New knowledge in findings potential usage of natural fiber as new material in composite technology has been increased gradually in years and these natural fiber materials are well known as competent material which can become an alternative material to the conventional and synthetic materials for suitable applications. In this research, Casuarina equisetifolia leaf was used as bio-based fiber and unsaturated polyester composite as the matrix due to its natural surface roughness without any chemical treatment. The aim of this study was to investigate the effect of various weight loadings of Casuarina equisetifolia in unsaturated polyester composites on the tensile test and morphological studies. The composite samples were fabricated by using press machine with mould dimension of (15x15x0.3) cm. From the tensile test results, tensile strength of the composite samples decreases with the increment of Casuarina equisetifolia by weight loadings. The surface morphology of the fractures composite samples was then analyzed using the microscopy technique (SEM) and found the evidence of fractured fiber breakage and voids content of the samples. Base on the result obtained, the tensile strength at 30% up to 50% weight loading of Casuarina equisetifolia has the potential to be used in non-structural applications.

Background: Enterococcus faecalis is one of the bacteria that can form biofilms that can cause persistent endodontic infections. Biofilm is the unity of microbial cell surface surrounded by a matrix of extracellular polymeric substances (EPS). The ethanol extracts of Casuarina equisetifolia leaves are known to have potentially bioactive compounds as antibacterials such as flavonoids, saponins, tannins, phenols, and alkaloids.

Antecedentes: los estudios de polinosis efectuados en la Ciudad de México han encontrado una cantidad importante de polen de Casuarina equisetifolia y Pinus spp, la frecuencia de sensibilización a estos pólenes se desconoce. Estos alergenos no se han relacionado con asma bronquial o rinitis alérgica en México, a pesar de que estudios efectuados en otros países han demostrado su relevancia como aeroalergenos.Objetivo: determinar la frecuencia de sensibilización al polen de Casuarina equisetifolia y Pinus spp.Pacientes y método: estudio transversal, descriptivo, efectuado en el servicio de Alergia e Inmunología Clínica del Hospital General de México. Previo consentimiento informado, se incluyeron 142 pacientes de 3 a 55 años de edad con diagnóstico de rinitis alérgica, asma o ambas. Se les realizó historia clínica completa, estudios de laboratorio, gabinete y pruebas cutáneas por punción.Resultados: de los 142 pacientes, se incluyeron 44 niños (64% de sexo masculino) y 98 adultos (73% de sexo femenino). Se encontró que 8 (18.1%) niños y 35 (35.7%) adultos tuvieron reacción positiva en la prueba cutánea para Casuarina equisetifolia. Ninguno de los pacientes incluidos en el estudio tuvo reacción positiva a la prueba cutánea para Pinus spp. La frecuencia de sensibilización a Casuarina equisetifolia fue ligeramente menor a la de otros pólenes frecuentemente encontrados en la Ciudad de México.Conclusiones: la sensibilización al polen de Casuarina equisetifolia es tan importante como la de otros pólenes encontrados en la Ciudad de México. Con estos resultados se sugiere que este polen se incluya en la práctica de pruebas cutáneas. El polen de Pinus spp es un aeroalergeno en países europeos. Sin embargo, en nuestra población no corroboramos la sensibilización al mismo.

The present report gives an account of the results of research carried out on litter production, accumulation and nutrient return through rainfall, stem flow, throughfall and interception to soil litter fall, under Casuarina-Black Gram Agroforestry Models (age 4 years, density 650 trees/ha). It was found that of the total rainfall (497.9 mm) 1.2% was recorded as stem flow and 80% as throughfall while the interception accounted for 19 %. It is found that on an average annual basis, of the total uptake of various nutrients was retained in the non-photosynthetic biomass and the rest returned to soil. These results show that among the nutrients, maximum annual retention was accounted for potassium while, the minimum for nitrogen. This paper deals the nutrient accumulation in standing crop, nutrient concentration and return, rainfall interception, nutrient concentration in rain wash, nutrient return through rain wash and Nutrient retained, returned and uptake (kg/ha/yr) in Casuarina under Agroforestry System in detail.

