OBSERVATIONS CONCERNING THE BEHAVIOR OF RIBWORT PLANTAINS (PLANTAGO LANCEOLATA) UNDER POWDERY MILDEW (PODOSPHAERA PLANTAGINIS) ATTACK BETWEEN 2013 AND 2014 PUBLISHED

BORCEAN A., Mihaela COLCEA, DAVID Gh
On the last two years, one of the target of our research work from the area of Nera river basin was to determine the diseases of plantains(Plantago sp.) species from Nera river basin. Also it is an attempt to see the dynamics of those pathogens. It is our duty to show from the very beginning that this paper contain data of just two years of research and this is the reason why data statistic interpretation could suffer dramatic changes in the near future, after we bring more observations data for statistic analyze. Regarding to the work method, all observation data were collected during vegetation period of years 2013 and 2014. In this paper there are presented only averages of data collected during the time period mentioned previously. Our observations consist from four separate operations. First operation was to determine in the year 2013 that form the three species of plantains Plantago major, P. minor, and P. lanceolata, the dominant species was Plantago lanceolata the areas with representative populations of Plantago sp.. The second operation was to determine the place and the density of the most representative populations of ribwort and third operation was to see if those plants are affected of some pathogens. The forth operation was to evaluate the attack parameters of each pathogen. The novelty is relatively high because this work provides important data for both agricultural practices (especially for breeding process) and also for local environment protection authorities. Taking in consideration that Plantago sp. plants are used on a relatively large scale for some pharmaceutical and cosmetic industry, it is important to know the infection pressure of the plants pathogens from natural environment. From this point of view we appreciate that the plants from wild flora are considered to be a consistent source for diseases resistance genes in the plant breeding process. Limits of the research are that data from the research are just from two years and greatly influenced by local climatic and soil factors
