Antolysis (from the Greek. Ánthos - flower and lýsis - destruction, dissolution) - the pathology of the process of "flower resolution", often accompanies the phenomenon of terry. In double flowers, petals , stamens , and sometimes pistils increase in number; in this case, characteristic transformations of one part to another occur, which allows one to find out the morphological significance of each part and their origin.
Description and examples
Stamens most often turn (all or only external) into petals, less often into pistils. These latter often remain unclosed, turning into typical, often green, leaves. All this serves as evidence that both pistils and stamens are mutated leaves . During antholysis, the axis of the flower lengthens, and all its other parts move apart and turn into green leaves, which can be observed, for example, in the larkspur . Antolysis is an important proof of evolution in general, as it shows that the modern parts of the flower evolved from mutated leaves . Antolysis as a pathology is also studied by the science of deformities ( teratology ) [1] .
