Biochemical changes during the induction of mineral stress in plants of bell pepper cultivated in fertigation system
The greenhouse production associated with the fertigation management, have established in Brazil as economical alternative for several horticultural species. With this strategy this study had as aim to evaluate possible impacts in the metabolism of plants of bell pepper (Capsicumannuum L.; cv Elisa)...