Seeds collected from 28 natural provenances and introduced populations of Casuarina equisetifolia subsp. equisetifolia L. from Oceania, Asia and Africa were used to study geographic variation in growth and morphology of nursery-grown seedlings. Ten characteristics related to growth and branching habit were measured for each seedling and the resultant data subjected to univariate and multivariate analyses. In general, seedlings from Oceania grew more slowly, were more densely branched with fine and upright branching, and had fewer teeth per whorl than those from other areas. Cluster analysis effectively separated Oceania from Asian natural provenances, and revealed the probable original sources of introductions to different parts of Asia and Africa. Further investigation into the pattern of variation through molecular characterisation of genetic material from all major regions of distribution is warranted in order to better understand the genetic relationships and enhance more efficient utilisation of this important casuarina species.

Objectif : L’objectif est de contribuer à enrichir la gamme d’espèces végétales utilisables dans la restauration et la valorisation des terres salées. Méthodologie et résultats : Dans 3 essais indépendants et selon un dispositif complètement aléatoire, des plants de Casuarina equisetifolia, Gossypium hirsutum et Jatropha curcas ont été arrosés avec une solution de NaCl de concentrations variant de 0 à 23,36 g.l-1 et suivis pendant deux mois. Ensuite, ils ont été soumis à un test de toxicité de concentrations 8 fois plus élevées. Les résultats montrent que les concentrations utilisées au début sont moins néfastes pour la croissance et la production de biomasse chez G. hirsutum et C. equisetifolia que chez J. curcas. Elles augmentent la production de litière chez J. curcas. Conclusion et application des résultats : Les résultats obtenus peuvent expliquer qu’entre 46,72 et 186,88 g.l-1, la solution de NaCl fut létale (44 à 100% de mortalité) pour C. equisetifolia et G. hirsutum mais pas pour J. curcas qui n’a enregistré aucune mortalité. Ainsi, jusqu’à une concentration de 23,36 g.l-1, les trois espèces réagissent différemment. De ce fait, il en ressort que G. hirsutum et C. equisetifolia peuvent être utilisés pour la restauration et la valorisation de superficies de terres salées. Par contre, à partir de 46,72 g.l-1, le choix de J. curcas s’impose. Mots-clés : Salinisation, restauration, Casuarina equisetifolia L., Gossypium hirsutum L., Jatropha curcas L., valorisation. ABSTRACT Objective: To contribute to the range of plant species that can be used in the restoration and reclamation of saline lands. Methodology and results: In three (3) independent trials and in a completely randomised design, Casuarina equisetifolia, Gossypium hirsutum and Jatropha curcas young plants were sprayed with NaCl solution at concentrations varying from 0 to 23.36 gl-1 and monitored for two months. Subsequently, these plants were submitted to a toxicity test with concentrations eight times higher. Results show that first two months salt solutions are less harmful for growth and biomass 16521 Faye et al., J. Appl. Biosci. Vol. 160 : 2021 Comportement sous serre de Casuarina equisetifolia L., Gossypium hirsutum L. et Jatropha curcas L. soumis au stress salin. production of G. hirsutum and C. equisetifolia than J. curcas. They have significant effects on litter production, which increases in J. curcas. Conclusion and application of results: The study results may explain why between 46.72 and 186.88 gl-1 NaCl solution is lethal (44 to 100% mortality) for C. equisetifolia and G. hirsutum and not for J. curcas, which does not record mortality. Thus, up to 23.36 gl-1 NaCl concentration, the three species react differently. Thereby, G. hirsutum and C. equisetifolia can be used for the restoration and enhancement of salty areas. On the other hand, from 46.72 g.l-1, it is essential to choose J. curcas. Key words: Salinization, restoration, Casuarina equisetifolia L., Gossypium hirsutum L., Jatropha curcas L., valorisation.

An experiment was conducted to identify effective Frankia strain that established good nodulation for higher biomass production in Casuarina equisetifolia through cross inoculation of Frankia strains from four different hosts viz, C. junghuhniana, c. cunninghamiana, Alnus nephalensis and Myrica gale. The result of plant biomass production and nodulation assay revealed that the superior performance of C. Junghuhniana source over other sources tested; on the other hand A. nephalensis and M.gale showed nil performance, but C.cunninghamiana source average performance over control.
