison under Different Pollen Limited Conditions. [PDF]
The maintenance of mixed mating was studied in Shorea curtisii, a dominant and widely distributed dipterocarp species in Southeast Asia. Paternity and hierarchical Bayesian analyses were used to estimate the parameters of pollen dispersal kernel, male ...

Cross- and self-fertilization of plants
This essay considers Charles Darwin's late work, Cross- and Self-Fertilization of Plants, locating it in the overall context of Darwin's thought and ideas. It is shown how it is part of a long-term interest in the purpose of sexuality, and how it complements Darwin's earlier book on the ...

Is self‐fertilization an evolutionary dead end? [PDF]
SummaryA compound hypothesis positing that self‐fertilization is an evolutionary dead end conflates two distinct claims: the transition from outcrossing to selfing is unidirectional; and the diversification rate, or the balance of the speciation and extinction rate, is negative for selfing species.
