The rumen bacterial strains Butyrivibrio fibrisolvens Hl7c, Fibrobacter succinogenes S8S, Lachnospira multiparus 4°, Ruminococcus albus 7 and R. flavefaciens FD-l were compared individually and as a five-species mixture with a rumen inoculum for their ability to degrade lucerne (Medicago sativa L.) stem cell wall polysaccharides. Two maturity stages oflucerne (bud and full flower) were utilized...

Plant nutrients might affect the activity and bioavailability of heavy metals in the soil –plant environment thus their accumulation in the plant. Little is known about the effect of nitrogen fertilization on cadmium (Cd) uptake by alfalfa “Medicago sativa”. This work aims to characterize the oxidative status, the physiological stress parameters and the Cd uptake in alfalfa « Medicago sativa » ...

The aim of this study was to determine the nutritive value of some legume species in salt-affected soils of South-East Anatolian region using chemical composition and in vitro gas production kinetics. In this study, Lotus corniculatus, Trifolium alexandrinum, Medicago sativa were sown and tested in four different locations. A 3 by 4 factorial design with 3 legume species and 4 salt levels (non ...

in order to assess the effect of salinity constraint on some agro-physiological and biochemical traits in medicago sativa l., four alfalfa populations (tafilalet 1, tafilalet 2, demnate and tata), originated from mountains and oasis of morocco, were tested. the plants were grown under greenhouse conditions in pots filled with sand and peat under three salt treatments (0, 100 and 200 mm nacl). t...

Long-term persistence and sustained biomass yields of alfalfa (Medicago sativa L.) stands are important to producers. Yield performance and persistence of intrasubspecific crosses between alfalfa subspecies sativa and falcata after the first post-establishment year are unknown. The objectives of this study were to measure biomass yields, persistence, and biomass yield stability in interand intr...

Insect populations feeding on different plant species are under selection pressure to adapt to these differences. A study integrating elements of the ecology, behavior, and gene expression of aphids on different host plants has not yet been well-explored. The present study explores the relationship between host fitness and survival, feeding behavior, and salivary gland gene expression of a pea ...

A pot experiment was performed to study the effectiveness of remediation using different plant species and the enzyme response involved in remediating PAH-contaminated soil. The study indicated that species Echinacea purpurea, Festuca arundinacea Schred, Fire Phoenix (a combined F. arundinacea), and Medicago sativa L. possess the potential for remediation in PAH-contaminated soils. The study al...

Abiotic constraints are a source of concern in agriculture, because they can have a strong impact on plant growth and development, thereby affecting crop yield. The response of plants to abiotic constraints varies depending on the type of stress, on the species and on the organs. Although many studies have addressed different aspects of the plant response to abiotic stresses, only a handful has...

Salinity, alkalinity and drought stress are the major abiotic stresses hindering the productivity of alfalfa (Medicago Sativa) in arid and semi-arid regions. Therefore an ecological survey was conducted to characterize 600 Sinirhizobium strains of diverse geographical origin, isolated from the root nodules of alfalfa (Medicago Sativa). Rhizobial isolates were studied under free living condition...
