文摘

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 M_r; however, only hexanoic acid (C₆) and C₉ acid induced a strong appearance of PAs bound to substances of high M_r. 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.
