Cultivation of Alfalfa (medicago Sativa L)
Madicago sativa Linn, commonly known as 'Alfalfa', is a tonic plant rich in proteins, minerals, enzymes and vitamins, Bulk quantity of the whole plant is required in the pharmaceutical industries especially in homoecopathic pharmacies, Hence, there is a great need to cultivate this plant for sustained supply of the drug. Use of good and adequate phosphatecontaining farm yard manure, timely irri...
متن کاملAbstract Withholding alfalfa (Medicago sativa L.) irri-
Withholding alfalfa (Medicago sativa L.) irrigations during the summer, a practice referred to as summer irrigation termination (SIT), can conserve substantial amounts of water in long-season desert environments; however, plant mortality associated with SIT may be substantial. Proper timing of re-irrigation is critical for minimizing mortality and yield reductions following SIT. Procedures that...
متن کاملDetection of Norspermidine and Norspermine in Medicago sativa L. (Alfalfa).
Shoot meristem tissues of alfalfa, Medicago sativa L., were found by high performance liquid chromatography analyses to contain the uncommon polyamines, norspermidine and norspermine. The chemical structures of norspermidine and norspermine, purified from alfalfa, were confirmed by comparison of mass spectra with those from authentic standards. The discovery of norspermidine and norspermine in ...
متن کاملThe Effects of Heavy Metals and Root Immersion on Isoflavonoid Metabolism in Alfalfa (Medicago sativa L.).
Modest increases in the concentration of medicarpin, 6-fold in leaves and 4-fold in roots, were observed in alfalfa (Medicago sativa L.) seedlings treated with 1 mM metal salts for 72 h. However, medicarpin-3-O-glucoside-6"-O-malonate (MGM) and formononetin-7-O-glucoside-6"-O-malonate (FGM) levels were up to 50-fold lower in metal-treated compared to control roots. Approximately 10% of the "mis...
متن کاملAlfalfa (Medicago sativa L.) Root Exudates Contain Isoflavonoids in the Presence of Rhizobium meliloti.
Root exudates of alfalfa (Medicago sativa L.) inoculated with symbiotic Rhizobium meliloti bacteria contained three isoflavonoids that were not found in exudates of uninoculated plants. Data from proton nuclear magnetic resonance, mass spectrometry, and ultraviolet-visible absorbance analyses indicated that root exudates of inoculated plants contained aglycone and glycoside forms of the phytoal...
