Abstract

To establish the mass propagation method of Typha orientatis Presl, several factors influencing seed germination were investigated. The best seed germination of T. orientalis was achieved under the light and 25~3$0^{\circ}C$ temperature. GA$_3$ tended to enhance seed germination, and 500 mg.L$^{-1}$ GA$_3$ showed 90.7% germination, which was 1.2 times of control. Compared to control, BA treatment prohibit seed germination. Especially, seeds were not germinated under 500 mg.L$^{-1}$ BA treatment. In case of KNO$_3$ and Ca(NO$_3$)$_2$ treatment, the germination rate was decreased by all concentrations, except 100 mM Ca(NO$_3$)$_2$.

본 연구는 부들의 대량번식법 개발을 목적으로 종자번식에 미치는 몇 가지 요인을 구명하기 위하여 실시하였다. 부들은 종자 발아적온은 25~3$0^{\circ}C$이며, 명발아성이었다. 종자에 GA$_3$,침지처리는 모든 농도 처리구 에서 발아율이 향상되는 경향을 보였다. 특히 500mg.L$^{-1}$ 처리구에서 90.7%의 발아율을 보여 대조구에 비해 약 1.2배정도 발아가 촉진되었다. BA 침지처리에 의해서는 대조구에 비하여 발아율이 현저히 낮아졌으며,500mg.L$^{-1}$ 처리구에서는 발아가 전혀 관찰되지 않았다. KNO$_3$및 Ca(NO$_3$)$_2$처리의 경우에는 Ca(NO$_3$)$_2$ 100mM 처리구를 제외한 모든 처리구에서 대조구에 비하여 발아율이 감소하였다.
