leucocephala can be restrained. Among 700 international collections of this self-fertile species grown in Hawaii, most were identical seedy shrubs, the ‘common type’ widely used for … In general, the primary roots tend to be positively geotropic, secondary It is a fast growing plant with an extensive root system and has been used in land reclamation, for preventing soil erosion and as a shade plant for coffee crops[200. leucocephala, was deliberately imported last century as fodder, fuel wood, shade, food and green manure, but is now a visible ruderal weedy shrub, mostly of roadsides, disturbed sites and creeks. Leucaena leucocephala ssp. Varieties of the second subspecies, Leucaena leucocephala ssp. This is also so with gliricidia especially in Tobago. 20) m with a bole diameter of 10–50 cm and a bole hight to 5 m. L. leucocephala has an upright angular branching, which forms a narrow open crown. Root branch angles are the key components of root system architecture; lateral roots diverge from parent roots at wider angle, which influence chances of their entry to unexploited horizons (Fitter, 1991). (79.00C) minimum in case of Leucaena leucocephala (47.20C). de Wit) is a fast growing, evergreen, thornless shrub, reaching a height of 5 m (Hawaiian type) to 20 m (Hawaiian giant type) ().Leucaena is a long-lived perennial legume (around 23 year half-life in difficult conditions in Australia). Leucaena is a fast growing, evergreen, thornless shrub that grows up to 20 m tall (FAO 2009). III. Leucaena leucocephala is the familiar leucaena throughout the lowland tropics on less acid soils, known by a hundred vernacular names. Leucaena leucocephala is an aggressive colonizer of disturbed ground and ruderal sites, and thus an excellent pioneer species for restoring woodland cover[1518. Total carbohydrate (18.6%), reducing sugars (4.2%), oligosaccharide sucrose Shallow root systems may be desirable if the trees are intended to stabilize soil and the question of competition with crops is less important. Leucaena (Leucaena leucocephala (Lam.) Reduction in tree sizes of L. leucocephala in the mixed planting stands might be determined by the structure and interactions of the root systems. The root system is the most important organ of plant nutrition. Leucaena leucocephala, also known as Leucaena glauca is a highly branched small tree or shrub, which belongs to the family Mimosaceae.Leucaena is an evergreen, deep rooted plant, which may grow to heights of 3–15 (max. available to the root system, Leucaena forage can be an excellent source of calcium, phosphorus, and other dietary minerals [29, 32, 33, 39, 42, 55] but is deficient in sodium [29, 32, 42, 55]. Leucaena is known to be intolerant to soils with low pH (below pH 5.5), low potassium, low calcium, high salinity, high aluminium and waterlogging [3]. It … glabrata, were developed in Queensland to be used in a Single-node leafy and leafless cuttings harvested from one-year-old, 1.3 to 1.5 m tall Leucaena leucocephala seedlings were successfully rooted in a non-mist propagator which is suitable for use in the rural tropics. This perennial legume is well adapted to our local conditions and can be seen growing wild along the roadways. RESULTS AND DISCUSSION A. Botanical CharactersLeucaena leucocephala is a perennial, non-limbing, erect, thornless shrub or small tree, 5-10 m (rarely 20 m) tall. Very limited data are available on the carbohycrates present in the leaves. Cuttings with a leaf attached rooted more successfully than those without a leaf (71% and 39% respectively) and clones differed significantly (43% to 71%).
