The aquatic fern Azolla, a small-leaf floating plant that lives in symbiosis with a nitrogen fixing cyanobacteria (Anabaena), is an outstanding plant, thanks to its high biomass productivity along with its tremendous rate per unit area for nitrogen-fixation. The present study investigates the potential growth of Azolla in secondary effluents for removal of COD, phosphorus, and nitrogen. Resul...
Experiments were conducted to determine the influence of Chlamydomonas sp. on nitrogen fixation (C(2)H(2) --> C(2)H(4)) in Azolla filiculoides and on the nitrogen fixation and growth of free-living Anabaena azollae 2B organisms. Inoculation of azolla medium with Chlamydomonas sp. was associated with decreased nitrogenase activity in A. filiculoides and with increases in the density of a fungal ...
one of the important mechanisms utilized by the plant growth promoting rhizobacteria (pgpr) is lowering of ethylene levels by the 1-aminocyclopropane-1-carboxylic acid (acc) deaminase enzyme. the mechanism facilitates plant growth and development in the stress conditions. pgpr containing acc deaminase can promote plant growth under stress and overcome the harmful effects. the study aimed to scr...
Abstract. The use of biofertilizers based on plant growth promoting (PGP) bacteria is a promising direction in agri-biotechnology. purpose was to evaluate the PGP-attributes Bacillus sp. and reveal morphophysiological features rapeseed (Brassica napus L.) when inoculated with these rhizobacteria. Methods. ability strain TO15c isolated from rhizosphere Taraxacum officinale Zack's nitrogen-free m...
In order to evaluate the effects of biofertilizers and nitrogen application on oil, yield and its components in spring rapeseed Var "Hayola 401", a field experiment was carried out by a split plot design based on a randomized complete block design with 4 replications, in Agricultural Research Station ( Dr. Nakhjavani) of Urumia during 2007- 2008. The main plot included of three levels of nitro...
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
it is definitely necessary to understand the concept and behavior of causation of life insurance policies and its determinants for insurance managers, regulators, and customers. for insurance managers, the profitability and liquidity of insurers can be increasingly influenced by the number of causation through costs, adverse selection, and cash surrender values. therefore, causation is a materi...
Chemical seed treatment, inoculation, and co-inoculation of winter bean combined with nitrogen doses
Faced with the contrasting results of inoculation and co-inoculation in bean crop, an experiment was carried out pots, objective evaluating performance plant treatments inoculated or co-inoculated Rhizobium tropici Azospirillum brasilense, via seeds, without chemical treatment fungicide insecticide, combined 4 top-dressing nitrogen doses (0, 30, 60, 120 kg ha-1), a ‘Latossolo Vermelho-Amarelo d...
the debate whether esp teachers need to have knowledge of the specialized field they are teaching has been an issue in the literature over the last two decades. the aim of conducting this study was to explore iranian learners’ and instructors’ beliefs and attitudes concerning the role of specialized knowledge in teaching esp classes. a seventeen item questionnaire was administered to 400 esp le...
