Lipid components of mustard seeds (Brassica juncea L.) as influenced by cadmium levels.
In a pot experiment the soil application of different levels of Cd2+ (0, 10, 20, 30, 40 and 60 micrograms g-1 soil) affected the lipid components of mustard seeds (Brassica juncea L. Cv. RH-30) markedly. Total lipids declined with the Cd2+ levels regularly while phospho and glycolipids increased only at higher levels. Fatty acids profile of total, neutral and polar lipid fractions were affected considerably. Erucic acid in total and neutral lipids was observed to increase while it decreased in polar lipids with Cd2+ as compared to control. On the other hand palmitic, oleic and linoleic acids had reverse trend. Cadmium concentration increased consistently with increasing levels of Cd2+. Plant dry weight was also decreased significantly with Cd2+ levels.
