- Abstract
Part of byproducts synthesized by plants through photosynthesis reach the ground, where are creating selective microenvironments for micro-flora and associations of plant -- microorganisms, being beneficial for plant growth. In this paper, the effect of the root interference area of vines and herbaceous plants and of radicular exudates from vine rhizosphere on microbial community was studied by estimating the present microbial population. Also, by molecular studies, the diversity of microbiological community was assessed.The microbiological study of biological samples was performed by classical and molecular methods. The biological material was represented by microbial communities from rhizosphere and phyllosphere areas of two varieties of vines White Romanian Tămâioasă and Black Romanian Tămâioasă cultivated in a soil that has never been chemically treated. Overall, bacteria had a significant presence in soil samples taken from the interference area of vines and herbaceous plants roots. Actinomycetes quantitatively dominated the root interference area of herbaceous plant with variety White Romanian Tămâioasă. The range of actinomycetes species and leaves microflora was found to be reduced. In this study we have shown that significant growth of microorganisms occurs in the interference area of vine with other herbal plants as a result of the cumulative effect of radicular exudates and that the surrounding microbial community differs among varieties, areas of interference and also is strongly influenced by the levels of tillage and fertilization of soil.
