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 ...

Effects of heat stress on development, quality and survival of Bos indicus and Bos taurus embryos produced in vitro
(2013-01-15)
Heat stress is an important cause of poor development and low survival rates in bovine embryos. Experiments were conducted to test the hypothesis that Bos indicus embryos are more resistant to heat stress than are Bos ...

Improving postcryopreservation survival capacity: an embryo-focused approach
(Brazilian Coll Animal Reproduction, 2013-07-01)
The major challenge for a greater dissemination of in vitro produced (IVP) bovine embryos is to improve embryonic survival after cryopreservation. The involvement of embryonic lipids on this issue is well documented. ...
Morphology, sex ratio and gene expression of Day 14 in vivo and in vitro bovine embryos
(2013-04-29)
The present study was designed to compare Day 14 bovine embryos that were produced entirely in vitro using the post-hatching development (PHD) system with in vivo-derived embryos without or with transient PHD culture from ...

Crucial surviving aspects for vitrified in vitro-produced bovine embryos
(Cambridge University Press, 2014-05-01)
The objective of the present study was to correlate some parameters (cleavage, blastocyst production, quality degree score, total cell number, fresh apoptosis and lipid content) with embryo survival after cryopreservation. ...
