Locust, black

Eor practical purposes, the sapwood of all species may be considered to be susceptible to biodeterioration. The heartwood of some species, however, contains toxic extractives that protect it against biological attack. Among the native species that have decay-resistant or highly decay-resistant heartwood are bald cypress, redwood, cedars, white oak, black locust, and black walnut (60). Douglas-fir, several of the pines, the larches, and honey locust...

More actinomycetous isolates were obtained from soils with a high organic matter content than from sandy soils with low organic matter (Table I). Sample I, collected under black locust trees, and sample P, collected under fescue sod in a young apple orchard, yielded the most isolates. Fewest isolates were obtained from sample A, which contained little organic matter due to having previously been burned, and samples C, H, and U, all sandy soils with low organic matter content. 

Source Indole was detected in jasmine flowers Jasminum officinale), licorice [Glycyrrhiza glabra), kohlrabi stems [Brassica oleraceavAT. gongylodes), and hyacinth flowers Hyacinthus orientalid at concentrations of 42 to 95, 2, 1.33, and 0.24 to 3.45 ppm, respectively. Indole also occurs in tea leaves, black locust flowers, corn leaves, petitgrain, and yellow elder (Duke, 1992).

Renewed interest in bark particleboard was evidenced by a short article written by Murphey and Rishel (39). They reported results of preliminary studies on relative strengths of various bark species compared to aspen flakeboard. Bark species included aspen, black locust, green oak, white pine, oak and locust, poplar, red oak, and mixed oak. Overlaying was suggested as a means of increasing bending strengths.

Although seeds are the common source of lectin activity, there are reports (some contradictory) of agglutinins occurring in leaves, stems, and roots.77,94 For example, black-locust (Robinia pseudoaccacia) lectin160 was isolated from its bark, potato (Solanum tuberosum) lectin161 from its tubers, and poke-weed (Phytolacca americanum) mitogen162 from its roots. A new class of plant cell-wall and membrane-bound lectins ( /3-lectins ) has been described.116,163,164 A treatise collected several schemes for the purification of lectins.165,1658... 

Cut ten twigs of four deciduous tree species, ranging from palatable such as aspen or willow, to least palatable such as red maple, black locust, or witch hazel. The actual species tested will vary from year to year, and with availability. Each twig is 60-cm long and has its leaves on. For one beaver site, collect ten such bows of each species. If you use more than one beaver site, you need multiple sets of ten twigs each.

Some North American examples cf tree-sized legumes that occur in temperate climates include the black locust Robinia pseudoacacia, yellow-wood Cladrastis luted, redbud Cercis canadefisis, haiey locust Gleditsia triacanthos, and Kentucky coffee tree GyninocloAus dioica. These are all native to parts of the eastern United States but are cultivated as ornamentals more widely, sometimes escapii into roadside and seccndaiy-forest habitats. 

Many tree-sized species in the legume family are valuable for their hard, durable timber. North American species are relatively minor in this respect, although the Kentucky coffee tree, black locust, and honey locust are used as lumber to some degree.

Plants that can cause CNS stimulation include larkspur, locoweed, lupine, water hemlock, and fi-tweed. Common plants that produce CNS depression are black locust, bracken fern, horsetail, milkweed. 

As Black Locust trees mature, the dark bark becomes marked with deep furrows and rounded ridges. The tree grows best in rich, moist soils of bottom lands and along streams, but also does well on waste land and on drier slopes. 

The hard, strong wood is very durable when in contact with the soil. It has been used extensively for mine props, railroad ties, and fence posts. This tree can also be found around older farms and houses and is also found along fence rows. Black locust bears abundant white flowers in late spring. Seeds ripen and are dispersed by gravity during the subsequent fall and winter.
