다국어 초록 (Multilingual Abstract)

These studies were carried out to know the variation of seeds and top height growth of seedlings by locations along the southern sea coast in Korea. The results obtained were summarized as follows: 1. The number of seeds per cone was showed to be the highest in Chung-mu and the lowest in Wul-jin. 2. The variations of seed length and seed width were showed to be high in Wul-jin and Young-duck along the eastern sea and Bul-kyo, Mok-po along the southern sea. 3. The number of cotyledons was not correlations between seed length and seed width. And the number of cotyledon was showed to be 7 leaves ie. all locations. 4. The results of T-test were not significant by all locations. 5. By the locations, the results of analysis of variance were not significant in top height growth of seedlings by sowing of the present year, but high significant in July of the next year. In conclusion, the number of seeds per cone was showed to be high in the variation of seed characters and the top height growth of seedlings was showed to be significant in sowing of the next year.
