Polyembryony increases embryo and seedling mortality but also enhances seed individual survival in Handroanthus species (Bignoniaceae)
(Elsevier Gmbh, Urban & Fischer Verlag, 2012-01-01)
Polyembryony seems to be advantageous to mother plants in detriment of their siblings which face competition since the beginning of seed development. This competition may limit the turnover of embryos into seedlings and ...
Influence of egg pre-storage heating period and storage length on incubation results
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2008-03-01)
This experiment aimed at evaluating the influence of different heating times of settable eggs of Cobb 500® broiler breeders before submitting them to different storage periods on egg weight loss, embryo mortality, and ...
Cryogenic preservation of embryos of Prochilodus lineatus (Valenciennes, 1836) (Characiforme; Prochilodontidae)
(Cambridge University Press, 2009-02-01)
While the freezing techniques of mammal embryos have been providing promising results, the cryopreservation of teleostean eggs and embryos have remained unsuccessful up to now. Therefore, this work aimed to develop a ...
