Interactions among hormones effects on developmental process. There is much evidence indicating interactions between ABA and ethylene signaling cascades. BABA is a non-protein amino acid. It has been shown that BABA induces stress-induced morphogenic response. BABA activates some ABA signaling intermediate and also alters the expression level of some genes implicated in signaling by ethylene. The aim of this study was to examine whether BABA alters seed germination and some growth parameters via involvement of ABA and/or ethylene signaling or not. In this study, it is shown that BABA had no significant effect on seed germination of canola but in ABA and CoCl2 treated seeds, germination was reduced compare to the control. ABA inhibited root growth more than BABA. Combined use of ABA and BABA treatment, had an additional inhibitory effect on shoot and root growth. Application of Cobalt chloride as an inhibitor of ethylene synthesis, increased root length but decreased shoot length. Use CoCl2 with BABA improved significantly reduction caused by BABA. The results demonstrated that the effects of BABA on seed germination and growth parameters involves an ABA /ethylene-independent function
