| Abstract: | Leaf colors,key enzymes of nitrogen metabolism,and chloroplast ultrastructure were studied in excessive application of nitrogen fertilizer cultivation on chimera Hosta 'Gold standard'.The results showed that: chlorophyll content significantly increased or decreased in yellow or green leaf area of the chimera in the 2 g/kg of urea fertilizer treatment respectively,and leaf of chimera completely turned green within 28 d.Total N content,activities of nitrate reductase(NR) and glutamate dehydrogenase(GDH) of ch... |
| Keywords: | chimera Hosta 'Gold standard' nitrogen fertilizer leaf color nitrogen metabolism chloroplast ultrastructure |
