Effects of Temperature, pH, Light and Degree of Oxygen Supply on the Germination of Papaver somniferum L. Seeds

온도, pH, 광 및 수침이 양귀비 ( Papaver somniferum L. ) 종자발아에 미치는 영향

Effects of temperature, pH, light-and-dark and degree of oxygen supply on germination of Papaver somniferum L. seeds were investigated. The optimum temperature of the germination was 2$0^{\circ}C$, but the germination was decreased as temperatures changed to the upper and lower. The largest elongation of both radicle and hypocotyl also occurred at 2$0^{\circ}C$. The best germination occurred at pH 7 but this decreased suddenly the above and below of that pH value. Although no effect of light-and-dark on the germination was, this was restricted under limited. oxyten supply in terms of underwater germination as compared with abovewater one.
