Shoot Systems of Solanum dulcamara L.

Abstract

On the basis of biomorphological analysis of Solanum dulcamara, four ecobiomorphs of this plant are identified and described. They are a semi-woody vine, a subshrub with ascending shoots, a root sucker subshrub, and short-lived plants of vegetative origin. The structural units of individual plants, the sympodial shoot axes, are characterized by three variants of shoots: monocarpic renewals and sylleptic, vegetative sylleptic shoots with an incomplete cycle of development. The structural and functional organization of shoots and the development of sympodial axes in different ecobiomorphs, ensuring the ecological plasticity of S. dulcamara, are described.
