Resumo
The objective of this research was to evaluate nitrogen, phosforus, potassium, calcium, magnesium, and sulfur contents on shoot dry matter of bean plants cultivars IAC Carioca Arua, IAC Carioca Pyata, IAC Carioca Akyta (resistant to the bacterial wilt), IAC Carioca, and Perola (susceptible to the bacterial wilt) inoculated or not with one isolate of Curtobacterium flaccumfaciens pv. flaccumfaciens. It was observed that all cultivars infected by C. flaccumfaciens pv. flaccumfaciens showed reduction of shoot dry matter and macronutrient contents. However, resistant cultivars had a lower reduction of nitrogen, phosforus, potassium, calcium, and magnesium contents than bacterial wilt suceptible cultivars.
