during spring, summer and winter seasons, sistani donor cows, with normal reproductive status, were superovulated and embryos were recovered non-surgically on day 7. grade a blastocyst embryos were either transferred fresh (spring) or frozen (summer and winter). recovered embryos during summer and winter were exposed to glycerol and frozen using conventional method. during spring season, recipi...
Myrtle ) Myrtus communis L.) is a diploid plant belongs to the family of Myrtaceae and is considered as one of the important medicinal and ornamental plant. The present was performed to investigate the effect of salinity stress on morphological and physiological traits in myrtle. This study was conducted in an experiment of split plot in time according to a randomized complete block desig...
High ambient temperature is the major constraint on Buffalo productivity. The aim of this study was to evaluate the reproductive performance and thyroid gland function in winter and summer seasons in Khuzestan buffalo bulls. Six male indigenous buffaloes of Khuzestan with nearly the same age (2-3 years old) and weight were used. Semen and blood samples through jugular vein were collected, every...
in order to compare planting season effect on agronomic of characters and yield of dill (anethum graveolens l.) an experiment based on completely randomized design with three replications was conducted in 2006-07 in esfahan province and three planting seasons (spring, summer and autumn) were evaluated. essential oil compositions were obtained by clevenger and recognized by gc-mass and gc. accor...
