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 کاملPathways of Nitrogen Metabolism in Nodules of Alfalfa (Medicago sativa L.).
Exposure of intact alfalfa nodules to (15)N(2) showed that in bacteroids the greatest flow of (15)N was to NH(3). Label was also detected in glutamic acid, aspartic acid, and asparagine (Glu, Asp and Asn), but at far lower levels. In the host plant cytosols, more (15)N was incorporated into Asn than into other compounds. Detached nodules were also used to study the metabolic pathway of N assimi...
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 کاملAdenylate cyclase activity in a higher plant, alfalfa (Medicago sativa).
An adenylate cyclase activity in Medicago sativa L. (alfalfa) roots was partially characterized. The enzyme activity remains in the supernatant fluid after centrifugation at 105,000 g and shows in crude extracts an apparent Mr of about 84,000. The enzyme is active with Mg2+ and Ca2+ as bivalent cations, and is inhibited by EGTA and by chlorpromazine. Calmodulin from bovine brain or spinach leav...
