Plant age and chromatographic pattern in Potentilla

摘要

Phenolic compounds in apomictic biotypes of Potentilla argentea, P. canescens and P. norvegica were studied by means of thin-layer chromatography. Leaf samples were taken from plants cultivated in a growth chamber at intervals of one month. For each biotype the chromatographic pattern was changing, especially during the earliest stages of growth. Other observations indicate that climatical conditions may also affect the chromatograms.
