Thebiomass,nitrogen uptake of crops and grain yield were significant correlation to the parameters of soil nitrogen mineralization,such as No,K,No×K,Log(No×K),and NA,all of which could used as predicate index,especially the No×K,and Log(No×K).
THE NFLUENCE OF APPLYING MUTANT STRAIN OF AZOSPIRILLUM BRASILENSE(CWV-22)ON CROP MATTER PRODUCTION AND NITROGEN CIRCULATION Ⅰ.A SAND EXPERIMENT ON THE INFLUENCE oF CWV-22 APPLICATION ON THE GROWTH AND NITROGEN UPTAKE OF WHEAT AND MAIZE
The total dry weight was the highest in 478 with high N efficiency among the five genotypes, relatively lower in Wu312 and Zong31 at low N supply, due to its higher N uptake efficiency, followed by H21, Baici, Zong31 and Wu312 (Fig 1).
The different of N uptake by grain, straw and biomass of aerial part between highest and lowest genotype in N2 treatment are 1 060,0 134 and 1 125 g/kg, respectively, and that in N4 treatment are 0 836,0 154 and 0 954 g/kg,respectively.
Based on this qualified method, we investigated the variations of OsAMT1.1 (one of nitrogen uptake genes) and OsGlt1 (one of nitrogen metabolism genes) expression levels in rice seedlings under conditions of varying nitrogen supply.
Nitrite in all concentrations detrimentally affected the phosphate release and uptake rates, chemical oxygen demand uptake rates, nitrogen uptake rates, as well as multiplication of A.
Impact of low pH and aluminium on nitrogen uptake and metabolism in roots of Lotus japonicus
The effect of low pH and aluminum on nitrogen uptake and metabolism was studied in roots of Lotus japonicus grown in hydroponic cultures.
schachtii infestation initially with a decrease in photosynthesis rate and later with a reduction in nitrogen uptake and chlorophyll concentration.
