The Study of the Climatic Conditions Influence on the Attack Degree of Moniliosis and Red Stain in Plum, Function of Strain and Fertilizers

Increasingly climate change, affects several sectors of agricultural production, one of the most important being the fruit. In this context, this paper is presented the study on the influence of climatic conditions on monilioză attack shoots and red staining on leaves of plum and interaction: climate conditions - foliar fertilization, climatic conditions - variety, four varieties of plum (Stanley, Tuleu timpuriu, Anna Spath, Gras ameliorat) grown in the Somes Plateau, Calacea, County, three experimental years: 2007, 2008 and 2009. Regarding the interaction of climatic conditions - foliar fertilization was found that 2008 was the most favorable terms moniliozei attack on shoots, and variety in the degree of injury was highest (9.41%) is Stanley and lower in 2007 (6.43%). when in fact the values are significantly distinct from the average. If oncerning the shoots moniliosis attack we cannot make a statistical difference on the results it may be noted that the ranking of varieties behavior to moniliosis attack under the application of foliar fertilizationled to the following results: Anna Späth ranks first (7.47 %), then follows Tuleu timpuriu (7.54%), Stanley (7.83%) and Gras ameliorat (7.96%). Polystigma rubrum plant pathogen was observed in maximum values of all the experimental conditions in 2008, the degree of attack on the leaves reaching values of 5.71%. The variety most resistant to staining red leaf plum (Polystigma rubrum) proved to be kind Stanley while the lowest sensitivity of a variety registered variety Anna Späth.
