Abstract
Oilseed rape (Brassica napus L) is one of the most important oil crops for food as well as for bio-fuel. The growth environment, especially availability of nutrient element plays a key role for the yield of oil production. In order to study the relation between the nutrient absorption manner and the quality of the oil, we measured the amount of each element absorbed during the developmental stage of B. napus (Westar), using ICP-AES and ion chromatography.
When hydro-culture was employed, the absorption amount of the major elements (N, P, S, Mg, Ca) per fresh weight was decreased during the development. The absorption of minor elements (Fe, Mn, Zn, B, Cu) per fresh weight showed characteristic curves around flowering stage. The element absorption manner was also measured for the plants grown in field.
To study the absorption manner of the elements more in detail, real-time RI imaging system, we developed, was used applying 32P labeled phosphate. The real-time uptake and distribution manner of the phosphate was visualized for both plants when grown in hydro-culture as well as in soil.
