این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Effects of Various Cryoprotective Agents and Extender Osmolality on Post-thawed Ram Semen
The influence of different extender osmolality levels and the presence of different cryoprotectants on the postthawed semen’s characteristics and post-thawed plasma membrane integrity of ram spermatozoa were studied. Ram semen was frozen with TRIS-egg yolk based extender according to two-step dilution procedures. The final concentrations of the cryoprotectants: 6% glycerol, 6% 1,2propanediol, 6...
متن کاملCombined Effect of Trolox and EDTA on Frozen-Thawed Sperm Quality
The freezing and thawing process not only is associated with serious damage to sperm such as damage to the plasma membrane and the acrosomal membrane but also changes the membrane permeability to some ions including calcium. Also, the generation of oxygen free radicals is increased during the freezing-thawing process. The purpose of this study was to evaluate of the effects of Trolox as an anti...
متن کاملEffect of hydrogen peroxide on thawed ovine sperm motility
Oxidative stress, resulting from excessive levels of ROS in semen, has a negative impact on functional parameters and sperm fertility. In this study we examined the influence of the oxidative stress induced by hydrogen peroxide (H2O2) in ovine sperm motility after thawing and catalase (CAT) ability to preserve sperm motility. Semen was incubated at 37°C with 100 μM H2O2, 1 U catalase + 100 μM H...
متن کاملThe Cryoprotective Effect on Frozen-thawed Boar Semen of Egg Yolk Low Density Lipoproteins
In order to protect the spermatozoa against cold shock, hen egg yolk is widely used as a cryoprotective agent in semen freezing extenders for domestic animals. The protective action of yolk is largely presumed to be due to low density lipoproteins (LDL). The effects of LDL on sperm quality of bull and northern pike (Esox lucius) after freezing-thawing have been reported, but no study has been m...
