The objective of this research isto study the in vitro effect of some plant hormones (growth regulators) BAP,NAA, 2,4-D, and genotype on callus and bud formation from embryonic axes of two Soybean cultivar seeds (sb-44, sb-172). The embryonic axes were cultured on MS basal medium and MS supplemented with 1, 2, 3 mg/l BAP alone and in combination with 0.5 mg/l NAA.The cultures were maintained at 25 C°±1 with photoperiod of 16 hours light (2000-2500 lux) and 8 hours dark.The highest percentage92.5% and mean average 4.63 of callus formation were recorded on MS medium containing BAP (3 mg/l) and NAA (0.5 mg/l). The highest percentage 67.5% and average 3.38 of buds formation were obtained on MS medium supplemented 1 mg/l BAP and 0.5 mg/l NAA in cultivar sb-44. The percentage of callus formation increased, while the percentage of bud formation decreased with each increase in BAP concentration when used alone. A positive increase was observed in all mediums in the combination of 0.5 mg/l NAA or 0.5 mg/l 2. 4-D in the two cultivars used in this study. This study showed the genotypic difference effect on callus and bud formation.Roots were formed from allplantlets cultured on MS medium without plant hormones.Rooted plantlets were transferred into pots with nutrient soil, irrigated with water, and adapted tolaboratory conditions. Good plants grown to maturity were obtained in 12-13 weeks.

The objective of this research is to propagate Mentha puligium in vitro, shoot tips and nodal explant were planted with 0.5-1 cm length on MS (Murashige's and Skoog) medium with various concentrations (0.5-1-2-3-4) mg/L of cytokinin BAP.
The objective of this study is to compare the effect of five different Nacl concentration (0,50,100,150,200 mM) on seeds germination and seedling growth of two cultivars of soybean (sb-44,sb-172). Seeds were germinated in petri dishes with sterile filter paper moistened with 10 ml of test solution at 25 c˚ in dark . The obtained results showed that germination percentage , length of root and hypocotyl were decreased with the increase of the Nacl concentration in the medium. The best values was from cultivar sb-44 . After seven days of incubation , significant differences were observed between control and treated seeds . Germinated seeds were subcultured on basal Murashige and Skoog medium solid at the same Nacl concentration . The roots growth was mor affected by 200 mM Nacl compared to seedling growth . Plantlets were transfered into pots with nutrient soil , irrigated with saline water and were adapted at laboratory . we obtained good plants grew to maturity in 10- 12 weeks .

Tissue culture process of date palm propagation via bud proliferation is fully described. Adventitious plantlets were obtained from shoot tips. axillary buds and the bottom of young leaves of five date palm cultivars (Sefri, Zahdi, Rizzez, Khalas and Hillaly).
Isoflavones occurring in soybean seed have a positive effect on the health of humans, especially in cancer prevention. This positive impact may be a result of their antioxidant properties, estrogenic activity, or a combination of both mechanisms. The purpose of this study was to quantify and compare levels of three major isoflavones in soybean seeds from three sources (Alghab area, Faculty of Agriculture, imported from China).
