| 英文摘要 | Phosphorus (p) is necessary for growth and nitrogen fixation, and thus its deficiency is a major factor limiting legume production in most agricultural soils. the effect of phosphorus supply on nodule development and its role in soybeans (glycine max l.) was studied in a nutrient solution. plants were inoculated with bradyrhizobium japonicum and grown for 35 days in a glasshouse at a day and night temperature of 25 degrees c and 15 degrees c, respectively. although increasing p supply increased the concentrations of p and n in the shoots and roots, the external p supply did not significantly affect the p concentration in the nodules, and the n fixed per unit nodule biomass decreased with increasing p supply. the nitrogen content in the shoots correlated well with the p content (r = 0.92**). at an inoculation level of 10(2) cells ml(-1), the p supply did not affect the number of nodules; however, at inoculation levels of 10(3.5) and 10(5) cells ml(-1), increasing p supply increased both the number and size of nodules. irrespective of the inoculation level, increasing p supply increased the nodule biomass relative to the biomass of the host plant. it is suggested that the p deficiency specifically inhibited the nodule development and thereby the total n-2 fixation. |
