Corn production and plant characteristics response to N fertilization management in dry-land conventional tillage system
Nitrogen (N) application management needs to be refined for low yielding environments under dryland conditions. This 3-yr study examined nitrogen fertilization management effects on corn (Zea mays L.) plant characteristics and grain yield in rain fed environment under conventional tillage system. Nitrogen fertilization management consisted of two timing methods of N application [all N at planti...

P-23: Effect of Melatonin on In vitro Maturation, Fertilization and Resulted Embryo Development in Mouse
Background: Melatonin has been recognised as effective reactive oxygen species (ROS) scavenger. antioxident melatonin effects has been expressed in management of cancer, alzheimer, diabet diseases. This study designed to determine the effect of melatonin on in vitro oocytes maturation and fertilization and cleavage and blastocyst development rate of mouse. Materials and Methods: Cumulus - oocyt...
متن کاملP-102: Recurrent In Vitro Fertilization Failure and Hereditary Thrombophilia
a:4:{s:10:"Background";s:363:"The largest percentage of failed in vitro fertilization (IVF) cycles are due to lack of implantation. As hereditary thrombophilia can cause in placentation failure, it may have a role in recurrent IVF failure. The aim of this case-control study was to determine whether or not hereditary thrombophilia is more prevalent in women with recurrent IVF failures.";s:19:"Ma...
متن کاملP-103: Connection of The G6PDH Activity on Fertilization and Developmental Competency in The Bovine
Background: This study was conducted in order to determine whether BCB staining performed on immature bovine oocytes to assess G6pdhlevel has an impact on ivf/ivp technology in bovine embryos. Both spermatozoa and oocytes metabolize glucose through the pentose phosphate pathway (PPP), and NADPH appears necessary for gamete fusion. Activity of glucose 6-phosphate dehydrogenase (G6PDH), the key e...
