Abstract
In the present study, the effect of cutting origin and indole-3-butyric acid (IBA) concentration and application method on rooting shoot cuttings of Salvia fruticosa Mill. (f. Lamiaceae), Greek sage, was investigated.
The aim was to develop an effective propagation method that could enhance the potential use of the plant in the floriculture industry.
Terminal and basal cuttings were collected from annual shoots of wild or greenhouse mother plants in early May.
They were treated either with dusting powder for soft-wood cuttings Rhizopon (0.5% w/w ΙΒΑ) or their bases were dipped for 1 min in solution IBA (50% ethanol) at five different concentrations, i.e., 0 (control), 500, 1500, 3000 and 4500 mg L‑1. Cuttings were placed for rooting on peat-perlite 1:1 (v/v) in a mist for 2 weeks.
Then, they remained on the greenhouse bench in a semi-shaded location for another 4 weeks.
Regarding cuttings derived from greenhouse mother plants, terminal ones rooted at higher percentage (80%) than the basal (60%), both after treatment with IBA powder, and the highest fresh and dry shoot weight and fresh root weight values were obtained after treatment with IBA powder, too.
To the contrary, cuttings from wild mother plants rooted at highest percentage (80%) when basal and treated with 4500 mg L‑1 IBA, while the highest rooting response for terminal cuttings was 55%. The use of IBA powder resulted to the highest fresh and dry weight of above-ground plant part in basal cuttings, but it reduced their rooting to 50%. As regards time needed for rooting, cuttings from greenhouse plants reached their highest rooting percentage faster (in two weeks) than cuttings from wild plants, which required four weeks.
Therefore, an effective method for commercial propagation of Salvia fruticosa that would enhance use of desirable clones in xeriscaping, could involve terminal cuttings obtained from greenhouse grown mother plants and treated with IBA powder for soft-wood cuttings.
