“…Assessing genotype responses for root biomass in pots or liquid culture (as done here and in most earlier studies) is less reliable, although less expensive, than in tall soil chambers . The observed genotype×soil interaction for nodule number, and the trend of lime-tolerant genotypes towards lower nodulation reduction in ML soil, are consistent with results by Raza et al (2000) and Tang et al (2006). One mechanism for better genotype ability to maintain nodulation in calcareous soils might be the greater capacity for acidifying the rhizosphere, which favors Bradyrhizobium colonization by improving its growing environment and the availability of iron from the plant (Tang et al 2006).…”

“…Genotype×soil interaction for shoot biomass was detected across limed and non-limed soils, or acid and moderately alkaline soils, in most (Liu and Tang 1999;Raza et al 2000;Tang et al 2006) but not all (Kerley et al 2002) earlier studies. Two studies (Liu and Tang 1999;Tang et al 2006) also found genotype×soil interaction for root biomass, unlike here.…”

“…The adaptation of white lupin to calcareous soils might be enhanced by the identification of plant genotypes that are tolerant to these conditions and can be exploited to breed adapted varieties. Various studies Raza et al 2000;Kerley et al 2002) highlighted the adaptation of Egyptian germplasm to moderately calcareous or limed soils, which reflected their adaptation to conditions of their geographic origins. Variation in adaptation to limed or alkaline soils was also reported by Liu and Tang (1999) for commercial varieties and some accessions of indefinite origin.…”

Aims This study aimed to determine whether white lupin adaptation to moderately calcareous soils could be enhanced by lime-tolerant plants and Bradyrhizobium strains. Methods Fourteen landraces from Italy, Morocco and Egypt and some cultivars were grown in moderatelime (ML) and low-lime (LL) soil with each of two inoculants, one commercial and one including three Bradyrhizobium strains well-nodulating under ML soil (isolated from other lupin species). Grain yield and above-ground biomass were assessed in large artificial environments that mimicked field conditions. Shoot, root and nodulation traits at onset of flowering were studied in a pot experiment. Results ML soil severely reduced plant yield, growth and nodulation but increased the harvest index relative to LL. Top-yielding genotypes for grain yield displayed significant rank inversion across soil types (P < 0.05). Limetolerant genotypes reduced their nodulation in ML soil less than limesusceptible ones. Some landraces outperformed the reference lime-tolerant cultivar Giza 1 in ML soil. One Italian landrace had a lime-tolerant response across agricultural locations. The Moroccan inoculant provided greater nodulation, more shoot residues but similar grain yield in ML soil, and less grain and shoot residues in LL soil, compared with the commercial inoculant. Conclusions Lupin adaptation to ML soil can be improved mainly through selection of lime-tolerant plants.

“…Many local landraces of white lupin collected from the farmers in Egypt are screened for the tolerance to the high alkaline soil reaction and proved to be extremely tolerant, although the mechanisms underlying the low uptake of calcium still remain unexplained (Raza et al 2000a). Since anthracnose is the major disease of white lupin in Australia, a search for the potential sources was made.…”

Summary:The genetic resources of legumes (Fabaceae Lindl.) are facing the narrowing the genetic basis of cultivated species, that is bottlenecks of the available gene pools. This is caused mostly by breeding, since it aims at improving yield and quality. The most widely cultivated crops are in a specific danger of losing numerous desirable traits due to a heavy selection pressure preferring usually yield. Using locally cultivated and maintained landraces of the economically most important annual legumes, such as chickpea (Cicer arietinum), lentil (Lens culinaris), grass pea (Lathyrus sativus), white lupin (Lupinus albus) and faba bean (Vicia faba) may assist breeding and various modern crop systems. They preserved numerous desirable traits that may be easily introgressed into modern cultivars and thus improve their performance.

Is pH the key reason why some Lupinus species are sensitive to calcareous soil?

Aims: Previous studies have shown that pH, rather than calcium (Ca), is the main reason why some Lupinus species are sensitive to nutrient solutions mimicking calcareous soils; however, a hydroponic system is quite different from soil systems, and plants may respond differently to these two growing conditions. Thus, studies with Lupinus species grown in calcareous soils are needed. Methods: Two calcicole and two calcifuge species were grown in river sand with different Ca forms and amounts, pH levels, and [bicarbonate (HCO3-)] (which is produced by calcium carbonate (CaCO3)). Leaf symptoms, leaf area, gas exchange, biomass, and root morphology were recorded; whole leaf and root nutrient concentrations were analysed. Results: We observed leaf chlorosis of the youngest leaves under high pH (adjusted by KOH) and high pH + high Ca (representing high [HCO3-], high pH and high Ca) treatments for all Lupinus species. However, after two weeks, leaf chlorosis of all Lupinus species under high pH started to disappear, with calcicole species fully, and calcifuge species only partly recovering. Leaf chlorosis symptoms of calcicole species under high pH + high Ca partly disappeared as well, while those of calcifuge species did not disappear at all. Conclusions: High pH (resulting from either KOH or HCO3-) inhibited root growth, and subsequently uptake of some nutrients and shoot growth of Lupinus species. However, the strong buffering capacity of HCO3is the key factor determining if Lupinus species can survive in calcareous soils. Among all studied Lupinus species, L. pilosus was the most tolerant to high [HCO3-] and/or high pH, followed by L. cosentinii and L. angustifolius, while L. hispanicus was the most sensitive.
