Dynamics of Ontogenesis in The Phytosphere: Fluctuation of the Asymmetry of The Birch Leaf (Betula Pendula)

The method for measuring the morphological parameters of birch (Betula Pendula) leaves with-out cutting them in the dynamics of ontogenesis has been refined, the asymmetries and fluctua-tions of leaves have been compared, and patterns of oscillatory adaptation in the dynamics of ontogenesis have been identified. First, a sheet is selected, marked with a white thread with a tag (birch and leaf number). Before photographing, a transparent mesh (2×2 mm) is placed on the front side of the growing leaf so that the middle line along the mesh coincides with the main vein of the leaf. The palette sheet is then photographed with a digital camera with a photo stor-age function. On the computer, the photo is cropped and enlarged for measurements on the screen up to A4 format. The measured 25 accounting birch leaves were divided into groups ac-cording to the nature of their behavior in ontogenesis: 1) left asymmetry, when the left side of the leaf is predominant; 2) tendency of the accounting sheet by fluctuation from left to right asymmetry; 3) transition from left to right asymmetry; 4) transition from right to left asymmetry; 5) tendency of the growing leaf by fluctuation from right to left symmetry; 6) right asymmetry. New sheet parameters have been introduced: absolute asymmetry; relative asymmetry. The “+” sign will show left asymmetry, and the “–” sign will show right asymmetry. The wavelet signal identification method for each leaf revealed up to 6-7 quanta of behavior in ontogenesis in the form of wave equations. Birch is distributed throughout the Northern Hemisphere, so the phyto-sphere can be studied by fluctuating asymmetry of leaves in ont ogeny in different geograph-ical coordinates of the cities of the world.
