Mediterranean forage legumes grown alone or in mixture with annual ryegrass: biomass production, N2 fixation, and indices of intercrop efficiency
2016
Aims: To evaluate the productivity and N2 fixation of a range of Mediterranean forage legume species as well as their ability to be grown in mixture with a forage grass, and to verify whether N transfer occurs from the legume to the non-legume component of the mixtures and, if so, to what extent this process is affected by legume species. Methods: Seven legume species (Hedysarum coronarium L., Medicago scutellata L., Trifolium resupinatum L., Trifolium squarrosum L., Trigonella foenum-graecum L., Vicia sativa L., Vicia villosa Roth) were grown alone or in mixture with annual ryegrass (Lolium multiflorum L.). Biomass and N yields and biological N2 fixation (15N dilution technique) were measu…
Vicia brulloi (Fabaceae), a new species from Sicily
2019
Vicia brulloi, a new species from Peloritani range in NE Sicily, is described and illustrated. It is a perennial climbing liane linked to riparian woods, showing close relationship mainly with V. pisiformis, having a scattered European distribution. In particular, V. brulloi is a very rare and extremely localized species morphologically well distinct from V. pisiformis in several remarkable features, such as the dense indumentum covering the vegetative structures and calyces, the shape and size of flower pieces, pods, seeds, as well as seed testa micromorphology. Another relevant peculiarity of V. brulloi is the lower tooth of the calyx replaced by a green leafy appendix, character infreque…
