Comparative Efficacy of Histrelin Acetate and hCG for Inducing Ovulation in Brazilian Northeastern Jennies (Equus africanus asinus)
(2020-09-01)
The goal of this study was to compare the efficiency of histrelin acetate (GnRH analog) and human chorionic gonadotropin (hCG) to hasten ovulation in Brazilian Northeastern jennies (Equus africanus asinus). Thirty cycles ...
Ovule and female gametophyte in representatives of Nymphaeasubgenus Hydrocallis and Victoria (Nymphaeaceae; Nymphaeoideae)
(Elsevier, 2014)
Nymphaeaceae occupies an important phylogenetic position because of their placement as one of the basal angiosperms. From this perspective, morphological studies in the family are of great value to under- standing plant ...
Gibberellins negatively modulate ovule number in plants
(Company of Biologists, 2018-07)
Ovule formation is a complex developmental process in plants, with a strong impact on the production of seeds. Ovule primordia initiation is controlled by a gene network, including components of the signaling pathways of ...
Ovulation and ovulation rate in ewes under grazing conditions: factors affecting the response to short-term supplementation
(2021-02-01)
The relationships between ovulation rate and nutrition remain confused, probably because of uncontrolled variation in experimental conditions. To help resolve the problem, we analyzed data from 20 experiments conducted ...
Ovule, fruit and seed development in Abolboda (Xyridaceae, Poales): implications for taxonomy and phylogeny
(Wiley-Blackwell, 2014-05-01)
Xyridaceae belongs to the xyrid clade of Poales, but the phylogenetic position of the xyrid families is only weakly supported. Xyridaceae is divided into two subfamilies and five genera, the relationships of which remain ...
Development and fate of the postovulatory follicle complex, postovulatory follicle, and observations on folliculogenesis and oocyte atresia in ovulated common snook, Centropomus undecimalis (Bloch, 1792)
(2017-04-01)
The common snook, Centropomus undecimalis, was induced to ovulate using a time-release, GnRH analogue. Ovulation occurred the afternoon or evening the day after hormone administration. The time of ovulation was established ...
Pollination unpredictability and ovule number in a South-Andean Proteaceae along a rainfall gradient
(Csiro Publishing, 2016-02)
Pollen limitation occurs frequently in plant populations and, as result, many ovules are wasted. One possible adaptive explanation posits that ovule overproduction represents a 'bet-hedging' strategy against pollination ...
Is an ovulation-inducing factor (OIF) present in the seminal plasma of rabbits?
(ELSEVIER SCIENCE BV, 2011)
Inducing ovulation with oestradiol cypionate allows flexibility in the timing of insemination and removes the need for gonadotrophin-releasing hormone in timed AI protocols for dairy cows
(Csiro Publishing, 2017-01-01)
The effects of addition of gonadotrophin-releasing hormone (GnRH) to a progesterone plus oestradiol-based protocol and timing of insemination in Holstein cows treated for timed AI (TAI) were evaluated. Cows (n=481) received ...
Patrones distintivos de deposición de calosa proveen evidencia temprana de aborto de óvulos en el arbusto andromonoico Caesalpinia gilliesiiDistinctive patterns of callose deposition provide an early sign of ovule abortion in the andromonoecious shrub Caesalpinia gilliesii
(Sociedad Argentina de Botánica, 2009-07)
Ovule abortion may lead to the partial or complete reduction of the number of functional ovules in the ovary and then is the primary factor that determines the sexual expression of the plant. In different species, ovule ...
