Short-chain saturated fatty acids (SCSFA), ranging from pentanoic (C5) to decanoic acid (C10), when added at micromolar concentrations to the germination medium of chick-pea seeds, did not significantly affect radicle emergence, although fresh weight diminished. Only heptanoic acid (C7) and octanoic acid (C8) stimulated ethylene production and free spermidine and spermine content, whereas putrescine reached a maximum with nonanoic acid (C9). All the SCSFA tested increased the polyamines (PAs) bound to substances of low Mr; however, only hexanoic acid (C6) and C9 acid induced a strong appearance of PAs bound to substances of high Mr. Proline synthesis was stimulated in the presence of C7 acid and C9 acid, but values lower than control were obtained with the other SCSFA studied.
