Young Seed

Castor seeds were collected at 3- and 6-day intervals after blossoming until maturity. The seeds were analyzed for protein and oil content and the fatty acid composition of the oil was determined by gas–liquid chromatography. Oil formation began 21 days after blossoming and two-thirds of the oil was synthesized in the next 20 days; the remaining one-third was formed in the last 20-day period. Protein synthesis occurred over a longer period of time but was accelerated during the middle 20-day period.Ricinoleic acid, the characteristic component of castor oil, was not present in the very young seed, but appeared when the seed was 12 days old and represented 90% of the fatty acids when the seed was 36 days old. After this time the fatty acid composition of the oil remained constant and characteristic. In the intervening 24-day period, the amount of ricinoleic acid was lower than normal. The amount of each fatty acid component, expressed on a per seed basis, increased over the entire period of development and there was no evidence of substantial conversion of oleic or linoleic acid to ricinoleic acid.

Abstract This study aimed to investigate the effects of plant growth regulators in callus cell culture on the oil content and fatty acid composition of the castor bean (Ricinus communis L.). Ricinus communis L. are valued for its oil and the performance of oil is closely related to its fatty acid composition. Thus, producing oil in vitro with favored fatty acid profiles is a promising research area and may also offer industrial opportunities. In line with this, the total amount of fat and the fatty acid composition of the samples, which were endosperm and calli obtained by treatment of various doses of plant growth regulators were determined. Results showed that the type and amount of the plant growth regulator used in the media affect the fatty acid composition. In detail, the biggest change was shown by Indole-3-Acetic Acid (IAA), in general, using the plant growth regulators at 5 mgL-1, instead of 20 mgL-1, was found to have induced larger differentiations. The effect of a natural plant growth regulator (IAA) on fatty acid profiles was larger than the synthetic ones (NAA, 1-Naphthaleneacetic acid, and 2,4 D, 2,4-Dichlorophenoxyacetic acid). The media containing 5 mgL-1 of NAA, 20 mgL-1 of NAA, 20 mgL-1 of 2,4 D, or 5 mgL-1 of 2,4 D gave similar results.
