study of soil and plant relationships is nessesery for ecological- based and appropriate management. the objective of this study is to determine the influence of edaphic properties on haloxylon persicum growth and also, indentifing growth limiting soil properties for saxaul. the study was performed through the stratified random sampling and 3 sites were selected as follow: planted strong saxaul...

The effect of mesoporous titanium dioxide nanoparticles on germination traits black saxaul seeds (Haloxylon aphyllum (Minkw.) Iljin) under drought stress

Abstract. The purpose is to study the features of adaptive reactions pigment system plants in stress conditions Astrakhan region. In role diagnosing state plants, physiological and biochemical indicators are used, which reflect body's ability adapt changing environmental conditions. Methods. studies, methods observation, description objects study, spectrophotometric determination quantitative c...

The harsh climate of the arid zone determines several biological features in black saxaul plantations. Therefore, study growth and condition artificial plantations, depending on use physiologically active moisture-absorbing substances biostimulants, is particular practical importance. In Moinkum sands Zhambyl region (Kazakhstan), observations development places where biostimulants were used con...

Haloxylon aphyllum (Minkw.) Iljin is a treelike shrub from the Chenopodiaceae family with thick, gnarled, highly branched trunk dark gray bark. It propagated by seeds. The most typical conditions of natural habitat are valley-like depressions ridges and hollows hilly sands, valleys channels old rivers, often more or less close groundwater occurrence, as well takyrs takyr-like serozem soils. Bla...

Cadmium can be found in wastewater in high concentrations and can cause dangerous effect on aqueous environment and human health. At present, many methods have been used to heavy metals removal. Among this clean up techniques, adsorption techniques by using low-cost adsorbent are more considerable. In this study, batch adsorption experiments were conducted for removal of cadmium ions from a...

black saxaul (haloxylon aphyllum) is one of the best options for rehabilitating drought affected desert lands. the species is remarkably adapted to the central dry environment ofiran and a major source of raising pasture productivity of the areas. progenies of 25 randomly selected black saxaul trees from four populations of the species were studied in a randomized complete block design with thr...

The article provides information on large degraded areas in almost all areas, of which 17.5 million hectares dry natural pastures are allocated for cattle breeding out 32 desert and semi-desert Uzbekistan. It is also noted that 40% have to varying degrees, the average productivity has decreased by 20-30%, 8.0 should be improved first. To improve condition pastures, authors it possible increase ...
