Phyllotaxis of vegetative shoots of anagallis arvensis L. treated in vitro with 6-benzylaminopurine

摘要

Application of 6-benylaminopurine (BA), a synthetic cytokinin, to the growth medium in vitro stimulates the formation of adventitious shoots on stem explants of Anagallis arvensis. They regenerate from dedifferentiating epidermal cells of stem internodes. The process starts from peiclinal and anticlinal divisions in a few of neighbouring cells. The amount of adven- titious shoots increases with an increasing BA concentration.
