“…Indeed, genetic diversity stimulated by geographical distances within Ocimum sp. (1,2), as well as environmental conditions, plays a major role in the chemical composition of the essential oil (27). In this study, we found a variation from the chemical composition documented in the literature on Egyptian local basils and this variation mainly contains methyl cinnamate (43.8%) as a major compound in the essential oil.…”

Ocimum sp. taxonomy and nomenclature are in a state of confusion; thus species and cultivar identification are hampered by the large number of species belonging to this genus. In this study, we examined DNA barcoding and leaf essential oil (EO) composition methods for cultivar identification of local and recently introduced Ocimum sp. Both barcodes of rbcLa and matK were sequenced for each species in parallel with leaf EO composition analyses using gas chromatography and GC-mass spectrometry (GC-MS) of five Ocimum basilicum cultivars. Antioxidant activities for the EO were determined using 2,2′-diphenypicrylhydrazyl (DPPH) and β-carotene-linoleic acid assays. The main EO constituents were methyl cinnamate (43.8%) in O. basilicum L., chavicol methyl ether (39.1% and 32.3%) in O. basilicum purple ruffle and anise; respectively, and linalool (30.9% and 30.6%) in O. basilicum Genovese and bush green, respectively. All cultivars were classified into chemotypes easily using their EOs when compared with barcoding using core barcodes, which exhibited no variation among all species in both markers except for Ocimum americanum, varying in a single base pair in matK. We concluded that chemotyping performed better than barcoding in species and cultivar identification, and the search for a better barcodes should continue.

“…In some aromatic herb crops UV has been used for modulation of aroma. Examples of induction of flavor-related compounds by UV have been reported in basil and peppermint (Johnson et al, 1999; Chang et al, 2009a; Behn et al, 2010; Dolzhenko et al, 2010; Hikosaka et al, 2010; Bertoli et al, 2013). These wavebands have even been suggested to be required for normal development of oil glands in basil (Ioannidis et al, 2002).…”

Light Quality Dependent Changes in Morphology, Antioxidant Capacity, and Volatile Production in Sweet Basil (Ocimum basilicum)

Narrow-bandwidth light treatments may be used to manipulate plant growth, development and metabolism. In this report LED-based light treatments were used to affect yield and metabolic content of sweet basil (Ocimum basilicum L. cv “Ceasar”) grown in controlled environments. This culinary herb produces an aroma highly appreciated by consumers, primarily composed of terpenes/terpenoids, phenylpropanoids, and fatty-acid- derived volatile molecules. Basil plants were grown under narrow-bandwidth light conditions, and leaf area, height, mass, antioxidant capacity and volatile emissions were measured at various time points. The results indicate reproducible significant differences in specific volatiles, and in biochemical classes of volatiles, compared to greenhouse grown plants. For example, basil plants grown under blue/red/yellow or blue/red/green wavelengths emit higher levels of a subset of monoterpenoid volatiles, while a blue/red/far-red treatment leads to higher levels of most sesquiterpenoid volatile molecules. Specific light treatments increase volatile content, mass, and antioxidant capacity. The results show that narrow-bandwidth illumination can induce discrete suites of volatile classes that affect sensory quality in commercial herbs, and may be a useful tool in improving commercial production.

The introduction of high power LED lighting systems for horticulture has stimulated substantial interest from both the research community and the protected horticulture industry. LED lighting systems have the potential to reduce electrical energy consumption compared to conventional high pressure sodium lights and their energy efficiency continues to improve. In addition to the potential of LEDs to reduce carbon footprints and reduce running costs, LED lighting also provides considerable opportunities to exploit the wealth of photobiological knowledge to produce horticultural benefits. The narrow emission spectra of LEDs allows lighting systems to be tightly designed to stimulate specific plant photoreceptors, allowing plants to be manipulated to produce desirable characteristics. Lighting systems can be designed to maximize growth, control morphology, and optimize flavor and pigmentation. This review outlines how the light spectrum influences photosynthesis and how plant photoreceptors sense light and control growth. The review then discusses the ways in which this knowledge is being implemented in commercial horticulture to improve factors such as yield, flavor, color, plant growth, and flowering as well as pest and pathogen management and control. Research in this area is moving rapidly as the LED systems improve and increase in efficiency and as the range of novel horticultural applications expands.
