摘要: The transport of salicylic acid (SA) was studied in cucumber (Cucumis sativus L.) using 14C-labeled benzoic that injected the cotyledons at time inoculation. Primary inoculation with tobacco necrosis virus (TNV) on led to an induction systemic resistance first primary leaf above cotyledon against Colletotrichum lagenarium as early 3 d after [14C]SA detected phloem or 2 TNV inoculation, whereas [14C]benzoic not during cotyledons, indicating from cotyledon. In 1, specific activity decreased between 1.7 and 8.6 times compared that, addition transport, 1 also produced more SA. amount SA transported infection 9 160 higher than uninfected control plants. Thus, can be before development acquired resistance, accumulation results both synthesis 1.
