Sicklepod Fatty Acid response to photoperiod.

Sicklepod (Cassia obtusifolia L.) grew taller and heavier in a 12-hour photoperiod than in photoperiods longer or shorter. Total vegetative fatty acid content was maximal under 14-hour photoperiods as were unsaturated and branched chain fatty acids. Odd-numbered fatty acid content was highest under 16-hour photoperiods, and evennumbered fatty acids tended to be more concentrated under 14-hour photoperiods. Age of plant influenced total vegetative fatty acid content.
