“…This view is supported by the fact that increasing available fertilizer phosphorus frequently increases N 2 fixation by Rhizobium in the absence of mycorrhizae. It is also thought that the plant-Rhizobium system benefits from the presence of arbuscular mycorrhizae because the mycorrhizae correct not only P deficiency but also any nutrient deficiency in the plant that might be limiting to the Rhizobium (Pacovsky 1986 ;O'Hara et al 1988). Increased mineral nutrient levels in the plant would not only benefit Rhizobium directly, but would also lead to increased photosynthesis, making a greater proportion of photosynthates available to the Rhizobium nodules (Pang and Paul 1980 ;Harris et al 1985).…”

G . A ND R AD E, F .A .A . M. DE L EI J A N D J .M . LY NC H . 1998. Using undisturbed sandy loam soil cores heavily infested with mycorrhizae, the effects of the antibiotic-producing Pseudomonas fluorescens strain F113 and its non-antibiotic derivative Ps. fluorescens F113G22 on nodulation by introduced and indigenous Rhizobium were studied. Furthermore, the effects of the different microbial inocula on the colonization of the pea roots by mycorrhizae were studied. It was found that Ps. fluorescens F113 enhanced nodulation by Rhizobium fourfold, while the nodules produced were much larger and strongly pigmented (pink) compared with those in other treatments. The proportion of roots colonized by arbuscular mycorrhizae was not significantly affected by the different treatments.

“…The amount of nitrogen fixed varies with the strain of Rhizobium, the plant species and environmental conditions. Rhizobium requires phosphorus for its growth and survival in soil, Rhizosphere colonization, infection and nodule development and energy transformation during Nitrogen fixation in root nodules (Hara et al, 1988).…”

“…P concentrations in the seedlings Figure 6. Leghemoglobin (Lb) concentration of soybean grown at T 0 , T 1 and T 2 seedlings and P 0 and P 30 levels in the 5 th week; letters on the top of the bars indicate significant differences at 5% level were higher than required P level for rhizobia growth and survival (0.5 µM P) (O'Hara et al 1988). This showed that seedlings contained enough P to establish nodules, and were thus comparable with the seeds that reserved P as reported previously (Valverde and Wall 1999).…”

The effect of three seedling treatments: T 0 , normal germination; T 1 , cotyledons removed; T 2 , cotyledons removed 5 days earlier than in T 1 ; and two phosphorus levels (P 0 and P 30 ) on nodulation and nodule function in soybean [Glycine max (L.) Merr.] were investigated in nutrient solution culture. The number of nodules formed at P 0 was in the order T 2 > T 0 > T 1 , but it was T 0 > T 2 > T 1 at P 30 . Nodule dry weight per plant had the same tendency as the nodule number. Nodule size (dry weight per nodule) in seedlings ranged from 0.601 to 1.089 mg in the order T 0 > T 1 > T 2 , regardless of P level. For example, nodule size in T 0 was larger by 86% and 52% than T 2 at P 0 and P 30 , respectively. Furthermore, regardless of P level, a specific acetylene reduction activity (ARA, µM C 2 H 4 /h/g nodule) increased with P content in seedlings, but no significant difference was found (P < 0.05). Leghemoglobin (Lb) content was not significantly affected by P level; however, seedlings (T 0 and T 1 ) significantly affected the Lb content per unit plant biomass (P < 0.05). All these results suggest that seedling P content plays a key role in nodulation and nodule function of soybean.
