The identification of rhizospheric microflora under plant variety Triticum aestivum

Abstract

The collection of isolates has been made from rhizosphere of great number of divergent genotypes in order to identify the wheat's rhizosphere microflora. The genotypes were breed on the varietal test in Center for stubble wheat in Kragujevac. We have examined various characteristics on pure isolates e.g. morphological, biochemical, ecological and growing features. Determination was done by Bergey key (1974,1984). Out of 82 isolates there have been identified 39 of them to the species. We have assorted 25 isolates in family of Enterobacteriaceae. Genus Enterobacter and Klebsiella are dominant here. Family Pseudomonaceae (7 isolates) and family Azotobacteriaceae (3 isolates) are also quite present here. We have noticed the qualification of family Bacillaceae (4 isolates).

U cilju identifikacije rizosferne mikroflore kod pšenice urađena je kolekcija izolata iz rizosfere velikog broja divergentnih genotipova pšenice, gajenih na sortnom ogledu Centra za strna žita u Kragujevcu. Čistim izolatima su ispitana morfološka, odgajivačka, biohemijska i ekološka svojstva. Determinacija je vršena po ključu BERGEY (1974, 1984). Od 82 ispitana izolata identifikovano je do vrste 39. U familiju Enterobacteriaceae svrstano je 25 izolata. Dominantno mesto zauzimaju rodovi Enterobacter i Klebsiella. Nađena je velika zastupljenost familije Pseudomonaceae (7 izolata) kao i familije Azotobacteriaceae (3 izolata). Uočena je pripadnost i familiji Bacillaceae (4 izolata).
