Abstract

The purpose of this experiment was to study of the effect of water extract from dry stevia leaves (Stevia rebaudiana Bertoni) on the seeds germination and on the growth and netproductivity of lettuce and cucumber. The experiments were carried out under controlled condition (artificial light). The growth stimulation of seedlings was revealed during the seeds treatment with the initial extract without dilution (at the concentration of basic steviol glycosides – SG – in the extract 1- 1.2 mM). Three foliar treatment of lettuce and cucumber with extracts from Stevia with a concentration of 20-25 μM SG increased the net-productivity of both crops by 29-35%. This effect is apparently due to the presence of Gibberellin-like activity in SG. Water extract from stevia leaves can be recommended as an effective and environmentally safe plant growth stimulator.
