“…This finding for P. sativum is consistent with observations in another study using solution culture (Lie, 1969). The impairment of symbiotic N2-fixation at low pH is further supported by lower nodule number and mass, and lower N concentrations in shoots of most species in the present study, and by similar observations for P. sativum (Evans et al, 1980;Jessop and Mahoney, 1982), C. arietinum (Jessop and Mahoney, 1982) and V. faba (Jessop and Mahoney, 1982;Schubert et al, 1990) in other studies. Nodulation and/or N concentrations in L. ochrus, V. ervilia and L. pilosus were also reduced at low pH, although shoot growth of these species was relatively tolerant of solution pH.…”

Defining plant adaptation to soil conditions is critical for the successful introduction of grain legume species into farming systems. This nutrient solution study examined the effects of pH (4, 5, 6, 7 and 8) and bicarbonate (5 mM KHCO3) on the growth and nodulation of 14 grain legume species supplied with N or reliant on N2-fixation. Species included Pisum sativum L., Cicer arietinum L., Lens culinaris Med., and a range of Lupinus, Vicia and Lathyrus species.Species differed greatly in response to solution pH. For both N-fertilized and N2-fixing plants, shoot growth of L. culinaris was very sensitive to low pH (pH < 7), whereas shoot growth ofLupinus angustifolius L. and Lupinus albus L. was sensitive to higher pH (pH > 6). Other species had a broader optimal pH range for growth when supplied with N, but were generally sensitive to low pH (pH < 7 for C. arietinum and Vicia sativa L., pH < 6 for P. sativum, Vicia faba L., Lathyrus sativus L. and Lathyrus eicera L., and pH < 5 for Vicia benghalens& L. and VicM narbonensis L.) when reliant on N2-fixation. For these other species, symbiotic Ne-fixation appeared to be more sensitive than host plant growth to low pH. This finding was supported by lower nodule numbers and mass, and lower N concentrations in shoots of sensitive species at low pH relative to higher pH. For L. culinaris, nodule numbers and mass were relatively unaffected by pH 5-8, N concentrations in shoots were high at low pH and plants developed symptoms relating to H + toxicity at pH as high as 7. These results indicate that host plant growth of L. eulinaris is more sensitive to low pH than the Rh&obium symbiosis. For L. albus and L. angustifolius, both host plant growth and symbiotic N2-fixation appeared to be equally sensitive to pH _> 6. Lupinus pilosus Murr. was more tolerant of high pH than the other Lupinus species. At pH 4, two genotypes of C. arietinum had better early nodulation than other species. Vicia ervilia L. nodulated poorly at all levels of solution pH, indicating that the commercial Group E inoculum (Rhizobium leguminosurum bv. viceae SU303) may not be effective for this species in solution culture.Addition of bicarbonate decreased shoot growth, nodulation and N concentrations in shoots of most species. Early nodulation (nodule number) ofLathyrus ochrus (L.) DC was not affected by the bicarbonate treatment.Abbreviations: MES-2-(N-morpholino)ethane-sulfonic acid, TES-N-tris(hydroxymethyl)methyl-2-aminoethane-sulfonic acid.

“…In the present study also, Nz-fixing P sativum had a lower optimum pH (6-8) than L. culinaris. Jessop and Mahoney (1982) observed under controlled conditions that growth of nodulated P sativum, V. faba and C. arietinum was decreased at pH < 6.0 (in water), but that growth ofC. arietinum was less affected by low soil pH than that of the other species.…”

“…The results of the present experiments suggest that while external pH remains above 4.5-5.0, toxicity is avoided. Indeed, pH's of 5-7 are unfavourable for lupins, which grow optimally in more acidic media than other grain legumes (Jessop and Mahoney, 1982). In soils such as those used in the field assessment of these cultivars ( p H > 7 ) , NH 4 might be an ideal source of N. The acidifying effect of NH 4 uptake in an alkaline, wellbuffered soil would be favourable, whereas it is not compatible with unbuffered, acidic sands where soil pH often falls below 4 after NH 4 application (Jarvis and Robson, 1983).…”

