| Abstract:
Gamma linolenic acid (GLA) has been recognized as a beneficial treatment for a variety of human ailments including high blood pressure, cardiovascular disease, skin disorders, and diabetic neuropathy. Oenothera biennis has been the most widely used species of evening primrose to produce GLA. Over a period of two years, native accessions of O. elata, O. jamesii and O. rhombipetala were produced as transplants in a greenhouse and mechanically transplanted to the field using three different plant spacings. Plots were harvested and analyzed to determine seed yield, oil content and GLA level. In the two years of this study, seed yield, oil content and GLA level were significantly impacted by plant spacing treatments. Generally, the higher plant populations gave the best results. | |
