Stevia(Stevia rebaudiana BERTONI)의 栽植密度가生育및收量에 미치는影響

국문 초록 (Abstract)

本試驗은 砂壤土에 栽植密度를 달리하여 Stevia 栽培에 있어서 生育및 收量에 미치는 影響을 究明 코저 實施한바 그結果를 다음과 같이 要約한다.
1.本試驗에서는 試驗團50㎝×15㎝및 60㎝×10㎝가 收量이 우수하였다.
2.草長및 分植數는 分植數가 增加됨에따라 增加하는 傾向이나 一定限度를 넘으면 오히려 減少 되었다.
3.主莖長및 乾葉重에 있어서 Stevia는 栽植密度가 넓은 것에서 좁은것 보다 작았으며 基他 栽培는 비슷하엿으나 그 以後 넓은區에서는
급격히 減少 하였다.
4.收量과 生育의 相關에서 主莖長,分枝長,生體重,乾葉重에서 收量과 높은 正의 相關이 있었으며 其他 形質의 相關은 거의 認定할수 없었으며 栽植密度에 따른 相關의 差異가 認定되었다.

The expeniment was was carried out to control the effect of planting density on growth, fruiting and yield of stevia plant in sandy loam soil, the results are summarized as follows
1. In this experiment, the planting density 50㎝ × 15㎝ and 60㎝ × 10㎝, showed the most vigorous yield
2. Growing height and branch of the plantlet increased in accordance with the increase of stems, but decreased when exceeded suitable amount of stems
3. Length of main stem and dry leave weight of stevia were exceptionally decreased among the largely - planting - density groups when compared to narrow ones while the other varieties were tend to be same between the indicated planting groups, But, after - all, these two traits were rapidily decreased in largerly - planting - density - groups.
4. Highly significant positive correlations were showed between the yield and the growth components such as dry weight main stem and sub - ones.
However, the other characters were almost not correlated between the above two, the differences of correlation coefficient could be found according to the planting density.
