Abstract Haloxylon ammodendron is an excellent windproof and sand-fixing species whose shrubs are widely cultivated in arid desert areas of northwest China but now at risk degradation shrinkage. Using the chlorophyll fluorescence image analysis technique, response photosystem II (PSII) photochemical efficiency non-photochemical quenching capacity to sediment-carrying wind sand-free (both 12 m s...

Podophyllotoxins represent an important and unique position among natural products. They serve as the starting material for the semi-synthetic anticancer drugs etopside and teniposide, so considerable attention has focused on the availability of these aryltetralin lignans. Linum is one of the genera, with some reports on the presence of podophyllotoxin and related compounds, such as L. album, L...

the genetic diversity of 20 iranian populations of bunium persicum has been evaluated with random amplified polymorphic dna (rapd) and amplified fragment length polymorphism (aflp) markers. fresh leaves of seedlings from each population were used for genomic dna extraction. analysis of banding patterns of 15 rapd primers and 17 aflp primer combinations, revealed 192 (86%) and 228 (75%) polymorp...

Drought has become a serious environmental problem affecting people all around the world as result of rising atmospheric pollution and global warming. Through symbiosis with Arbuscular mycorrhizal fungus (AMF), plants may mitigate impacts drought stress on growth development well physiological metabolism. As pioneer plant for windbreak sand fixation, between AMF Ammodendron bifolium can improve...

In this study, morphometric measurement, meat yield, moisture, pH, protein, fat, fatty acids and ash content were determined in a total of 102 (15 female 87 male) freshwater crab (Potamon persicum Pretzmann,1962) caught from Aşağı Yukarı Çay Pertek, Tunceli. Meat yield male crabs found to be as 12.75±0.38% 10.93±0.32%, respectively. It has been observed that moisture protein amounts higher than...
