There is currently much interest in assisted reproduction techniques in the horse, however, many aspects of oocyte maturation, fertilization, and embryo development in the horse differ from those in other species. Because of the close attachment of the equine oocyte to the follicle wall, scraping of the follicle is the most effective method for oocyte recovery. A notable feature of equine oocyt...

After natural or artificial insemination, the spermatozoon starts a journey from the site of deposition to the place of fertilization. However, only a small subset of the spermatozoa deposited achieves their goal: to reach and fertilize the egg. Factors involved in controlling sperm transport and fertilization include the female reproductive tract environment, cell-cell interactions, gene expre...

The fitness of self-progeny individuals is inferior to that their outcrossed counterparts, resulting in a reduction plant population’s ability survive and reproduce. To prevent self‐fertilization, angiosperms with hermaphrodite flowers may exploit variety mechanisms, including synchronous dichogamy self-incompatibility. Synchronous involves two flowering morphs, strict within-morph synchronizat...

Competitive exclusion is to be expected between phylogenetically similar species that share traits and resources. However, may overcome this, either through differentiation of their responses biotic abiotic conditions, or by trait differentiation, thus enabling coexistence. We identified differences in phenotypic seven coexisting Carex competition fertilization pot experiments, before using lon...

Abstract Fertilization was doing to measure the success of sperm cryopreservation because it more informative. Sperm expected get that successfully fertilize egg well. The aim this study determine fertilization ability giant grouper (Epinephelus lanceolatus, Bloch 1790) 48 hours post-cryopreservation in fertilizing tiger eggs fuscoguttatus, Forskal 1775). carried out artificially using with 6% ...

Land devoted to plantation forestry (50millionha) has been increasing worldwide and the genus Eucalyptus is a popular plantation species (14millionha) for its rapid growth and ability to grow well on a wide range of sites. Fertilization is a common silvicultural tool to improve tree growth with potential effects on stand water use, but the relationship between wood growth and water use in respo...
