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…

Consumers of flowers and ornamental plants: an eploratory survey in the Italian «Mezzogiorno» regions

2010

This paper aims to provide further knowledge of purchase and consumption behaviours with regard to flowers and ornamental plants in the regions of Italian «Mezzogiorno», as an acknowledgement of the centrality of final demand in the chain process. The knowledge of consumption process is fundamental either to the firm – in order to improve commercial strategies – or to competition authorities – with the purpose of implementing more effective policies. From the analysis carried out it emerges that flowers and ornamental plants consumption in the «Mezzogiorno» regions is characterised by a high penetration index and – just with regard to some commodities – by a low purchase frequency. Purchase…

Enhancement of the Diversity of Pollinators and Beneficial Insects in Intensively Managed Vineyards

2021

Simple Summary The continuous intensification of agricultural production has resulted in higher yields and more yield security. However, these achievements went along with the substitution of heterogeneous agricultural landscapes by homogeneous ones with poor crop diversity, short crop rotations, and thanks to the high efficacy of modern herbicides and also to minimum in-crop diversity. A severe increase in plot size led to the elimination of ecologically valuable structural elements that had provided floral resources and nesting sites. Over the few last decades, several studies have been conducted to try to find solutions against insect decline and to preserve biodiversity. In the present …

Propagation of Calendula maritima Guss. (Asteraceae) through Biotechnological Techniques for Possible Usage in Phytotherapy

2022

The genus Calendula (Asteraceae) includes several species that are renowned for their therapeutic properties and/or use as ingredients in the preparation of cosmetics. The rare and critically endangered sea marigold, Calendula maritima Guss., an endemic species from Western Sicily, has also been recognized as a potential “farm plant species” for several important compounds used in cosmetics. However, the few remnant populations of this species are currently threatened with extinction because of several factors, such as hybridization with the congeneric species Calendula suffruticosa subsp. fulgida (Raf.) Guadagno and anthropogenic disturbance of its habitat. Therefore, in order to preserve …

Current air quality analytics and monitoring: a review.

2014

This review summarizes the different tools and concepts that are commonly applied in air quality monitoring. The monitoring of atmosphere is extremely important as the air quality is an important problem for large communities. Main requirements for analytical devices used for monitoring include a long period of autonomic operation and portability. These instruments, however, are often characterized by poor analytical performance. Monitoring networks are the most common tools used for monitoring, so large-scale monitoring programmes are summarized here. Biomonitoring, as a cheap and convenient alternative to traditional sample collection, is becoming more and more popular, although its main …

Classification of vegetable oils according to their botanical origin using amino acid profiles established by direct infusion mass spectrometry.

2007

Amino acid profiles, established by direct infusion mass spectrometry, have been used to classify vegetable oils according to their botanical origin. The proteins present in hazelnut, sunflower, corn, soybean, olive, avocado, peanut and grapeseed oils were precipitated with acetone, and the residue was hydrolyzed in acid medium, diluted in a hydrochloric acid/ethanol mixture, and infused into the mass spectrometer. The spectra of the hydrolyzed protein extracts showed [M+H]+ ions of the following amino acids: glycine, alanine, serine, proline, valine, threonine, cysteine, isoleucine + leucine, aspartic acid, lysine, glutamic acid, methionine, histidine, phenylalanine, arginine and tyrosine.…
