Study was conducted to determine the effect of temperature, scarification, the pH, light duration and salt concentration on Senecio vulgaris L., Taraxacum officinale L. and Tragopogo pratensis L. seeds. In the study results were determined the highest germination rate in 15 degrees C for S. vulgaris, 20 degrees C for T. officinale and 10 degrees C for T. pratensis, at each of the three seeds in 6 months in waiting period, 7 for pH, 16 hours light / 8 hours dark for S. vulgaris and T. officinale, 24 hours darkness for T. pratensis and in control for salt concentration in each of the three seeds. In case of the culture of these three weeds which used medical should be taken into the consideration to these conditions.
