Abstract
In the present study, the effect of substrate type and fertilization on growing rooted cuttings of five wild species of sage found in Greece, Salvia fruticosa, S. officinalis, S. pomifera ssp. pomifera, S. ringens and S. tomentosa was examined, aiming to develop an effective nursery-cultivation method, for their introduction to the horticultural industry.
Rooted cuttings were transplanted in various substrates of peat:perlite (1:1, 2:1 or 3:1, v/v) in plastic pots, and were fertilized once a month with 2 or 4 g L‑1 water-soluble fertilizer (Nutrileaf 60, 20-20-20). Plants were maintained for four months (June to September 2019) in a greenhouse and their final height and axillary-shoot number and length were recorded.
In S. pomifera ssp. pomifera, plants fertilized with 4 g L‑1 were taller than those fertilized with 2 g L‑1, regardless of substrate.
High fertilization caused extreme elongation of the central shoot in S. tomentosa resulting to plant bending.
In the other three species, there were no differences in central shoot length (plant height) among treatments.
More axillary shoots were formed by plants fertilized with 4 g L‑1 in S. fruticosa and S. pomifera ssp. pomifera, by plants cultivated in peat:perlite 3:1 in S. ringens and by all treatments, excepting cultivation in peat:perlite 1:1 and fertilization with 2 g L-1, in S. tomentosa. Generally, there were no differences among treatments in axillary shoot length, excepting S. tomentosa, in which the longest axillary shoots were produced by plants in peat:perlite 2:1. Although all species grew satisfactorily regardless of the experimental treatments, fertilization with 2 g L‑1 could be suggested to produce more compact plants.
