A modified version of fluctuating asymmetry, potential for the analysis of Aesculus hippocastanum L. compound leaves
My research interest was to create a new, simple and tractable mathematical framework for analyzing fluctuating asymmetry (FA) in Aesculus hippocastanum L. palmately compound leaves (each compound leaf with 7 obviate, serrate leaflets). FA, being random differences in the development of both sides of a bilaterally symmetrical character, has been proposed as an indicator of environmental and genetic stress. In the present paper the well-established Palmer's procedure for FA has been modified to improve the suitability of the chosen index (FA(1)) to be used in compound leaf asymmetry analysis. The processing steps are described in detail, allowing us to apply these modifications for the other Palmer indices of FA as well as for the compound leaves of other plant species.
