A comparative study of phenolic, anthocyanin, flavonoid compounds and antioxidant properties of medicinal fruit of Vaccinium arctostaphylos L. (case study: three regions of Talesh, Iran)

Plants are rich sources of phenolic compounds (flavonoids, tannins and anthocyanins) that are considered as the most important natural antioxidants. Vaccinium arctostaphylos is a shrub that belongs to Ericaceae family and has long been used in Iran traditional medicine due to its effects such as reducing blood glucose and pressure. The main metabolites of V. […]

Effect of crude oil pollution on the rhizosphere microbial communities of Mangifera indica L and Elaeis guineensis Jacq in Rivers State, Nigeria

This study investigated the effect of crude oil pollution and remediation on the fungi and bacteria communities of M. indica and E. guineensis rhizospheres using three sites – Unpolluted Site (UPS), Polluted and Treated Site (PTS), and Polluted and Untreated Site (PUS).

Lipid peroxidation, oxidative stress and respiratory metabolism alteration in the freshwater ciliate Paramecium tetraurelia exposed to cypermethrin, a pyrethroid insecticide

Oxidative damage by increased production of reactive oxygen species have been involved in the toxicity of several pesticides. Thus, the aim of this study was to investigate the effect of cypermethrin, a widely used type II pyrethroid, on the oxidative stress biomarkers and the respiratory metabolism of Paramecium tetraurelia. Different concentrations of the insecticide (0.05, […]

Comparative influences of manures and NPK fertilizer on growth performance, root yield and reserpine content of Rauvolfia spp

The study revealed the growth performance, root yield and reserpine content in the root part of R. serpentina and R. tetraphylla under four different treatment regimes (T1,T2, T3, T4). Three types of cutting like root, root-stem junction and stem of 2 to 2.5 years old plants of both the species were used. It was concluded […]

Contribution to the study of coastal floristry biodiversity in Oran

According to Eurostat report data (EU Statistical Office) the enormous impact of tourism on ecosystems would be one of the most important causes of biodiversity degradation in the Mediterranean countries. The Red List of IUCN (International Union for Conservation of Nature) records today some 16120 endangered species in the world. In this context we conducted […]

Pollen morphology of Convolvulus L. populations in Markazi Province, Iran

Pollen morphology has been extremely useful in clarifying systematic relationships within the plant taxa. Moreover, palynology of the species and subspecies could have taxonomic value as the supporting evidence to the morphological and phylogenetic studies. Palynological studies of 12 collected Convolvulus populations from Markazi Province of Iran were done using light and scanning electron microscopy […]

Antagonistic effect of Trichoderma harzianum against Phytophthora infestans in the North-west of Algeria

The oomycete, Phytophthora infestans is considered one of the most important pathogens of potatoes and tomatoes worldwide. A total of 38 Phytophthora infestans isolates were obtained from leaves, tubers and stems of infected crops of potato and tomato in different regions of the North West of Algeria in 2010, 2011 and 2012. Based on morphological […]
