Abstract: | Soybean suspension cultures were grown for 24 weeks in the absence of plant growth regulators and in the presence of 1 ppm levels each of an auxin (indole-3-butyric acid), a cytokinin (kinetin) and a gibberellin (gibberellic acid), individually and in all possible combinations. Cells grown in the presence of the auxin with and without gibberellin contained relatively greater amounts of palmitic and smaller amounts of polyunsaturated acids than did cells grown under other regimens. The combination of cytokinin and gibberellin caused a higher proportion of linoleic and a lower proportion of linolenic acids than in cells of the other groups. Neither of these regulators by itself produced the effect, and addition of auxin to the other two diminished the effect. |
