Modeling of the effect of potassium bicarbonate on sclerotial germination of sclerotinia sclerotiorum in vitro by multi regression analysis

Özet: Bu çalışmada çoklu regresyon analizi ile farklı potasyum bikarbonat (KHCO3) dozları ve zamanın Sclerotinia sclerotiorum’un sklerot çimlenmesi üzerine etkileri değerlendirilmiştir. S. sclerotiorum’un sklerot çimlenmesi için üretilen eşitliğin zaman ve dozlar tarafından etkilediği görülmüştür. ANOVA ve çoklu regresyon analizi sonucuna göre S. sclerotiorum’un sklerot çimlenmesinin gerçek ve tahmini değerleri arasında yakın bir ilişki bulunmuştur. Elde edilen tahmini modelde SG= (a) - (b x doz) + (c x zaman), SG S. sclerotiorum sklerot çimlenmesi, a, b ve c katsayılardır. R2 değeri 0.80 olarak bulunmuştur.

Çoklu regresyon analizi ile sclerotinia sclerotiorum sklerotlarının çimlenmesi üzerine potasyum bikarbonat’ın etkisinin modellemesi

Abstract: In this study, we evaluated to effect of days and different doses of potassium bicarbonate (KHCO3) on sclerotial germination of Sclerotinia sclerotiorum by multiple regression analysis. The equation produced for sclerotial germination of S. sclerotiorum was derived as affected by doses and days. As a result of ANOVA and multiple regression analysis, it was found that there was close relationship between actual and predicted sclerotial germination of S. sclerotiorum. The produced prediction models in the present study are SG= (a) - (b x Dose) + (c x Time) where SG is sclerotial germination of S. sclerotiorum, a, b and c are co-efficiencies. R2 value was found as 0.80.
