Aims The main aim of this study was to investigate the response of various physiology indexes,e.g.,chlorophyll index value(stand for the relative content of chlorophyll,SPAD value),net photosynthetic rate(Pn),stomatal conductance(Gs),and root shoot ratio(R/S) in two genotypes of maize(Zea mays) to NH3 concentration enrichment.Methods We grew maize on Hoagland solution in PVC pots in open top chambers(OTCs).The experiment was a split-split plot design,which main treatments were two NH3 concentrations(10 and ...
