Abstract
The effects of methyl jasmonate (MJ) and abscisic acid (ABA) on some physiological processes of rice were compared. MJ exhibited ABA-like effects by promoting senescence of detached leaves, by inducing acid phosphatase activity of detached leaves, by inhibiting ethylene production and shoot growth of seedlings, as well as inhibiting callus formation from anthers. However, MJ and ABA had opposite effects on 1-aminocyclopropane-1-carboxylic acid-dependent ethylene production in detached leaves. The regeneration ability of anther-derived callus was inhibited by MJ but not by ABA. MJ but not ABA markedly induced peroxidase activity in senescing detached leaves. It is concluded that not all physiological processes of rice affected by MJ are similar to those by ABA.
