Oils from seeds produced at three locations on plants of Nugget (Brassica napus L.) and Echo (B. campestris L.) rapeseed, grown in field plots and a controlled environment room, were analyzed for their fatty acid composition. The fatty acid composition of oil from field-produced seed was not affected by the location of the seed on the plant. However, in the controlled environment room the effect of seed position was significant. Nugget seed from the lowest raceme contained seed oil with significantly higher linolenic acid and lower erucic acid than seed produced on the main raceme. Echo seed from the lowest pods on the main raceme contained significantly less palmitic acid than seeds from the lowest pods on the lowest raceme. Nugget seed grown in the controlled environment room had a significantly higher content of palmitic, stearic and oleic acids, and significantly lower levels of linoleic, linolenic and erucic acids than Nugget field-produced seed. The fatty acid composition of Echo seed oil produced under the two environments did not differ significantly. Single pod samples should be restricted to the same position on each plant to reduce the position effect on fatty acid composition. This and previous studies indicate that comparisons of fatty acid values for plants grown at different locations should be avoided.

Brassica Napus L

Plants of rape (Brassica napus L. ’Erglu’) were grown under controlled greenhouse conditions. The growth and composition of pods (hulls) and seeds was followed from the day when flowering took place to maturity. Pod development could be divided into three stages. In the first stage hull growth was more rapid than seed growth. Nitrogen accumulation in hulls occurred at a maximum and seeds were characterized by a high protein content but a low oil content and a fatty acid composition similar to that of photosynthetic tissue. During the second phase dry matter of hulls began to decrease, nitrogen was exported and the rates of seed dry matter accumulation grew to a maximum. At the same time the protein content of seeds declined while oil content increased rapidly. The fatty acid composition had reached the final condition. In the third stage hulls continued to lose dry matter and the rates of seed dry matter accumulation decreased dramatically. Pod growth was affected by the location of the pod on the plant. The individual seed weight and the fatty acid compvsition at 16 days after flowering indicated an accelerated development of seeds from axillary branches. Pods from the main branch generally produced the largest amount of seed dry matter. From these results the ideal high-yielding rape plant was characterized.
