STUDY ON THE ATTACK OF PSEUDOCERCOSPORELLA HERPOTRICHOIDES ON WHEAT STEM BASE UNDER CONDITIONS FROM TMISOARA DIDACTIC RESEARCH STATION PUBLISHEDDiana Velimirovici, Adrian Borcean
Research aim was to test the tolerance of a range of wheat cultivars to infectious pressure of the pathogen Pseudocercosporella herpotrichoides in climatic conditions from Timisoara Didactic Research Station. Stage of research is being characteristic for partial interpretation of experimental data after the first experimental year, in preparation the doctoral thesis. Materials and methods. Experimental field was located in climatic conditions from Timişoara. Technology was the standard applied to this area. The experience was bifactorial. First factor was the cultivar with three graduations (Ciprian, Arieşan and Kristina). Factor B was the nitrogen amount with three graduations (N 50 , N 100 and N 150 ) all three doses were applied on a constant background elements of P 60 K 60 . The novelty is relatively high, work providing important data for agricultural practice in the experimental area, taking in consideration the implications of fungus Pseudocercosporella herpotrichoides in yield amount and harvesting problems in some years. Achievements stage in this field. In this work were carried out research including one of authors, known as the reference and possible reactions of the pathogen depending on local biocoenosis factors, including the competiotin between stem base pathogens. Limits of the research are that data from the fungus Pseudocercosporella herpotrichoides are just after one year bonitation. Practical implications of the research consisted of playing a part of a complex study of strategy in the of wheat protection reference experience. The originality of the work comes from the fact that data are relevant in view of cultivars behaviour under specific conditions. These data are only part of the data submitted for interpretation in the preparation of the doctoral experience of the author. Importance of the paper became from bringing in front of the specialists of one of the topics in the experiences of the author's doctoral preparing, to evaluate the accuracy of techniques addressed. The relevant data, experimental results give an overview of pathogen behavior in relation to experimental conditions.
