摘要：Neoteny,i.e.the appearance of reproductive organs already in the juvenile phase of development,was analysed on two-month old shoots growing from amorpha (Amorpha fruticosa L.) roots.The author distinguishes between induced (stimulative) and spontaneous (retention) neoteny.Neoteny is a very complex issue and its early analysis as a property of weed species is only a starting point for its further scientific study and utilization.Neoteny is a genetic and physiological marker in the genotype of a tree individual or the species as a whole.Precocious flowering also contributes to shortening the period of the synthesis of new tree and shrub cultivars.
