Abstract

The effect of varied time, nutritional media, and species of fungus on taxonomic characters (L, a, b₁, c, and V) of Aphelenchus avenae was investigated. The effect of these ecological conditions on morphometrics was variable; however, these characters varied significantly with increased time, decreased nutritional media, and species of fungus. The greatest number of morphometric changes occurred with increased time, and the fewest with species of fungus. With changing environmental conditions, “V” values were the most stable character.
