مقايسه روش هاي مايه زني بلال هاي ذرت با قارچ FUSARIUM MONILIFORME

Four methods of maize ear inoculation (silk channel injection, silk spray, toothpick, nail punch) and one control (without inoculation), and three opaque-2 maize lines, has been compared lor determination of susceptibility to ear rot, in 1997, in Karaj. A randomized complete block design in split plot arrengment (methods as main and lines as subplots) with three replications was used. According to the results, effects of methods were significant at 1% level of probability for both disease incidence and severity, but, the effects of lines were significant only for disease severity.Comparing the methods and method X line interaction, showed that the disease severity should by better index for determination of susceptible germplasms and effective method of inoculation when compared to disease incidence. Nail punch method provided the highest disease severity and was much better than others for determination of susceptible lines to ear rot.
