We study the restoration of coal mining dumps through reforestation in forest-steppe zone Kuzbass. 3 main forest-forming species ( Betula pendula, Pinus sylvestris and Populus tremula ) 11 accompanying tree were involved formation forest stands. The was pendula . amount renewal found to be 10.7, 3.1 1.0 thousand pcs/ha sites with favourable, moderate favourable unfavourable environmental condit...

Abstract Background Imprudent use of antimicrobial drugs has resulted in the microbial resistance among known microbes and hence we foresee a pressing need towards development novel, low-cost, high potent antimicrobials which should be munificent by nature. In pursuit above, phosphoric acid activated low-cost carbon was produced from renewable phytomass precursor viz., leaves Vitex negundo L. p...

Title of Dissertation: ECOLOGICAL DYNAMICS OF MACROLEPIDOPTERA FEEDING ON BOX ELDER (ACER NEGUNDO L.) Eric Michael Lind, Doctor of Philosophy 2008 Dissertation Directed by: Pedro Barbosa Department of Entomology Understanding species abundances and distributions is a major goal of ecology. While manipulative experiments can reveal mechanistic properties of interactions among a small number of s...

Over 90% of the insect damage to cowpea seeds is caused by Callosobruchus maculatus. Although, many chemicals have proven their efficacy against C. maculatus, they adversely affect natural environment. Death non-targeted species which are enemies other pests and development resistance possible. Therefore, current study was conducted determine effect plant leaves Murraya koenigii (“Karapincha”),...

The purpose of this work is to comparatively assess pollen viability five plant species growing in different areas the city Aktobe, Kazakhstan (N 50°18´, W 57°10´). Pollen was assessed through iodine staining on samples grains harvested between April and June 2017 from 100 plants 5 industrial zones, parks, along highways: Ulmus laevis Pall., pinnato-ramosa Dieck., Acer negundo L., Syringa vulga...

In this study, two-year-old bare-root Acer negundo and pseudoplatanus seedlings were grown indoors (control vs. drought-stressed) outside the hoop house to examine leaf gas exchange parameters in late growing period. Besides morphological features, several parameters, such as net photosynthetic rate (Anet), transpiration (E), stomatal conductance (gs), intercellular CO2 ambient (Ci/Ca), water u...
