background: the antioxidant components have been identified in some pine species. antioxidant properties of proantocyanidins reduce free radicals induced by dna fragmentation and lipid proxidation and also proanthocyanidines could curb lipid peroxidation. objective: in this study, we analyzed different parts of pinus eldarica (bark, seed and needle) and assessed their antioxidant contents. meth...

Plant invasions can change soil biota and nutrients in ways that drive subsequent plant communities, particularly when co-invading with belowground mutualists such as ectomycorrhizal fungi. These effects can persist following removal of the invasive plant and, combined with effects of removal per se, influence subsequent plant communities and ecosystem functioning. We used field observations an...

The genus Pinus is represented for woody plants which has big economic importance. There are reports that some mycorrhizal fungi associated with this plant produce chemistry compounds with biological activities. The aim of this study was to evaluate the association between genus of fungi found in Pinus, biological activities detected and substances isolated. In this way, it was realized a syste...

Fossil records indicate that the genus Pinus L. split into two subgenera by the Late Cretaceous, although subgenus Strobus (D. Don) Lemmon is less well documented than subgenus Pinus L., especially in eastern Asia. In this paper, Pinus maomingensis sp. nov. is established based on a compressed seed cone from the upper Eocene of the Maoming Basin of southern China. This species is attributed to ...

Aprostocetus pinus sp. nov. (Chalcidoidea: Eulophidae) is newly described as a leaf bud and microstrobilus pest of Pinus massoniana (Pinales: Pinaceae), an important afforestation species in southeast China. Both sexes of the parasitoid are described and illustrated. 

Balanites vietnamica is described as a new species from Nui Chua National Park in Ninh Thuan province, Vietnam. It morphologically close to and has been misidentified B. roxburghii but actually differs many vegetative reproductive characteristics. The taxon found narrowly endemic the semi-arid Phan Rang region its distribution area much reduced. described, illustrated with field photographs of ...

Introduction Pinus taeda stands for productivity and quality of its timber [1]. Researches using biotechnology are of great importance and have been applied to the improvement of its timber and plantation [2]. The main method of Pinus propagation is by seeds, once the minicuttings depends on the season of the year or depends of juvenile material [3-5]. Thus, researches on micropropagation of Pi...

Diplodia scrobiculata, a latent pathogen of Pinus spp. and other conifers with a limited distribution in the United States, Mexico and southern Europe, has not been reported previously in the southern hemisphere. This is unlike its close relative Diplodia pinea that is found in most parts of the world where pines are native or have been introduced. During an intensive D. pinea survey conducted ...

Pine wilt disease (PWD) constitutes a serious threat to pine forests. Since development depends on temperature and drought, there is a concern that future climate change could lead to the spread of PWD infections. We evaluated the risk of PWD in 21 susceptible Pinus species on a global scale. The MB index, which represents the sum of the difference between the mean monthly temperature and 15 wh...
