Özet

In this study, we evaluated the effect of time (days of mycelial growth) and different doses of potassium bicarbonate (KHCO(3)) on mycelial growth of Sclerotinia sclerotiorum and Rhizoctonia solani by multi regression analysis. All equations produced for mycelial growth of S. sclerotiorum and R. solani were derived as affected by doses and times. As a result of ANOVA and multi-regression analysis, it was found that there was close relationship between actual and predicted mycelial growth of S. sclerotiorum and R. solani. The produced prediction models in the present study are MGS = (a) - (b x dose) + (c x time), where MGS is mycelia] growth of S. sclerotiorum and MGR = (a) + (b x dose) + (c x time), where MGR is mycelial growth of R. solani, a, b and c are coefficients. R(2) values were 0.81 for S. sclerotiorum and 0.75 for R. solani, standard errors were found to be significant at the p < 0.001 significance level.
