Legume species

Fig. 6.3 Conceptual drawing of the distribution of different groups of herbaceous plants in relation to major plant nutrients. Cycles represent the distribution of grasses, herbs, and legumes. Species with mycorrhiza are able to exploit sites low in both nitrogen (N) and phosphorus (P). Highly productive species, such as ruderal plants, need conditions abundant in N and P.

Alkaloids take part in the life processes of some invertebrates as pheromones, inducers of sexual behaviour, and in reproduction. A case study of quinolizidine alkaloids and population changes proved that these alkaloids occur in all legume species studied but not, however, in all individuals. The distribution and frequency changes of alkaloidal and non-alkaloidal plants in populations is a direct expression of natural selection natural hybridization and micro-evolution can be considered as an evidence of current evolutionary responses by ecological and genetic systems.

Inoculation with specific strains of rhizobium bacteria stimulates nodulation on leguminous forbs, Commercial inoculants are available for the important legume species. Rhizobium bacteria may not survive or produce effective nodules in acidic spoils with pH below 5.0. 

Allen and Allen (1981) have described the little that is known about the introduction of legume species into agriculture and the role of inoculation in this process. For example, alfalfa (the hay of the Medes), Medicago sativa, was taken by the Spanish from the Middle east into South and Central America, from which point it spread to the north without, one presumes, deliberate use of soil inoculation. None of its cross inoculation group (species of Medicago, Melilotus or Trigonella) occur in the New World. Soyabean was introduced into America from Asia much later, and today both crops are routinely inoculated.

Legume species represent a wide variety of growth forms, ranging from annual plants to herbaceous perennials to woody shrubs, vines, and trees. 

The fruits of legumes are dry or fleshy, multi-seeded structures known as legumes or pods. The fruits and seeds of some legume species are highly nutritious because of their large concentrations of protein. The seeds of some species, however, contain toxic alkaloids and can be poisonous.
