BACKGROUND Molecular structures in feed protein influence its digestive behavior, availability and utilization. From a nutritive point of view, stage of maturity and cutting time are important factors affecting nutrient profiles and availability of alfalfa (Medicago sativa L.) hay in ruminants. The objectives of this study were to determine protein molecular structures by Fourier transform infr...

Fall dormancy (FD) in alfalfa (Medicago sativa L.) can be described using 11 FD ratings, is widely used as an important indicator of stress resistance, productive performance and spring growth. However, the contrasting growth strategies in internode length and internode number in alfalfa cultivars with different FD rating are poorly understood. Here, a growth chamber study was conducted to inve...

Arbuscular mycorrhizal fungi (AMF) are mutualistic symbionts associated with most terrestrial plants. HMA communities vary in composition and life histories affected by land use management. The caldén forests (Prosopis caldenia Burkart) the province of San Luis have suffered a considerable reduction their area. Currently, its relics part landscape made up lands cultivated Medicago sativa L. (al...

Intercropping of silage maize (Zea mays L.) and alfalfa (Medicago sativa is not a common practice because generally reduces grain biomass yield. The objective this research was to evaluate the productivity profitability maize–alfalfa intercropping, with goal establish increase in first year production. experiment conducted Fargo Prosper, ND, USA, 2014–2017. design randomized complete block four...

Abstract Alternative plant‐based protein sources are needed for supplementing or replacing fishmeal in formulated animal feeds. Alfalfa ( Medicago sativa L.), a perennial legume, is grown worldwide as high‐protein forage crop used primarily dairy and beef cattle However, its utility source feeding other farmed animals has great potential. Wet fractionation can provide several products that incr...

Aphids cause significant yield losses in agricultural crops worldwide. Medicago truncatula, a model legume, cultivated pasture species in Australia and close relative of alfalfa (Medicago sativa), was used to study the defence response against Therioaphis trifolii f. maculate [spotted alfalfa aphid (SAA)]. Aphid performance and plant damage were compared among three accessions. A20 is highly su...

When the temperature of incorporation of sodium acetate-1, 2-(14)C into lipids of alfalfa (Medicago media Pers. var. Rambler and Medicago sativa L. var. Caliverde) roots was lowered from 22 C to 1 C, elongation and desaturation of fatty acids and the labeling of phosphatidylcholine were strongly stimulated.Controlled hardening of alfalfa stimulated strongly the incorporation of sodium acetate-1...

allelopathy is one of the main factors limiting the plants growth. the present study investigated the effect of aqueous extract of leaves and fruit of artemisia sieberi that is an important species for rangeland rehabilitation on seed germination and seedling growth of three alfalfa species (medicago sativa cv. nikshahri, medicago polymorpha and medicago scutellata cv. robinson) in laboratory a...

In 1986, it was shown that tobacco plants and sunflower calluses could express recombinant human growth hormone as a fusion protein [1]. Since then, a diverse range of plant systems has been used for the production of pharmaceuticals [2, 3]. We have developed a production system based on the leaves of alfalfa (Medicago sativa L.), a choice made originally because of the plant’s many favorable a...