“…On the alkaline clay loams which have been the subject of our earlier investigations (Atwell, 1990a; there is a predominance of nitrate (NO 3) over ammonium (NH 4). However, lupin cultivars which take up nitrogen in the form of NH 4 would be expected to enhance proton extrusion (Jarvis and Robson, 1983), thereby mitigating the well-documented effects of high soil pH on lupins (Jessop and Mahoney, 1982). There are clear differences in the affinity of plant species for NH4 and NO 3 with some evidence that species from acid soils rich in NH4 have a greater affinity for NH 4 as a nitrogen source (Rorison et al, 1983).…”

A b s t r a c t • H +Two cultivars of Lupinus angustifolius L. were grown in a glasshouse in solutions containing N O ; , N 4 o r N H 4 N O 3 with a total nitrogen concentration of 2.8 M m -3 in each treatment. One cultivar chosen (75A-258) was relatively tolerant to alkaline soils whereas the other (Yandee) was intolerant to alkalinity. Controlled experiments were used to assess the impact of cationic vs. anionic forms of nitrogen on the relative performance of these cultivars. Relative growth rates (dry weight basis) were not significantly different between the two cultivars when grown in the presence of NO~, NH 4 or N H 4 N O 3. However, when NO 3 was supplied, there was a modest decline in relative growth rates in both cultivars over time. When plants grown on the three sources of nitrogen for 9 days were subsequently supplied w i t h 15NHnNO 3 o r NH145NO3 for 30 h, NH2 uptake was generally twice as fast as NO 3 uptake, even for plants grown in the presence of NO 3. Low rates of NO 3 uptake accounted for the decrease in growth rates over time when plants were grown in the presence of NO 3 . It is concluded that the more rapid growth of 75A-258 than Yandee in alkaline conditions was not due to preferential uptake of NH 4 and acidification of the external medium. In support of this view, acidification of the root medium was not significantly different between cultivars when NH 4 was the sole nitrogen source.

“…Decreased nodule number associated with increasing pH has been reported in L. angustifolius and L. albus grown in solutions containing bicarbonate (Bertoni et al, 1992;Tang and Thomson, 1996), in L. luteus grown from lime-pelleted inoculated seeds (Parker and Oakley, 1965) and in L. angustifolius grown in a limed sand of pH above 7 (1:5, soil:water) (Jessop and Mahoney, 1982). In nutrient solution, nodulation of Lupinus species was sensitive to high pH whereas that other legumes was sensitive to low pH (Tang and Robson, 1993a;Tang and Thomson, 1996).…”

Interactions Between High pH and Iron Supply on Nodulation and Iron Nutrition of Lupinus albus L. Genotypes Differing in Sensitivity to Iron Deficiency

et al. 2006

Poor growth of white lupin (Lupinus albus L.) on alkaline soils may result from its sensitivity to iron deficiency and poor nodulation. This study examined interactive effects of iron supply and high pH on the growth and nodulation of three genotypes differing in their sensitivity to iron deficiency. Three genotypes (P27486, Ultra and WTD180) were grown for 17 days in buffered solutions with Fe supply of 0.2, 2 and 20 lM. Solution pH was adjusted to 5.2, 6.5 or 7.5. Plant growth, nodulation and nutrient concentrations in plants were measured. Decreasing Fe supply decreased chlorophyll concentration in young leaves by up to 92%. Increasing pH decreased chlorophyll concentration by an average of 40% at pH 6.5 and by 47% at pH 7.5. The decrease of chlorophyll was less obvious in P27485 than in Ultra or WTD180. Shoot biomass was reduced by up to 18% by Fe deficiency, with such decrease being less for P27486. Increasing pH exacerbated the effect of Fe deficiency on shoot biomass only of Ultra. Decreasing Fe supply decreased nodule number by an average of 54%, and increasing pH decreased nodule number by 80%. P27486 formed the greatest number of nodules while WTD180 the least. P27486 had high Fe uptake and low internal requirement. Irrespective of genotype, leaf chlorosis positively correlated with cluster root formation. The results suggest that a combination of Fe deficiency and high pH impaired nodulation in L. albus, and that selection of genotypes for both tolerance of iron deficiency and good nodulation at high pH is important for a successful lupin crop on alkaline soils.
