HAMDI GÜRAY KUTBAY AND MAHMUT KILINÇ
Abstract
In this Study nitrogen (N), phosphorus (P) and potassium (K) analysis were carried out during vegetative and generative growth periods hi some members of Amaryllidaceae family collected from the Central and East Black Sea Regions. oil the north of Turkey. The above ground parts of plant N ere found to have higher macroelement concentrations as compared to below ground parts during vegetative growth period. However, below ground parts have higher macroelement concentrations during generative growth phase due to "top senescence". In addition to this there were significant and mostly negative correlations between plant and soil macroelement concentrations.
