Warming Reduces Net Carbon Gain and Productivity in Medicago sativa L. and Festuca arundinacea

Ergovaline levels in cultivars of Festuca arundinacea

Abstract 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...

Detection 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 ...

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...

Role of Potassium in Carbon Dioxide Assimilation in Medicago sativa L.

Alfalfa was grown hydroponically in 0, 0.6, and 4.8 millimolar K in order to determine the influence of tissue level of K on photosynthesis, dark respiration, photorespiration, stomatal and mesophyll resistance to CO(2), photosystem I and II activity, and synthesis and activity of ribulose 1,5-bisphosphate carboxylase (RuBPc).A severe (0.0 millimolar) and mild (0.6 millimolar) K deficiency, com...
