Cutting type and IBA treatment duration affect Teucrium fruticans adventitious root quality
2014
Root development of stem cuttings of Silver Germander (Teucrium fruticans) was investigated in relation to cutting type and indole-3-butyric acid (IBA) treatment. Terminal cuttings of a clone grown in Sicily were trimmed to three types: terminal cuttings with apex (TWA), terminal cuttings without apex (TWOA) or sub-terminal cuttings (ST). To verify the cutting response to exogenous auxin, cuttings were dipped to a 2.0 cm depth in a 0.5% indole-3-butyric acid solution for 0, 5 or 7 minutes. Overall percent survival was 97 to 98%. Rooting percent, root number and root length were affected by cutting type and indole-3-butyric acid treatment. In general, TWA cuttings demonstrated a higher capac…
CHEMICAL AND BOTANICAL CHARACTERIZATION OF A ROSMARINUS OFFICINALIS L. BIOTYPE FROM SICILY
2006
Rosemary (Rosmarinus officinalis L.) is widely cultivated all over the world as ornamental and aromatic plant. Today, the interest towards its cultivation is strongly arising, due to the many biological activities exerted by the essential oil extracted from its leaves and flowers. Which compounds confer to Rosemary's essential oil its properties is still unclear, but it seems likely that these effects must be attributed to a mixture of different principles, acting contemporarily and synergically. The diverse composition of the essential oils of Rosemary's ecotypes coming from different geographical areas could be the reason of their various level of activity. With the aim of obtaining furth…
Volatile Constituents ofTeucrium poliumL. from Turkey
1998
Abstract The volatile constituents obtained from the aerial parts of Teucrium polium were analyzed by GC and GC/MS. The oil was found to contain 37 components, of which 30 were identified. The major constituents were β-pinene (18.0%), β-caryophyllene (17.8%), α-pinene (12.0%), caryophyllene oxide (10.0%), myrcene (6.8%) and germacrene-D (5.3%)
Micropropagazione di Thymus capitatus
2011
Thymus capitatus is a compact woody shrub, endemic to the Mediterranean region, with attractive pink flowers. Although conventional vegetative propagation of T. capitatus is currently used, micropropagation could be effective for rapid mass propagation of selected clones and would preserve wild plants. Shoot tips of T. capitatus cultured on a gelled MS medium, supplemented with 0.4 mg l-1 2-iP, were used as primary explants to establish in vitro culture. Axillary shoots produced on uncontaminated explants were excised and subcultured to increase the stock of shoot cultures. To determine the optimal medium for shoot multiplication, increasing concentrations (0, 0.4, 0.8, 1.6 e 3.2 mg l-1) of…
