In Vitro Development of Ovine Embryos Following Maturation Under Limited CO2
(2005)An experiment was conducted to examine the influence of CO2 during in vitro oocyte maturation on the in vitro ovine embryo development. Three treatments of CO2 were subjected to the oocyte development. Those were 2h gasses ... -
Yield potential of ten peanut introgression lines derived from crosses between Arachis cardenassii and A. hypogaea
(2005)Diploid species of peanut (Arachis cardenasii) showed no symptoms of PStV infection when mechanically inoculated with PStV. Some introgression lines derived from A. cardenasii and A. hypogaea hybridization have been ... -
Heavy metals bioaccumulation of several Bradyrhizobium japonicum strains
(2005)Heavy metal utilization in industry and agriculture have caused an environmental problem to existing life. Bioaccumulation is made up by a concentration of certain chemical compounds in living tissues. The objective of ... -

(2005)Sperm collected from cauda epididymis is a source of male gametes. The purposes of this study was to evaluate an quality of frozen-thawed sperm of garut ram which was collected from cauda epididymis and cryopreserved with ... -
Detection of Antimicrobial Compounds Isolated from Several Tropical Lentinus by Bioautographic Method
(2005)The antimicrobial compounds extracted either from culture filtrates or mycelia of several tropical Lentinus species could be detected their existences and locations by bioautographic method. For this purpose, the crude ... -
In Vitro Fertilization and Embryo Development of Vitrified Ovine Oocytes Stressed in Sucrose
(2005)Experiments were conducted on the morphology, fertilization and embryo development rate of vitrified ovine oocytes matured in vitro. Three vitrification solutions were used for vitrification. PBS supplemented with 1% BSA, ... -
Effect of Zn Supplemented to Immune Status Premenopausal Women Intervented with Isoflavoned Drinking
(2005)The research was conducted to find out the effect of Zn supplement to immune status of premenopausal women intervented with isoflavoned drinking. Respondents were 22 women, more than 40 year of age. They were divided into ... -
Molecular Phylogeny of Agrioglypta Meyrick and Talanga Moore (Lepidoptera: Crambidae; Spilomelinae) Inferred from Nuclear EF-1
(2005)The phylogeny of the two closely- related genera, Agrioglypta Meyrick and Talanga Moore, was inferred from nucleotide sequence variation across a 973-bp region in the nuclear elongation factor-1α (EF-1α) gene. Seven species ... -
Cloning of Genomic DNA Flanking Transposon in the Nonpathogenic Mutant of Xanthomonas axonopodis pv. glycines M715
(2005)The objective of this work is to clone flanking DNA derived from Tn-5 mutagenesis of wild type strain Xanthomonas axonopodis pv. glycines as first step to clone and to identify the gene involved in pathogenicity mechanism. ... -
Embryology of Swainsona formosa (Fabaceae): Anther and Ovule Development
(2005)Our study showed that floral morphology and anatomy in Swainsona formosa were typical of leguminous flower. The anthers were found to be tetrasporangiate, with a 3-layered wall below the epidermis. The wall was comprised ... -
