Evaluation of size and shape correlation of the leaf blade in Polygonum aviculare L.

The correlation between the size and shape of the leaf blade of Polygonum aviculare L. was investigated. Among the considered shape indicators, the indicator of the relative location of the widest part is most correlated with the size of the leaf blade. Indicators of the width of the leaf blade are more correlated with indicators of the shape of the leaf blade than indicators of length. At the same time, there was no strong correlation between the size and shape of the leaf blade of P. aviculare.
