الملخص EN

Gerbera (Gerbera jamesonii L.) belongs to family Asteraceae.

Foliar application provides nutrients to plants by mist in a straight line onto foliage and flora.

The current study is an attempt to observe the effect of foliar application of Glycirrhiza glabra L.

root extract on potted Gerbera using five levels of liquorice root extractions (0, 3, 5, 7 and 9) g.l-1.

Two sprays that are made on liquorice root extract are sprayed on Gerbera plants in two spraying intervals: the first time was after 15 days of transplanting and the second time was after 30 days of the first time of spraying.

In general the results showed augmentation in studied plant characteristics (number of branches per plant (NB), number of leaves per plant (NL), number of Flowers per Plant (NF) ,flower diameter (cm) (FD), stalk length (cm) (SL), stalk diameter (cm) (SD) and vase life (day) (VL) with increasing liquorice root extract levels.
