Morphological characteristics of the leaf blade and the variety of dill morphotypes

Relevance. Common dill (Anethum graveolens L.) is an annual plant of the celery family (Apiaceae). It has alternated variously repeatedly pinnatisected simple leaves characterized by a number of morphological features including color, presence of waxy bloom, size and density of the final segments, size and shape of the leaf blade. Leaves on different nodes of the same plant can be variable. Environment conditions of plant cultivation also affect some morphological characteristics of the leaf (inc. size of the leaf and its final segments). But, under the same conditions each variety of dill possess a certain set of morphological features that determine the variety identity. In recent years, dill varieties with new morphological features of the leaf blade nave emerged, and it is important to evaluate and classify the existing morphologic diversity of the plant. Methods. Several methods are currently used to describe morphological features of dill leaves structure: developed by VIR (All-Russian Institute of Plant Genetic Resources), UPOV, the plant approbation manual, description of leafy vegetables in “Cultivated Flora" compendium...
