Abstract

 

Cambic chernozem soil samples were collected from experimental field of plant breeding discipline, the U.S.A.M.V.B. department in Timişoara. The soil has been sifted through a sieve of 2 mm and placed in polyethylene bags. Thereafter, the soil was treated with two herbicides (tribenuron-methyl and nicosulfuron) in different doses. Samples were incubated for 7 days in a thermostat at 28°C and subsequently, quantitative and qualitativeanalysis of fungal colonies in soil samples was performed. The following fungi species were identified in the batch samples: Fusarium sp., Chaetomium sp., Mucor sp.,Humicola sp., Penicillium sp., Rhizopus sp. and Actinomucor sp. Certain species were found in soil samples treated with tribenuron-methyl and nicosulfuron, using increased doses. Other species had reduced-growth due to their sensitivity to xenobiotics. Still, other species appear in treated variants: Stachybotrys sp., Cladosporium sp., Aspergillus sp.,Penicillium sp. and Fusarium sp. in every experimental variant presented an increasing resistance to the action of xenobiotic substances.

 

Key words: Sulphonylureic herbicide, fungi communities, xenobiotic.
