Rhizosphere soil microorganisms are significant factors affecting plant growth, especially that of saline–alkali tolerant plants in the desert ecosystem. We performed high-throughput sequencing order to identifying fungal community structures and their relationships physicochemical properties different layers for plant, Anabasis aphylla, its natural environment. The number unique operational ta...

Chenopodium hoggarense Uotila & C. Chatel., a new species of the family Amaranthaceae s.l. (Chenopodiaceae s.str.) from Hoggar and Tibesti mountains Sahara, in Algeria Chad, is described illustrated. The was found quantities (Ahaggar) 2019. It had been observed there earlier several times, but it confused with vulvaria L. because its similar smell dense cover vesicular hairs. However, differs g...

The present work analyses the airborne pollen dynamic of the atmosphere of Toledo (central Spain), a World Heritage Site and an important tourist city receiving over 2 millions of visitors every year. The airborne pollen spectrum, the annual dynamics of the most important taxa, the influence of meteorological variables and the risk of suffering pollen allergy are analysed. Results of the presen...

The diuretic activity of concentrated ethanolic extract of Aerva lanata (Linn) & Aerva tomentosa Forsk on healthy albino rats were studied with frusemide as reference drug. The urine output increased with concentrated ethanolic extract of Aerva lanata only. In this case the level of electrolytes in urine also increased. But the diuretic activity was mild as compared to frusemide.

The antimicrobial activity of ethanol, petroleum ether, dichloromethane, ethyl acetate, methanol and aqueous whole plant extracts of Aerva tomentosa (Amaranthaceae) were tested against nine human pathogens such as Bacillus subtilis, Enterobactor aerogenes, Escherichia coli and Pseudomonas aeruginosa bacterias and Aspergillus flavus, Aspergillus niger, Candida albicans, Trichophyton rubrum and P...

Tropical leaf vegetables are grown in the tropics and are rich sources of nutrients, particularly minerals, and vitamins (Oomen and Grubben 1978). A number of species and cultivars have been introduced and grown in the continental US on a limited-scale, particularly in the southern region (Lamberts 1993). The US is a major market for tropical and specialty greens and most of the shipments come ...
