光波長, 照度, 光處理期間 및 GIBBERELLIN 處理가 Zoysia japonica 種子 發芽에 미치는 影響 = The effects of wave length of light intensity, duration of light treatment, and Gibberellin on germination of Zoysia japonica seeds

다국어 초록 (Multilingual Abstract)

A series of experiments was contucted in 1967 to investigate the effect of wave length of light, light intensity, duration of light treatment, and gibberellin on the germination of Zoysia japonica seeds. The wave length of light was controlled by using the color cellophane paper under the natural sun light condition. And under the fluorescent lamps the wave length fo light was combined with light intensities and durations of light treatment. To clearify the accurate effect of wave length, light intensity, duration of light treatment, and gibberellin, the light intensity which infiltrated through color cellophane paper was adjusted to 1,000 lux. The results are summarized as follows.
1) The gemination percentage was remarkably higher under the colorless and red cellophane paper than that of the blue or green cellophane paper.
2) The germination percentage was increased highly under the natural condition where the light intensity was more than 30,000 lux, but it was very low under 1,000 lux or 500 lux
3) Germination percentage was increased in prolonged light treatment and under the strong light intensity.
4) Gibberellin increased, more or less, the germination percentage, but it could not substitute the effect of light or stratification.
