모과(Chaenomeles Sinensis Koehne) 種子 發芽特性에 關한 硏究 : Chaenomeles sinensis Koehne = A Study on the Seed Germination of Chinese Quince

국문 초록 (Abstract)

아세아가 原産이며 우리나라에도 自生하는 主要한 造景用 樹木으로 평가받고 있는 모과(木瓜 chaenomeles sinensis koehne)에 關하여 種子發芽 特性에 關하여 1978∼1979年에 걸쳐 硏究 調査하였던 바 그 主要 結果를 要約하면 다음과 같다.
1. 各 播種된 모과種子는 休眼中에 있으며 약 60日以上의 低溫處理는 休眼을 거의 完壁하게 打破하였다.
2. 播種된 種子를 水洗後 1年間 乾燥貯藏한 것은 完全히 發芽力을 喪失하였다.
3. 各 播種된 種子의 一部 또는 全部 外內皮를 除外하는 것은 發芽를 顯著히 促進하였다.
4. Aceton이나 Alcohol등에 種子를 沈漬하는 것은 外皮 및 內皮에 存在하는 發芽抑制와 關係되는 物質을 용출시켜 주므로서 發芽를 促進하는데 效果的이었다.

다국어 초록 (Multilingual Abstract)

A survey and investigations have been made on the seed germination of Chinese quince (Chaenomeles sinensis koehne) which is native to Asia including Korea and becoming popular as an important plant material for landscape.
The results are summarized as follows:
1. The seeds were in dormancy when harvested in the fall. But stratification of the seeds at 5℃ for more than 60 days completely released the dormancy.
2. The seeds, washed, dried, and stored at room temperature completely lost viability within a year.
3. Scarification, removal of seed coat and 1 or integuments significantly accelerated the seed germination of unchilled seeds.
4. Soaking seed in 5-10% aceton or methanol for 4 hours was effective in accelerating seed germination of unchilled seeds, possibly by removing inhibitor-like substances from the seed coat and/or integuments.
