Study on Accumulation Pattern of Fatty Acids during Seed Development of Rape Seed Cultivars with High or Low Erucic Acid

Taking two rape seed (Brassica napus) cultivars (Mianyou 14 with low erucic acid,and Mianyou 322 with high erucic acid) as experimental materials,this paper studied the accumulation patterns of main fatty acids in the maturation process of oilseed rape grains.The results showed that:between the two varieties,the accumulation patterns of palmitic acid,linoleic acid and linolenic acid in seeds were basically the same,and their contents in low-erucic-acid variety were much higher than those in high-erucic-acid variety.However,the accumulation patterns of oleic acid,arachidonic acid and erucic acid had significant differences between the two varieties,and their contents in high-erucic-acid variety were higher than those in low-erucic-acid variety.
