Objective: Our aims were to identify which medicinal plants in the East- Mazandaran used for gastro intestinal problems and how the indigenous people treat their gastro intestinal problems. Methods: An investigation w...
Trees are the most important biological elements of forest ecosystems. The variability of the tree species composition inhabiting in the Oriental beech forest, not only forms different forest types but also has a remarkable impact on the species diversity of forest floor plants, due to the existence of trees in the overstory layer. In this research, forest types of an an Oriental beech were ide...
to study the effect of different arbuscular mycorrhiza fungi on growth performance and water absorption efficiency of osteospermum, a factorial experiment based on a randomized complete block design was conducted in greenhouse. a total of 22 different species of mycorrhizal fungi in symbiosis with the plant studied in this experiment. the results showed that mycorrhiza fungus glomus mossea ca a...
During an investigation on pteridophytes (ferns) of Guilan province (N Iran), 402 specimens were studied. Of these, 44 species, under 21 genera, belonging to 13 families, were identified. Based on the approved instruction given by the "International Union for the Conservation of Nature and Natural Resources (IUCN)", after performing the filtering stage, 17 species were identified as endangered...
biodiversity plays a crucial role in stability and productivity of natural ecosystem. the main goal of this research was to classify ecological groups in steppe rangeland and investigate their relationships with plant diversity indices. therefore, fifty different land unit tracts (lut) were identified in khod-neuk basin, yazd province, iran, in 2010. vegetation and soil samples were taken in th...
The green synthesis of metallic nanoparticles is an active research area in nanotechnology. In the present study, antioxidant potential, total reducing capacity and silver nanoparticles (Ag NPs) synthetic potential of methanolic leaf extracts of seven plant species were evaluated and compared. Antioxidant capacity, expressed as µmol Trolox equivalents g-1 DW (µmol TE g-1 DW), ranged from 116.0 ...
Beekeeping is one of the promising ventures for economically poor families in Nepal. Knowledge about the bee flora of a certain area is very crucial for the farmers. A study was conducted in mid hills of Central Nepal during 2003-04 and 2008-09 to monitor the common plant species visited by bees with their visiting time and seasons. The flowering period of those plant species were also observed...
Introduction: Continued search for safer and more effective phytochemicals to be used in chemotherapy is ultimate goal of pharmacologists. Cancer chemoprevention with natural phytochemical compounds is an emerging strategy to prevent, impede, delay, or cure cancer. This study aimed to review the research conducted on anticancer ingredients extracted from native plant species of Iran. Methods: ...
Species of Phyllosticta are important group of pathogenic and endophytic fungi that are reported from various crop plants, ornamental and non-fruiting plants. These fungi cause several diseases such as leaf and fruit spots and fruit rot. In order to identify Phyllosticta species in Guilan province, several collections were examined around the region. Altogether 14 taxa were isolated from differ...
a phytochemical screening of fifty five iranian plants belonging to 21 families was carried out. a qualitative phytochemical analysis was performed for the presence of alkaloids, tannins, saponins and flavonoids. the medicinal uses of these plants are also reported.
