Zmienność cech morfologicznych liści brzozy brodawkowatej (Betula pendula Roth) w Polsce

Variation in leaf morphology in 9 populations of the silver birch in Poland was investigated. 11 measurements were made on each leaf. Leaf width and length as well as perimeter and area were positively correlated with petiole length. There was also strong positive relationship between perimeter, width and area. Analysis of variance showed significant differences between provenances in most of features of leaf. Provenances Browsk, Chełm, Siedlce were the most similar to each other. Leaves from Augustów had the biggest length but their petiole length, perimeter and area were the smallest
