The plastic variability, shape and asymmetry of the leaf plates of meadow clover (Trifolium pratense L) depending on various doses of fertilizer and soil cultivation methods were studied. A correlation between the index of plastic variability and the value fluctuating asymmetry was obtained (r = 0.23-0.63; p <0.05). Using the geometric morphometrics, the presence of directional asymmetry was confirmed, and a highly statistically significant variation in the shape of the sheet plate was obtained. In only one sample, a pure fluctuating asymmetry was obtained; in remain cases – a mixture of two types of asymmetry. The authors explain the effect of the declining developmental stability by a low dose of fertilizer, as well as a crop rotation scheme with a relatively low content of trace elements in the soil. A high dole of directional asymmetry verified the influence of genotypic variation on the asymmetry and shape of leaf blade and, therefore, a high dependence of phenotypic variation on the genotype.
