correlations - Opis:
- Critical transport velocity, thickness, width, length, angle of sliding friction and weight of small−leaved lime (Tilia cordata Mill.) seeds from five batches, harvested in four neighboring seed regions in Poland, were determined. The values of shape factor, cross−sectional area, volume and density were calculated for each seed. The results were compared using standard statistical methods (simple ANOVA, correlation, single−variable and multivariate regression analysis). The highest correlation was observed between weight of seeds and their thickness and width. Majority of regression equations developed in the study was characterized by a relatively high percentage of explained variation, taking into account the type of experimental material.
