Pseudomonas SP. in tomato rhizosphere (Lycopersicon esculentum Mill)

Abstract

The aim of research is determining the presence and number of Pseudomonas sp in tomato rhizosphere. The tests were conducted on a tomato hybrid Big Beef grown on the soil type pseudoclay-hard. Bacteria isolation was conducted in the root zone 20-40 cm. Rhizosphere was separated mechanically on rhizospheral soil, root (unsterilized) and root (sterilized). Tripofan Medium was used for isolation of Pseudomonas sp. from the soil. In the obtained results biochemical and morphological characteristics were conducted. Results analysis was conducted with suitable statistical methods. Based on the results, we can conclude that the number of bacteria in different variants is statistically extremely significantly different on Tripofan Medium and statistically significantly different on Nutritious agar.
