땅콩의 品種別, 播種期 및 開花期에 따른 生態反應에 관한 硏究 : Arachis Hypogaea L. = Studies on the Ecological Responses to Cultivars, Seeding Date and Plantin Flowers of Peanut

국문 초록 (Abstract)

栽培環境의 變化에 따른 落花生 品種別 開花의 生態反應에 對하여 硏究하기 위하여 安城農業專門大學 實驗圃場에서 實施하였다. 그 結果를 要約하면 다음과 같다.
1. 땅콩의 開花까지의 日數는 供試된 各 品種 共히 4月20日 및 5月10日 播種區에서는 65日, 5月 30日 播種區에서는 36日로 晩播의 경우 短縮率이 컸다.
2. 땅콩의 開花最盛期는 8月10∼8月20日頃으로 1株當 開花數는 300∼500個의 範圍에 分布하였다.
3. 땅콩의 分枝別 開花數는 第1分枝∼第5分枝까지의 開花數가 總 開花數의 80%, 以上을 차지하며 品種 및 播種期에 關係없이 下位分枝에서 많고 上位分枝로 갈수록 적었다.
4. 땅콩의 株當 10分枝의 品種別 開花最盛期는 匍匐型이 8月 11日∼8月20日, 半立型이 8月11日∼8月15日, 直立型이 7月26日∼8月5日頃이며, 株當 總 開花數는 匍匐型이 430∼545個, 半立型이 310∼318個, 直立型이 260∼315個 程度이였다.
5. 땅콩의 株當 10分枝의 播種期別 開花最盛期에서 4月20日 播種區는 7月26日∼8月15日, 5月10日 播種區는 8月1日∼8月20日, 5月30日 播種區는 8月16日∼8月25日까지였다.
6. 땅콩의 株當 10分枝의 1日平均 開花數는 適期 播種의 경우 匍匐型이 6.7∼7.4個, 半立型 4.3個, 葉落花生 4.0個, 水原15號 5.5個이었다.
7. 結莢率은 24∼28% 程度였으며 播種期가 遲延됨에 따라 減少하고 分枝別 結莢率은 第1分枝부터 第5分枝까지는 20∼50%였으나 그 以上 分枝에서는 直線的으로 低下되었다.

These studies were carried out to study on ecological reaction to flowering of peanut variety depend on cultural environment at the experiment farm of An Sung Agricultural technical College.
The result obtained are summarized as follows.
1. The period from seeding to blooming were 65 in the plots planted on April 20 and May 10 while those on May 30 were 36, The number of days from sowing to flowering decreased remarkably as seeding date was delayed.
2. It was recognized that the zenith of flowering is from 10 to 20 of August for the number of flowers per seed is from 300 to 500 individual.
3. Number of flowers from ist to 5th branches was amounted to 80% of total. The flowers were numerous in lower branches and less in upper branches regardless of cultivars of seeding date.
4. The blooming period of the branches per plant was from 11 to 20 of August for the runner type cultivars; from 11 to 15 of August for Semi-runner type; from July 26 to August 5 for the Spanish type. Total number of flowers per plant was 430-545 for runner, 310-318 for Semi-runner, and 260-315 for Spanish type.
5. The blooming period was from July 20 to August 15 for the plots sown on April 20, from 10 to 20 of August for those seeded on May 10.
6. Average number of flowers that bloom in a day for the ten branches per plant was 6.4-7.4 in runner, 4.3 in Semi-runner 5.5 in Suweon 15 and 4.0 in leaf peanut for optimum sowing date.
7. Podding ratio formed from 24% to 28% et reduced in case of later seeing, podding ratio per branch beared from first to fifth branch formed 20% to 50% but decreased from sixth branch.
