목화 品種間 生育 및 收量 形質에 關한 硏究 = A Study on the Character Varietal on Growth and Yield of Cotton

국문 초록 (Abstract)

1995年 5月부터 12月까지 晋州産業大學校 特用作物實習圃場에서 木化 品種別 生育 및 收量을 調査 分析한 結果를 要約하면 다음과 같다.
1. 草長 및 節稈長은 品種間에 비슷하였으나 結果指數는 2∼9개 程度의 差異를 보였다.
2. 開花所要日數가 긴 品種이 開棉日數가 短縮되는 傾向이며, 株當開花數는 Tomcot SP 22가 46개로 가장 적었고, 株當 朔數는 Jackson Strain Cottomol 47개로 가장 많았다.
3. 莖直徑은 品種間에 비슷하였고 株當 全莖重은 서산읍 봉남동이 510g으로 가장 무거웠고, 株當根重은 임성현산이 48g으로 가장 무거웠다.
4. 朔長은 品種間에 다소 差異를 보여 Tomcot SP 22가 5.24cm로 가장 길었고 朔幅은 비슷하였으나 순천시가 2.89cm로 가장 짧았으며, 朔重은 朔長, 朔幅의 크기에 따라 品種間에 差異가 많았다.
5. 實棉重 및 繰棉重은 品種에 따라 多少 差異를 보였으며 實棉重이 무거운 品種이 繰棉重도 무거운 傾向으로, 繰棉比率은 Ouall이 26.29%로 가장 낮았다.
6. 朔當 種實數는 品種에 따라 10개 程度의 差異를 보였으며, 100粒重도 1∼4.19g程度의 差異를 보였다.
7. 績債棉은 品種에 따라 큰 差異를 보였으며 서산읍 봉남동이 214kg으로 가장 많았으며 木債棉은 승주군이 51kg으로 제일 적었고 總 收量은 서산읍 봉남동이 311kg으로 가장 많았다.
8. 分散 分析結果로 草長, 結果指數 株當全莖重을 除外한 全 形質에서 有意性이 認定되었다.

다국어 초록 (Multilingual Abstract)

This study aims to examine the growth and yield of each variety of cottons. The experiment was carried out at the experimental field of Chinju National University from May till December 1995.
1. The plant height and the length of stem internode were similar in each variety. The number of fruiting branches showed difference of 2 to 9 between varieties.
2. The days to decrescence of boll tended to be shortened in the variety whose days to flowering are long. The number of flowering per plant was smallest in Tomcot SP 22 variety(46). The number of bolls per plant was largest in Jackson Strain Cottomol (47).
3. Each variety showed similar stem diameters. The total weight was heaviest in Seosan up Bongnamdong variety(510g), and the root weight per plant was heaviest in Insung Hyunsan variety (48g).
4. The boll length showed a little difference between varieties; the largest length was shown in Tomcot EP 22(5.24cm). The boll width was similar; Sooncheonsi variety was narrowest(2.89cm). The boll weight showed a great difference between varieties according to boll length and width.
5. The seed and lint weight per boll and the lint weight per boll showed a little difference between varieties. They seemed to be in direct proportion with each other. The lint percentage per boll was lowest in Quall(26.29%).
6. The number of bolls per plant was different by 10. And the 100grain weight also showed the difference of 1 to 4.19g.
7. Each variety showed a great difference in the picked cotton; Seosanup Bongnamdong variety produced the heaviest picked cotton(214Kg). In the stalk-cut cotton, Seungjugun variety was lightest(51Kg). The total yield was largest in Seosanup Bongnamdong variety(311Kg).
8. Variance analysis showed a significant difference in all of the characters except the plant height, the number of fruiting branches and the number of total weight.
