| ecological distribution of spirillum lipoferum beijerinck. | a survey in various countries revealed that the n2-fixing spirillum lipoferum beijerinck is a very common root and soil inhabitant in the tropics. more than half of the grass root and soil samples collected in tropical countries (four african countries and brazil) contained abundant s. lipoferum populations, while less than 10% of the samples collected in temperate south brazil, kenya, and the u.s.a. contained the organism. there is a pronounced vegetation effect. panicum maximum seems the most ... | 1976 | 10062 |

| serotyping and strain identification of maize streak virus isolates. | four strains of maize streak virus, namely the panicum maximum, digitaria setigera and sugarcane strains, have been identified from 19 isolates by elisa using polyclonal antisera cross-absorbed with particles of the maize strain. the results suggest there is an epitope of the maize strain which is not dependent on the capsid being intact and which is common to all the members of the group; other strain-specific epitopes are probably conformation-dependent. a specific epitope (probably internal) ... | 1990 | 1697327 |
| measurement and kinetic analysis of the neutral detergent-soluble carbohydrate fraction of legumes and grasses. | the fermentation of the neutral detergent-soluble (nds) fraction of two legumes (clover, alfalfa) and two grasses (timothy, guinea grass) was measured using a curve subtraction technique with in vitro gas production data from the whole forage and the isolated neutral detergent-extracted fiber. the ndf disappearance and vfa production also were measured. there were no significant differences between the vfa patterns from whole forage and ndf. there was a good linear correlation between the volume ... | 1995 | 8586606 |
| urea ammoniation effects on the feeding value of guineagrass (panicum maximum) hay. | laboratory, digestion, and growth studies evaluated urea as a source of ammoniation for quality improvement in guineagrass (panicum maximum) hay. in a laboratory trial, 5.0-kg portions of hay were reconstituted with water to yield final forage moisture concentrations or 25 of 40% and treated with urea at 0, 4, 6, or 8% of the forage dm, with or without urease addition. main effects of forage moisture or urease addition did not influence (p > .10) cp or ndf concentration or in vitro om disappeara ... | 1995 | 8617681 |
| identification and characterization of enterococcus species isolated from forage crops and their influence on silage fermentation. | forty-eight strains of lactic acid bacteria were isolated from forage crops, and their identification, characterization and influence on silage fermentation were studied. all isolates were gram-positive, short-chain-forming, catalase-negative, and facultatively anaerobic cocci that did not produce gas from glucose, only formed l-lactic acid, and were able to grow at ph 9.6%, in 6.5% nacl, or with 40% bile, but not below ph 4.5. these isolates were commonly isolated from forage crops, and they we ... | 1999 | 10575614 |
| feasibility of using lignin isolated from forages by solubilization in acetyl bromide as a standard for lignin analyses. | lignin concentration can be measured in plants by the acetyl bromide-soluble lignin spectrophotometric method; however, as with any spectrophotometric method, a reliable standard is needed. in the present experiments, lignin was extracted from each of the forages under study with the acetyl bromide reagent. the lignin isolated with acetyl bromide (liab) was then used as the reference standard in the acetyl bromide-soluble lignin (absl) analysis, which was compared with the acid detergent lignin ... | 2000 | 11132828 |
| estimation of bundle sheath cell conductance in c4 species and o2 insensitivity of photosynthesis. | low conductance to co2 of bundle sheath cells is required in c4 photosynthesis to maintain high [co2] at the site of ribulose-1,5-bisphosphate carboxylase/oxygenase (rubisco). elevated [co2] allows high co2 assimilation rates by this enzyme and prevents rubisco oxygenase activity and o2 inhibition of carboxylation. bundle sheath conductance to co2 was estimated by chemically inhibiting phosphoenolpyruvate carboxylase and calculating the slope of the linear response of leaf co2 uptake to [co2]. t ... | 1993 | 12232010 |
| regulation and roles of phosphoenolpyruvate carboxykinase in plants. | phosphoenolpyruvate carboxykinase (pck) is probably ubiquitous in flowering plants, but is confined to certain cells or tissues. it is regulated by phosphorylation, which renders it less active by altering both its substrate affinities and its sensitivity to regulation by adenylates. in the leaves of some c4 plants, such as panicum maximum, dephosphorylation increases its activity in the light. in other tissues such regulation probably avoids futile cycling between phosphoenolpyruvate and oxaloa ... | 2003 | 12781772 |
