Abstract
By the GC,HPLC,physiological and biochemical indices,the resistant and signal substances which induced by spraying copper against potato virus Y-vein necrosis strain(PVYN) were studied.The results showed that when treated with copper at the concentration of 0.8mg.L-1,the symptom appearing was postponed,vein necrosis degree was lightened,the disease index and the content of virus sharply down.The content of proline and soluble sugar in tobacco leaves were increased,and the leakage rate of electrolyte restrained.The content of salicylic acid(SA) reached the high peak at the 15th day after inoculation,which 1.3 times than that of inoculation control.The release of ethylene(ETH) was much higher than that of control in a short time.At the 12th day,ETH released from control was sharply increased,which was much higher than that of copper treatment,because the signal pathway in tobacco leaves was activated when treated with copper solution in early time.In conclusion spraying copper solution could induce tobacco plant resistance to PVYN and activate the signal pathway.Those indicated that the induced resistance was promoted and the symptom was lighten.
