| [vegetation biomass allocation and its spatial distribution after 20 years ecological restoration in a dry-hot valley in yuanmou, yunnan province of southwest china]. | by using layering harvest method, a comparative study was conducted on the biomass allocation and its spatial distribution of 20-year-old eucalyptus camaldulensis plantation, leucaena leucocephala plantation, and e. camaldulensis-l. leucocephala plantation in yuanmou dry-hot valley of yunnan province, southwest china. the stand biomass in the mixed e. camaldulensis-l. leucocephala plantation (82.99 t x hm(-2)) was between that of monoculture e. camaldulensis plantation (60.64 t x hm(-2)) and l. ... | 2013 | 24066529 |
| potential of different am fungi (native from as-contaminated and uncontaminated soils) for supporting leucaena leucocephala growth in as-contaminated soil. | arbuscular mycorrhizal (am) fungi inoculation is considered a potential biotechnological tool for an eco-friendly remediation of hazardous contaminants. however, the mechanisms explaining how am fungi attenuate the phytotoxicity of metal(oid)s, in particular arsenic (as), are still not fully understood. the influence of as on plant growth and the antioxidant system was studied in leucaena leucocephala plants inoculated with different isolates of am fungi and exposed to increasing concentrations ... | 2017 | 28214191 |
| native rhizobia from zn mining soil promote the growth of leucaena leucocephala on contaminated soil. | plants on contaminated mining soils often show a reduced growth due to nutrient depletion as well as trace elements (tes) toxicity. since those conditions threat plant's survival, plant growth-promoting rhizobacteria (pgprs), such as rhizobia, might be of crucial importance for plant colonization on te-contaminated soils. native rhizobia from mining soils are promising candidates for bioaugmented phytoremediation of those soils as they are adapted to the specific conditions. in this work, rhizob ... | 2017 | 27409290 |
| comparison of the effects of mesquite pod and leucaena extracts with phytoestrogens on the reproductive physiology and sexual behavior in the male rat. | mesquite (prosopis sp.) and leucaena leucocephala are widespread legumes, widely used to feed several livestock species and as food source for human populations in several countries. both mesquite and leucaena contain several phytoestrogens which might have potential estrogenic effects. thus, the aim of this study was to evaluate the effects of mesquite pod and leucaena extracts on several aspects of behavior and reproductive physiology of the male rat. the effects of the extracts were compared ... | 2016 | 27163522 |
| leucaena sp. recombinant cinnamyl alcohol dehydrogenase: purification and physicochemical characterization. | cinnamyl alcohol dehydrogenase is a broad substrate specificity enzyme catalyzing the final step in monolignol biosynthesis, leading to lignin formation in plants. here, we report characterization of a recombinant cad homologue (llcad2) isolated from leucaena leucocephala. llcad2 is 80 kda homo-dimer associated with non-covalent interactions, having substrate preference toward sinapaldehyde with kcat/km of 11.6×10(6) (m(-1) s(-1)), and a possible involvement of histidine at the active site. the ... | 2014 | 24064207 |
| cyclic-β-glucans of rhizobium (sinorhizobium) sp. strain ngr234 are required for hypo-osmotic adaptation, motility, and efficient symbiosis with host plants. | cyclic-β-glucans (cβg) consist of cyclic homo-polymers of glucose that are present in the periplasmic space of many gram-negative bacteria. a number of studies have demonstrated their importance for bacterial infection of plant and animal cells. in this study, a mutant of rhizobium (sinorhizobium) sp. strain ngr234 (ngr234) was generated in the cyclic glucan synthase (ndvb)-encoding gene. the great majority of cβg produced by wild-type ngr234 are negatively charged and substituted. the ndvb muta ... | 2012 | 22583376 |
| mimosine content of leucaena leucocephala and the sensitivity of rhizobium to mimosine. | mimosine was qualitatively and quantitatively estimated from the different parts of leucaena leucocephala strains k-8 and k-67. the amount of mimosine as percentage of dry weight in the two strains were, respectively, as follows: seeds, 6.82, 9.98; old leaves, 1.5, 1.33; young leaves, 2.85, 3.33; main root, 1.13, 1.02; lateral roots, 1.46, 1.17; stems, 0.73, 0.33. rhizobium isolates from l. leucocephala (uas-ll-8, uas-ll-67), mimosa pudica (uas-mp) and prosopis juliflora (uas-pj) formed an effec ... | 1985 | 23195805 |
| buffer nitrogen solubility, in vitro ruminal partitioning of nitrogen and in vitro ruminal biological activity of tannins in leaves of four fodder tree species. | this study explores the chemical composition, buffer n solubility, in vitro ruminal n degradability and in vitro ruminal biological activity of tannins in leaves from gliricidia sepium, leucaena leucocephala, morus alba and trichanthera gigantea trees. these tree leaves are a potential protein source for ruminants, but their site-influenced nutritive value is largely unknown. leucaena leucocephala leaves had the highest n content (42.1 g/kg dm), while t. gigantea leaves had the least (26.1 g/kg ... | 2014 | 24750263 |
| feeding potential of cassava (manihot esculenta crantz) peels ensiled with leucaena leucocephala and gliricidia sepium assessed with west african dwarf goats. | cassava peels (cape) were ensiled in mixtures with gliricidia sepium and leucaena leucocephala, and the utilization of the mixed silages by west african dwarf (wad) goats was assessed. five silages were composed, comprising of 100% ensiled cape (control), cape + g. sepium 2:1 (w/w; 2cgs), cape + g. sepium 1:1 (w/w; cgs), cape + l. leucocephala 2:1 (w/w; 2cll) and cape + l. leucocephala 1:1 (w/w; cll). all diets were supplemented with molasses (40 g/kg) before ensiling which lasted 3 months. fift ... | 2013 | 23397521 |
