Leaf quality of Ginkgo biloba at the late growing stage with different NO3- -N and NH4+ -N combinations

Abstract: To find how to improve the leaf quality of Ginkgo biloba (ginkgo) at the late growing stage by fertilization , leaf quality of ginkgo at the late growing stage with different combinations of NO3- -N and NH4+ -N was studied.The test resources were two-year-old ginkgo seedlings in the greenhouse of Nanjing Forestry University , transplanted and grown in pot cultures with 1.00 gpot-1 N .A CRD experimental design was established with 3 replications and treatments of NO3- -N and NH4+ -N ratios 0∶0 (the control), 0∶100 , 25∶75 , 50∶50 .75∶25 and 100∶0 .Results showed that root vigor (RV) , nitrate reductase activity (NR)and NO3- -N of the leaf , was significantly greater with NO3- -N (P 0.01).Also soluble protein (SP), free amino acid (AA) and total flavone (TF) with treatments of NO3- -N and NH4+ -N ratios 50∶50 and 75∶25 were significantly greater (P 0.01) than others, soluble sugar (SS) and reducing sugar (RS)with treatment of NO3- -N and NH4+ -N ratios 50∶50 were significantly greater (P 0.01) than others .As the proportion of NH4+ -N increased and NO3- -N decreased a little ,NO3- -N in the G.biloba leaf decreased with SP, free AA , SS , RS , and TF increasing .For NO3- -N , SP , free AA , SS , RS , and TF , the best NO3- -N∶NH4+ -N were 75∶25 and 50∶50 .[ Ch , 6 fig .2 tab .12 ref .]
