Technical Abstract: Acyl group competition was studied during seed maturity in Lesquerella fendleri seeds. Flowers of individual lesquerella plants were tagged while growing in the field at two Arizona locations. The age of the seeds in each pod was expressed as the number of days between opening of the flower and harvest of the pod (DAF). Seeds were harvested at 4-day intervals from 15 to 71 DAF. Seed samples were stored at -80 degrees C following collection. After seed collections were completed, samples were arranged in three replications of a completely randomized design and analyzed on a gas chromatograph. Seed weight, lesquerolic hydroxy fatty acid, and other prevalent fatty acids were evaluated. The objective of this study was to relate the age of the seed to the optimum harvest date.
