| The effect of sodium hypochlorite treatment on the germination of cattail (Typha spp.) seeds was investigated in growth chambers maintained on a 14-h photoperiod with various temperatures and light intensities. Germination rates of seeds were, in general, enhanced by the increase of light intensity and temperature regardless of cattail species. Seeds of T. oreientalis had 4.3, 13.0 and $7.3%$ germination at temperatures of 20, 25 and $30^{circ}$C, respectively, under light intensity of 7.5${mu}mol{cdot}m^{-2}{cdot}s^{-1}$. T. angustata showed higher germination rate, thus, 10.7, 22.7 and $50.7%$ under same temperature and light environment. Under high light intensity of 79.5${mu}mol{cdot}m^{-2}{cdot}s^{-1}$, the germination rates of T. oreintalis and T angustata were $78.3%$ and $88.7%$ at $30^{circ}$C, respectively. Scarification of seeds with NaOC1 ($4%$, available chlorine) increased germination rate in both species, especially even at low temperature of $20^{circ}$C. Germination speed was also enhanced by NaOC1 treatment. High light intensity further increased the germination rate. When NaOC1 treated seeds were sowed on the soil surface in plastic house, the seedling emergence was nearly $100%$. Untreated seeds of T. oreintalis and T. angustara showed 40 and $50%$, respectively, in germination under same condition. However, when the depth of soil covering was over 1.0 cm, seedling emergence was retarded more than 1 month. On the process of seedling development, emergence of mesocoty1 occurred firstly and after than primary root and first leaf were developed on the end of elongated mesocotyl. These results suggest that the promotion of seed germination by NaOC1 pretreament may be induced from the increase of light absorptivity as well as water permeability through scarifying and bleaching the seed coat. |
