“…High temperature has been found to promote the release of phosphoserine, phosphoethanolamine, citrulline, threonine, glycine and ammonia from the root systems of legumes (Ofosu-Budu et al 1992). In the present study, higher amounts of arginine, cystathionine, ethanolamine, histidine, hydroxyproline and ornithine in winter nodules are correlated to protection against low temperature.…”

. 2003. Seasonal changes in protein, amino acid and elemental composition of perennial nodules of beach pea. Can. J. Plant Sci. 83: 507-514. Changes in proteins, amino acids and elements were studied in the perennial nodules of beach pea during winter, summer and fall. Accumulation of total protein content in the nodules increased from mid-summer to early winter and then decreased. Among the total amino acids studied, arginine, cystathionine, ethanolamine, histidine, hydroxyproline, ornithine and proline were found to increase in winter nodules. γ-aminobutyric acid was found to be significantly higher in fall and summer, whereas sarcosine was higher in summer and winter. Large amounts of K followed by Ca were found in almost all nodule tissues. Phosphorus, Al, Si and Cu showed significant variation among different nodule tissues within winter and summer. In the nodular tissue, significantly larger amounts of Na, K and Mg were found in the winter and S in the summer. In both winter and summer, no significant difference could be observed in the distribution of Cl, Mo, Ca, Mn, Fe and Zn among nodule tissues. Irrespective of nodule tissues, the complete nodule showed the following seasonal changes: high K, Ca and Zn in winter; high Cl and Al in summer; high S and Si in fall; high Mn in both winter and summer; high Cu in both winter and fall; high Na, Mg and Fe in both summer and fall; no significant changes in the amounts of P and Mo.

“…In the studies summarized in Table 13, nitrate-N levels in soil immediately following legumes were between 14 and 77 kg N ha -I greater than the levels after non-legumes (usually measured to a depth of 60 or 120 cm). This extra nitrate, detectable even during growth of the legume, results from a reduced use of soil nitrate ("nitrate-sparing", Evans et al, 1991;Herridge et al, 1994b;Herridge and Bergersen, 1988), the possible release of products of N2 fixation from nodulated roots (Ofosu et al, 1992(Ofosu et al, , 1993Pothet al, 1986;Sawatsky and Soper, 1991), or from N mineralized from fallen leaves or roots and nodules lost during growth and development. After a period of time the differences in levels of soil nitrate between legume and non-legume plots usually increase as N contained in the legume residues is released (Table 13).…”

“…Generally, nodulated legumes tend to release exudates more rich in LMW N than non-N-fixing plants (Rovira 1956;Paynel et al 2001;Phillips et al 2006;Lesuffleur et al 2007), which can be subsequently taken up by grasses. Legume species (Brophy et al 1987;Ofosu-Budu et al 1992) and cultivars (Thilakarathna et al 2013) can vary in their N exudation rate, making some individuals potentially better "N-donors" in the pathway. On the other side, it has been demonstrated that temperate perennial grasses can differ in their role as "N-receivers": species vary in their nitrogen use efficiency (NUE; Vazquez de Aldana and Berendse 1997) and their ability to take up specific forms of N (Wiegelt et al 2005).…”

ARTICLEInteractions between cultivars of legume species (Trifolium pratense L., Medicago sativa L.) and grasses (Phleum pratense L., Lolium perenne L.) under different nitrogen levels Abstract: The transfer of nitrogen (N) from legumes to grasses is an important process in low-input forage production systems, and may be improved by selecting compatible species and cultivars. This study sought to examine what effect species and cultivar have on plant growth and N accumulation in temperate grass-legume mixtures under a range of nitrogen fertility levels. A pot study using two cultivars each of alfalfa (Medicago sativa L.), red clover (Trifolium pratense L.), perennial ryegrass (Lolium perenne L.), and timothy (Phleum pratense L.) in all grasslegume combinations was devised. Compatibility indices, based on plant performance grown in combination versus alone, were used to quantify the net impact legumes and grasses had on each other. The presence of legumes had an overall negative effect on the growth of grasses (87% compared with growing alone), but did improve tissue N content by weight and total accumulated N. Improvements in total N were highest in a single timothy cultivar (Champ; 169%), but highest net total N was achieved in a ryegrass cultivar (Bastion; 1.92 mg N). Results indicate that grass N accumulation in legume-grass mixtures may be influenced more by grass N demand than legume supply, which suggests that competition between grasses and legumes may be a major determinant of N transfer efficiency.Résumé : Le transfert d'azote (N) des légumineuses aux graminées est un processus important dans les régimes de culture fourragère à faibles intrants et on pourrait l'intensifier en sélectionnant des espèces et des cultivars compatibles. Cette étude devait préciser dans quelle mesure l'espèce et le cultivar agissent sur la croissance de la plante et l'accumulation de N dans les mélanges combinant graminées et légumineuses pour climats tempérés, compte tenu d'un degré de fertilité variable pour l'azote. Les auteurs ont réalisé une expérience en pot sur deux cultivars, dans chaque cas, de luzerne (Medicago sativa L.), de trèfle rouge (Trifolium pratense L.), de raygrass vivace (Lolium perenne L.) et de fléole (Phleum pratense L.) en combinaisons graminées-légumineuses. Ils se sont servis d'indices de compatibilité s'appuyant sur la performance des plantes cultivées ensemble par rapport à leur performance lorsqu'elles sont cultivées seules, afin de quantifier l'impact net des légumineuses sur les graminées, et vice-versa. Les légumineuses ont un effet généralement négatif sur la croissance des graminées (87 % par rapport à la croissance observée sans compagnon), mais elles rehaussent la teneur en N dans les tissus selon le poids ainsi que la quantité totale de N accumulée. La hausse du N total la plus élevée a été observée chez un unique cultivar de fléole (Champ; 169 %), mais la plus forte hausse nette du N total a été obtenue avec un cultivar de raygrass (Bastion; 1,92 mg de N). Ces résultats indiquent que l'accu...
