Plantlets grown in conventional tissue culture systems usually encounter physiological and anatomical abnormalities including inability to photosynthesize, low chlorophyll content, open stomata, lack of a cuticle layer in the leaf, abnormal xylem parenchyma etc. Photoautotrophic and photomixotrophic systems could diminish these problems. The purpose of this study was to increase the chlorophyll...

Cajanus cajan (L.) Millsp is one of the second most dietary legume crops. The leaf extracts may be used as a potential source of natural antioxidant. The ash values, extractive values, total phenolic and flavonoid content, in vitro antioxidant activity of various leaf extracts as well as anatomical investigation of Cajanus cajan were carried out. Physicochemical parameters such as total, acid-i...

Many plants have been known to synthesize active secondary metabolites to protect themselves from microbial attack which have potential therapeutic applications. The soxhlet extracts of leaf and stem of Iresine herbstii using ethanol, acetone, dichloromethane and petroleum ether were investigated for their phytochemical and antibacterial activity against pathogenic bacteria and compared with th...

The effects of irrigation water salinity on growth, chlorophyll contents, proline and nutrients accumulation and K/Na ratio in three walnut cultivars was investigated. Three irrigation water salinity levels with electrical conductivities of 1,5, 3, and 5.0 dS/m and tap water as a control treatment were used in a randomized design with four replications. Irrigation practices were realized by con...

Photosynthetic light acclimation of leaves can result from (i) changes in mass-based leaf nitrogen concentration, Nm, (ii) changes in leaf mass:area ratio, Ma, and (iii) partitioning of total leaf nitrogen among different pools of the photosynthetic machinery. We studied variations in Nm and Ma within the crowns of two peach (Prunus persica L. Batsch) trees grown in an orchard in Portugal, and ...

The purpose of this study was to test flower and leaf extracts against some gram-positive and gram -negetive bacteria. Two different microbial tests were performed; extract antibiogram, and determination of MIC (minimum inhibitory concentration) of extracts. The results showed that antimicrobial activities of extracts were notable on a wide spread of bacterias, especially on the choosen bacteri...

Due to the emergence and spread of malaria parasite with resistance to antimalarial drugs, discovery and development of new, safe, and affordable antimalarial are urgently needed. In this respect, medicinal plant extracts are targets to optimize antimalarial actions and restore efficacy of standard antimalarial drugs. The present study was aimed at determining the antimalarial activities of Gyn...

Medicinal plants are an important source of substances which are claimed to induce anti-inflammatory and antioxidant effects. The leaves of the olive tree (Oleaeur opaea) have been used for medicinal purposes since ancient times and research has suggested that olive leaf extracts have antimicrobial and antimutagenic properties. In this study, Olive leaf aqueous extracts were screened for their ...

The extracts of the leaves and stem bark of anacardium occidentale were screened for phytochemically for the presence of secondary metabolites and for in vitro antibacterial activity. The phytochemical screening revealed the presence of alkaloids and tannins. The methanol and aqueous leaf extracts and the methanol extract of the stem bark were tested against Klebsiella pneumoniae, Staphylococcu...
