大豆 및 강낭콩내 微量元素의 濃度 및 分布에 미치는 DTPA의 影響 = Effects of DTPA on Microelements in Soybean and Bush Bean

국문 초록 (Abstract)

HA(Fe-chlorosis reaistant)와 Pl(Fe·chlorosis sensitive) 大豆가 Yolo loam 土壤에서 DTPA를 加하거나 안한 곳에서 자라게 했다.
本 硏究의 主目的은 微量元素의 轉移를 增加시키는 chelating agent의 역할을 評價하기 爲함이다. 즉 微量元素의 濃度를 增加시키는 여러 處理에서 이들 微量元素의 葉 및 莖內 分布를 比較하기 爲한 것이다.
한 處理區로서 土壤에 S를 使用하여 酸性土壞으로 유도시켰다.
植物의 反應과 生産量을 조사하여 Fe, Mn, Zn, Cu, Al, Ti, Co, Ni, Sn, Pb 및 Mo등의 葉 및 莖內 含量을 emission spectrography에 의해 定量하였다.
S는 葉內 Mn, Zn, Cu, Co, Ni, Sn 및 Pb 含量을 增加시켰다.
土壤內 50ppm DTPA는 Fe, Zn, Cu, Co, Ni및 Mo의 葉內 含量을 增加시켰다. DTPA는 Fe, Zn, Cu, Co, Ni, Mo 등의 莖內 含量에 比해 葉內 含量의 比를 더 增加 시켰다.
DTPA는 土壞 pH 6과 8.5에서 강남콩의 줄기보다도 葉內 Fe, Zn,Cu, Ni의 농도를 增加시켰다.
Pl 大豆는 HA 大豆보다 大部分의 金屬을 적게 포함하는 경향이 있었다.
本 論文은 美國UCLA에서 Dr. Arthur Wallace의 도움으로 이루어진 것이다.

다국어 초록 (Multilingual Abstract)

Hawkeye(Fe-chlorosis resistant) and PI54619-5-1(Fe-chlorosis sensitive) soybeans were grown with and without DTPA(diethylene triamine pentaacetic acid) in Yolo loam soil. The major purpose of the study was to compare leaf-stem distribution of microelements for different treatments which increase concentrations of micro-elements in plants to evaluate the role of the chelating agent in increasing translocation of the microelements.
Plant responses and yields were recorded and Fe, Mn, Zn, Cu, Al, Co, N, Sn, Pb and Mo contents of leaves and stems were determined by emission spectrography.
Sulfur(soil pH4) increased leaf concentrations of Mn, Zn, Cu, CO, Ni, Sn and Pb.
DTPA, particularly at 50ppm in soil, increased leaf concentrations of Fe, Mn, Zn, Cu, CO, Ni and Mo. It increased Ti in leaves for the PI54619-5-1 soybeans only. DTPA increased the ratios of the concentration in leaves to that in stems for
Fe, Zn, Cu, Al, Ti, CO, Ni and Mo.
Sulfur which increased the microelement concentration in both leaves and stems did not have this effect.
DTPA increased the ratio at soil pH 6 and 8.5 in leaves to that in stems of the bush bean plants for Fe, Zn, Cu, Ni, but to a lesser extent in bush beans than in soybeans. PI 54619-5-1 soyteans tended to contain less of most of the metals than did Hawkeye soybeans.
