Spanish broom spartium junceum9/13/2023 ![]() The species is hermaphrodite (has both male and female organs) and is pollinated by Insects. ![]() ![]() It is in flower from June to September, and the seeds ripen from August to October. These were 20 more evident for the samples composed of pieces with larger diameter, and may be attributed to the loose nature of the tested samples. Spartium junceum is a deciduous Shrub growing to 3.5 m (11ft) by 3 m (9ft) at a fast rate. The main limit of the investigated samples was the appearance of sound absorption resonances. The increase in the sample thickness allowed to obtain higher sound absorption at lower frequencies, as generally expected for porous materials. Results are particularly 15 promising especially above 500 Hz, as the samples consistently reported a normal sound absorption above 0.5. The normal sound absorption for samples with a thickness of 60 mm, 80 mm and 120 mm was then measured. Test specimens made of broom pieces with a diameter from 1.5 mm to 4 mm were prepared. The materials were cut and shredded to prepare several samples. Flowers: Are yellow, pea-like and fragrant.They occur at the end of the stem and are up to 3 cm long. Broom plants grow up on 10 hills and mountains and are common in many Mediterranean countries. General: Spanish Broom is a perennial, deciduous shrub that may live up to 30 years. ![]() If an internal link led you here, you may wish to change the link to point directly to the intended article. Spartium junceum (Spanish broom) is a deciduous shrub (family Fabaceae) found throughout the western part of California. Spanish broom (Spartium junceum L.), a member of the Leguminosae family, has been considered a potential interesting source of natural, sustainable, and renewable fiber for textile and technical. Large (an inch or more), light yellow, pea-like flowers appear on outer canopy branches in late spring. Leaves are present on the plant from February to early June and are about half an inch long. This disambiguation page lists articles associated with the title Spanish broom. Description Spanish broom grows more than head high, with cylindrical rush-like branches that are green when young and turn brown as branches mature. In this paper, the acoustic properties of broom fibers are reported and discussed. Spanish broom may refer to: Genista hispanica, a low-growing spiny shrub. It is effective in slope stabilization, but less suitable for soil bio-engineering or for triggering natural plant succession.Natural materials are becoming a valid alternative to traditional synthetic ones for sound absorption applications. Our results show that Spanish Broom has good bio-mechanical characteristics with regard to slope stabilization, even in critical pedoclimatic conditions and where inclinations are quite steep, and it is effective on soil depths up to about 50 cm, in agreement with other studies on Mediterranean species. These tests confirmed that agamic propagation is difficult, even though roots were produced from some buried stems, and for practical purposes it has been ruled out. The measurement and calculation of mean root number, mean root diameter, RAR, root cohesion and Factor of safety are presented in order to distinguish the effect of plant origin and propagation.įurthermore, tests were performed to assess the possibility of agamic propagation (survival rate of root-ball endowed plants, rooting from stem cuttings). ![]() The data obtained were used to analyze the stability of an artificial slope (landfill) and the root reinforcement. The four most common broom species in California are Scotch broom (Cytisus scoparius), French broom (Genista monspessulana), Spanish broom (Spartium junceum), and Portuguese broom (Cytisus striatus). The Root Area Ratio (RAR) was analyzed by taking both direct and indirect measurements, the latter relying on image processing. Analysis were performed on the root systems in order to assess root density distribution. Single root specimens were sampled and tested for tensile strength, obtaining classic tensile strength-diameter relationships. In particular, the aims of the study were 1) to investigate the plant's bio-mechanical aspects and 2) to verify whether root reinforcement and the field rooting ability of stem cuttings enhance its potential for use in slope stabilization and soil bio-engineering techniques, particularly in the Mediterranean areas. The present paper deals with the root system's characteristics of Spanish Broom ( Spartium junceum L.), a species whose capacity for adaptating and resisting to drought is worth investigating. ![]()
