Leucaena leucocephala x Leucaena diversifolia Hybrid andIts Parental Genotypes P. SOMASEGARAN*ANDR. The wood can be used for fire and charcoal and the plant is eaten by cattle and goats, but can be toxic at high levels, especially for horses. Leucaena leucocephala, as a shrub legume rich in condensed tannins, is a candidate for the integrated control of gastrointestinal parasitic pathogen nematodes. The leaves (up to 35 cm long) are twice-compound (bipinnate) and have 3-10 pairs of branchlets (pinnae). It is especially abundant in the humid coastal lowlands and in other humid areas. Triclopyr ester applied basal bark and stump bark is effective, while 2,4-D in combination with diesel fuel is effective for basal bark treatments. The morphological characteristics of the fruits and seeds, germination and seedling growth performance of Ipil-Ipil (Leucaena leucocephala (Lam.) Ranging from Warm Temperate Dry to Moist through Tropical Very Dry to Wet Forest Life Zone, leadtree is reported to tolerate annual precipitation of 1.8 to 41.0 dm (mean of 30 cases = 14.9), annual mean temperature of 14.7 to 27.4°C (mean of 30 cases = … Leucaena leucocephala is a shrub or small tree usually growing 2-10 m tall, but occasionally reaching 15 m or more in height. It forms a small to medium-sized thornless tree 3-15 (-20)m tall and 5-50cm bole diameter. Introduced to Hawaii after 1864. Lead tree may have been introduced into Florida for cattle fodder and controlling erosion. The light pods may also be spread short distances by wind and can float on water. Leucaena leucocephala is one of the fastest-growing leguminous trees. Leucaena leucocephala is a small, variably shrubby and highly branched (ssp. These pods (8-22.5 cm long and 10-20 mm wide) are initially green in colour, but turn brown or reddish-brown as they mature. 2014). The dark brown seed pods are flat, roughly 4 to 6 inches long, with about 20 seeds. Seeds are glossy brown, oval, flat, 6 mm long. 20) m tall, bole diameter 10-50 cm. This amino acid is responsible for the poor growth performance of cattle when this plant provides more than one-half of the diet. It was introduced into Taiwan, probably by the Portuguese or the Dutch, in … Usage of trees with fast-growing characteristics is essential to add feedstock sources to mills. Leucaena leucocephala grows very fast in suitable sites; pollarding and coppicing to form dense, homogenous thickets that are difficult to control once established. Lead tree is sensitive to foliar-applied triclopyr. commercial use or for woodlots, animal fodder, soil stabilisation, etc. Once L. leucocephala establishes itself it displaces native vegetation and can promote suitable conditions for the establishment of even more aggressive invaders. young flower clusters in bud (Photo: Sheldon Navie), twice-compound leaves and flower clusters (Photo: Sheldon Navie), close-up of leaf showing raised gland and elongated leaflets (Photo: Sheldon Navie), old flower cluster with young fruit beginning to develop (Photo: Sheldon Navie), close-up of flower cluster and leaf stalk with raised gland (Photo: Sheldon Navie), close-up of seeds (Photo: Steve Hurst at USDA PLANTS Database), Leucaena, south of Kasese, Uganda (Photo: Geoffrey Howard, IUCN).

Each of these pods contains 10-25 hard seeds (6-10 mm long and 3-6 mm wide) that are glossy brown, flattened (compressed), and somewhat oval (elliptic-oblong) in shape. Lead tree was most likely distributed by man because of its many uses. In Uganda, it was introduced in tea plantations and as a host for the vanilla orchid (Vanilla planifolia) and later planted among other crops as a nitrogen fixer. de wit.) The fruit are elongated (linear), flattened, pods with a pointed tip (beaked apex). Koa haole, leucaena Leucaena leucocephala (Lam.) The first step in preventative control of lead tree is to limit planting and removal of existing plants within the landscape. Locations within which Leucaena leucocephala is naturalised include parts of South America (outside its native range), Asia, southern USA, southern Europe, Australia, Africa and many oceanic islands with warm climates. In areas where lead tree is considered an invasive weed, it will forms dense thickets and displaces the native vegetation. Older stems have a relatively smooth, greyish or greyish-brown, bark with numerous small raised spots (lenticels).

Each of the small flowers has five tiny sepals (2-2.5 mm long), five small greenish-white coloured petals (2-4 mm long), and ten prominent pale yellow or whitish coloured stamens (6-10 mm long). There are two sub-species of Leucaena leucocephala: L. leucocephala subsp. A very troublesome weed of riparian zones (banks of watercourses) and roadsides in tropical and subtropical regions. The flowers are borne in dense globular clusters (12-30 mm across), which look like a 'pompom' when the flowers open. These plants are allowed in certain areas under controlled conditions). KUMASI, GHANA ABSTRACT Growth, wood yield, specific gravity, calorific value and chemical composition (ie. Found in Southern Florida, including the Florida Keys, lead tree can be seen along roadsides and hammock margins in Miami-Dade and Monroe counties. When using any herbicide always read the label first and follow all instructions and safety requirements. Some components of an integrated management approach are introduced below. It comprises 3–5% of the dry weight of the protein. The fast-growing plant exhibits an open, spreading habit with a trunk diameter between 4 and 10 inches. Grazing by goats has been used as an effective control method in controlled situations. Seeds are glossy brown, oval, flat, 6 mm long. GISD (2010). Goats will provide a large level of control if allowed to continuously graze. Invaded areas become unusable and inaccessible with most other vegetation replaced. L. leucocephala constitutes a threat to native biodiversity. Cutting and uprooting can work for younger plants at a localised scale but older plants are likely to resprout after such interventions. Continuous cutting will eventually kill larger trees. www.ars-grin.gov/npgs/index.html. Individual flowers are white, turning brown with maturity. Controlling the weed before it seeds will reduce future problems. The genus Leucaena is distinguished from all other Mimosoid legumes by its hairy anthers which are easily visible with a hand lens.Leucaena leucocephala is distinguished from other species of Leucaena by its intermediate leaflets and large pods in clusters of 5-20 per flower head.

If in doubt consult an expert. de Wit. Leucaena leucocephala is invasive in parts of Kenya, Tanzania and Uganda (Lyons and Miller 1999). The precise management measures adopted for any plant invasion will depend upon factors such as the terrain, the cost and availability of labour, the severity of the infestation and the presence of other invasive species. Leucaena (Leucaena leucocephala (Lam.) Leucaena leucocephala (local name ipil-ipil) is one of the most productive fast-growing, semi-evergreen and nitrogen-fixing tropical legume tree.

Acacia leucocephala (Lam.) L. leucocephala has a number of biological characteristics which are regarded as indicating invasive tendancy and make it difficult to control, e.g. It is highly tolerant to drought mainly because of its extensive root system. Nairobi, Kenya. These two sub-species can be distinguished by the following differences: Other Leucaena species have been introduced to East Africa such as L. diversifolia, L. pallida and L. trichandra. Probably introduced into the Philippines in the 16th Century as a feed for in the rest of the country. Older stems have a relatively smooth, greyish or greyish-brown, bark with numerous small raised spots (lenticels).
