  • This experiment was conducted to determine the effect of chemicals and their concentrations, priming temperature and duration, and different germination temperature on germinability of salvia seeds. The highest percentage of germination was obtained with 50 or 100 mM $KH_2PO_4$, or with -0.50 or -0.75 MPa PEG 8000. When number of days to attain 50% of the final germination percentage (T50) and mean number of days to germination (MDG) were taken into account, 50 mM $KH_2PO_4$ or -0.50 MPa PEG was most effective for early germination. No seeds germinated when primed in $K_3PO_4$ or NaOH solution. Priming the seeds at $20^{\circ}C$ was better than priming at $15^{\circ}C$ or $25^{\circ}C$. Priming at $20^{\circ}C$ for 4 or 6 days reduced the MDG by 2.3 days compared with nonprimed seeds. Seeds primed with -0.50 MPa PEG at $20^{\circ}C$ showed a high germination percentage with reduced T50 and MDG. When seeds were primed in a mixture of -0.50 MPa PEG and 50 mM $KH_2PO_4$ solution and germinated at $30^{\circ}C$ or $35^{\circ}C$, percent germination was lower than nonprimed seeds. However, the combined treatment retained the priming effect for reducing T50 and MDG.

  • Effect of effective microorganisms on the growth of plant (salvia sp.) was investigated. Microorganisms used were photosynthetic bacteria, lactic acid bacteria and yeasts. When photosynthetic bacteria were inoculated to soil by 100 dilution, treated plants showed 160% growth by length compared to control. When photosynthetic bacteria, lactic acid bacteria and yeasts were mixed, diluted by 10 and inoculated to soil, the plants showed 212% growth compared to control. Microbial populations were increased in the treated soil.
