Fatty Acid Accumulation in Maturing Flaxseeds as Influenced by Environment 1

AUTOR(ES)
RESUMO

The effects of temperature and light on boll and shoot maturity and on the accumulation of fatty acids in developing seeds of flax (Linum usitatissimum L.) were determined in controlled environments. Palmitic and linoleic acids decreased but linolenic increased in percent as seed formation progressed. In the same period, oleic acid increased in percent in 1 variety and decreased in another. Increased temperatures hastened these changes and resulted in decreased iodine value of the oil at maturity.
