Abstract :Sternbergia lutea insert ignore into journalissuearticles values(L.); Ker-Gawl. ex Sprengel and Narcissus tazetta L. subsp. tazetta are two autumnal geophytes belonging to Amaryllidaceae. N. tazetta subsp. tazetta consist of some vomitory alkaloids. S. lutea has also important alkaloids too. In this study nitrogen insert ignore into journalissuearticles values(N);, phosphorus insert ignore into journalissuearticles values(P); and potassium insert ignore into journalissuearticles values(K); analysis were carried out in two taxa during vegetative and generative growth phases and the results belonging to vegetative and generative growth phases were compared with each other. As a result of these analysis macroelement concentrations are higher during generative growth phase in under ground parts due to `top senescence`.
