초록

This research was carried out to determinethe characteristics of germination in relation to temperature,and seedling emergence and growth affected by soilmoisture in forage millet. The seeds of forage millet couldgerminate at more than 15℃ at the rate of 0, 90.5, 97.3and 96.8% respectively 10 days after seeding at 10, 15, 20and 25 ℃. The result showed that the temperature needsto be 15 ℃ or more for the seeds to germinate. The effectsof seeding depth on the growth characteristics andemergence of millet seed were investigated in waters anddirect seeding methods by thoroughly mixing the seed andsoil. In water treatment, the emergence rates were 3.7% at15 ℃, 7.6% at 20 ℃, 6.3% at 25 ℃, while direct seedingtreatment showed the emergence rates of 65.6, 75 and 71%at 15, 20 and 25 ℃, respectively. At 15, 20, and 25 ℃,seeds in water seeding could germinate at 0.5, 1.8, 1.5 cmof soil depth, while in direct seeding, they could germinateat the depth of 9.5, 10.0, 9.9 cm. When the initial growthcharacteristics of the seeds were investigated, there waspositive correlation between seeding depth and mesocotyllength in both water and direct seed methods. Growth anddevelopment in terms of leaf age, root length, coleoptilesand mesocotyl length, and plant height were foundmaximum at 0.5 cm soil depth for water seeding, and 3-5 cmsoil depth for direct seeding. Results showed that therewere close relationship among temperature, soil depth andmoisture acquiring methods, and the combination of thesefactors greatly affected the initial growth characteristics anddevelopment of millet seeds. It can be concluded that, toget good seedling stand and germination of millet seed,millet should grown in field condition at the depth of 0.5 cmor less for water seeding, and 3-5 cm for direct seedingmethod.
