Abstract
Different effects of fasciation on the structure of blastozones and ultimately on the morphology of the plants of the two families investigated was detected. The results of this study demonstrate that in Arabidopsis thaliana phyllotaxis changes, leading to the formation of whorled leaf aestivation (two or four leaf in the whorl). We also demonstrated that in Pisum sativum the number of folioles of a compound leaf increased, the number of stipules also increased, and stipules can grow together and form a structure similar to the sheath of Gramineae. Our results demonstrated that a common manifestation of fasciations in Arabidopsis and Pisum is the formation of a flattened meristem, which extended along the same line (axes of fasciation).
