This study was designed to test the effect of different fractions of ethanolic extracts of young (y) and mature (m) leaves of Serjania lethalis A. St- Hil (Sapindaceae) on sesame (Sesamum indicum L.) seedling growth and metaxylem cells. Crude ethanolic extracts were prepared from the powder of young and mature S. lethalis leaves and fractionated by means of column chromatography. For the seedling growth bioassay, sesame seeds germinated at concentrations of 0.8, 0.4 and 0.2 mg mL-1 were used. After seven days, the lengths of the aerial part and of the primary root were measured. The sesame metaxylem cell growth bioassay was performed with seedlings grown in solutions containing the different fractions in the same concentrations as above. The tested...
