ALVAREZ-HERRERA, Javier Giovanni; RODRIGUEZ, Santos Lusardo  e  CHACON, Edinson. Effect of different sizes of stem cuttings and substrates on the propagation of rosemary (Rosmarinus officinalis L.). Agron. colomb. [online]. 2007, vol.25, n.2, pp.224-230. ISSN 0120-9965.

Rosemary presents difficulties in sexual propagation because it does not flower easily and, when it does, the seeds present low viability. Likewise, the rooting of stem cuttings of rosemary is slow. The objective of the present work was to evaluate the effect of different sizes of stem cuttings and substrates on the propagation of rosemary. Three stem cuttings sizes of 6, 8 and 10 cm were taken from the apical part of one year old plants and rooted in 4 different substrates: black soil (SN), burn rice husk (CAQ), mixture of burn rice husk and black soil in 1:1 volume proportion (M), and Canadian peat moss (TRC), making a total of 12 treatments with 4 repetitions each one. The dry and fresh weight of stems and leaves were affected mainly by the substrate type. The size of stem cuttings affected proliferation of roots and stems. The TRC had a significant effect on fresh and dry weight of rosemary plants. The Canadian peat moss accumulated a high moisture contents making the highest relative water content (CRA) in this substrate. The fresh and dry weight of roots was influenced mainly by the size of stem cuttings. The best size of stem cuttings in rosemary propagation was 10 cm in all substrates. The substrate M was the second best one and had a significant benefit when compared with SN and CAQ.
