돼지감자에 있어서 播種期에 따른 二品種의 實用形疾의 變化 = Changes in Agronomic Characters of Two Jerusalem Artichoke Cultivars on Different Seeding Date

국문 초록 (Abstract)

本 硏究는 3月 29日부터 4月 26日까지 7日 간격으로 돼지감자의 白色種과 赤色種을 播種하여 實用形質의 變化를 究明하기 위하여 遂行되었는데, 其 結果는 다음과 같다.
塊莖收量과 一塊莖重 및 地上部의 乾物重은 白色種이 赤色種보다 더 무거웠으나 塊莖數는 赤色種이 더 많았다.
파종기가 늦을수록 두 品種 모두 塊莖收量, 一塊莖量, 地上部乾物重 및 草長이 감소되었고, 파종기의 遲延에 따르는 塊莖收量과 一塊莖重의 減少程度는 白色種에서보다 晩生種인 赤色種에서 더욱 뚜렷하였다.
塊莖收量은 白色種에서는 一塊莖重 및 地上部乾物重과 正의 相關關係가 있고, 赤色種에서는 塊莖數, 一塊莖重, 乾物重 및 草長과 有意的인 相關關係가 있었다.
一塊莖重은 地上部乾物重 및 草長과도 두 品種 共히 相關關係가 있었으나, 白色種에서의 塊莖數는 다른 形質과 相關이 없었다.

다국어 초록 (Multilingual Abstract)

This study was conducted to clarify the changes in the characters of Jerusalem artichoke cultivars, the white and the red, which were planted with seven day intervals from March 29 to April 26 on Cheju island.
The results obtained are summarized as follows;
The white cultivar was higher in the tuber yield, and heavier in the weight of a tuber and the dry top weight than the red, but the number of tubers was larger in the red than in the white.
As the seeding date was late, the tuber yield, the weight of a tuber, the dry top weight and the plant length decreased in the both cultivars. The decrease of the tuber yield and the weight of a tuber was more remarkable in the red than in the white with delaying seeding date.
The tuber yield was positively correlated with the weight of a tuber and the dry top weight in the white, and with the number of tubers, the weight of a tuber, the dry top weight and the plant length in the red.
The weight of a tuber had correlation with the dry top weight and the plant length in the both cultivars.
There was no relation between the number of tubers and the other characters of the white.
