Effect of freezing on total lipids and fatty acid composition of mustard seeds (Brassica juncea L.).

摘要

Pot experiments were conducted to assess the effects of exposing B. juncea cv. RH-30 to -3+- 0.5degC for 2 h at the vegetative or reproductive stage (28 and 35 days after sowing and flowering, respectively) on seed total lipid and fatty acid contentsat harvest. Results indicated that lipid and fatty acid contents were unaffected by freezing at the vegetative stage. However, lipid content was reduced when plants were frozen at the reproductive stage, while erucic acid levels were reduced and linoleicacid levels increased.
