“…Hydroponicallygrown plant material is clean and easy to process due to minimal contamination from pollutants, pests and pathogens [10]. Floating systems is a hydroponic technique that is increasingly used for greenhouse production of fresh-cut leafy vegetables, including basil [11], and has also been utilized for the cultivation of medicinal plants [12,13].…”

Rosmarinic acid content in basil plants grown in vitro and in hydroponics

The accumulation of selected caffeic acid derivatives (CADs), in particular rosmarinic acid (RA), was investigated in different tissues (leaves, roots and plantlet shoots) of sweet basil (Ocimum basilicum L.) plants grown either in vitro or in hydroponic culture (floating system) under greenhouse conditions. Two cultivars with green leaves (Genovese and Superbo) and one with purple leaves (Dark Opal) were tested. The content of CADs in HCl-methanol extracts was determined by HPLC. LC-MS and LC-MS-MS were used to confirm the identification of the metabolites of interest. Apart from rosmarinic acid (RA) and a methylated form of this substance, no other CADs were detected at significant level in any of the analyzed samples. The content of RA ranged approximately from 4 to 63 mg/g DW, depending on the growing system. The highest RA content was found during the in vitro multiplication, in the acclimatized plants and in the roots of hydroponically-grown seedlings at full bloom. In vitro, 6-benzyladenine reduced the accumulation of RA in purple-leaf Dark Opal cultivar, but an opposite effect of this growth regulator was observed in the green-leaf genotypes. Our findings suggest the possibility to scale-up RA production by means of in vitro or hydroponic culture of sweet basil.

“…Conversely, limitation of P supply has been shown to decrease the production of floral structures (Arnon and Hoaglund 1943;Shamsi and Whitehead 1977;Ma et al 2001). Field studies on C. officinalis show low reproductive yield and greater production of leaf tissue compared to other deep culture, floating raft hydroponic systems (Dorais et al 2001).…”

“…We propose that the market demand for higher product output and higher product quality and safety can be met by using greenhouse cultivation methods for medicinal plants. Another advantage of adding medicinal plants to the array of greenhouse crops is that it allows greenhouse crop diversification (Agriculture and Agri-Food Canada 1998; Dorais et al 2001), and may bring high financial returns to growers (Sturdivant and Blakely 1999;Dorais et al 2001). At our latitude, in Canada (41°N), greenhouse cultivation allows crop production throughout the year (at least three full cycles would be feasible), and because of controlled nutrient and environmental conditions, and the opportunity for raising pesticide-free products by using biological methods for pest control, an increase in product quality and safety can be expected.…”

This has effectively created a strong public and regulatory demand for high quality, uniformity and safety of medicinal plant products. Greenhouse hydroponic cultivation under controlled environmental conditions allows the grower to provide pesticide-free conditions, lacking environmental contaminants, resulting in superior product quality and consistency.Calendula officinalis is evaluated here as an alternative greenhouse crop. Growing conditions (P concentrations) were manipulated in order to maximize flower-head (capitulum) yield, as these are the most valuable marketable structures. It was found that high P concentrations did not increase flower production, but instead produced significantly more leaf biomass. Plants receiving the lowest P concentration, with an intermittent watering regime, had the greatest absolute reproductive output, and greatest mass of all tissues assessed, except for leaf tissue. They also had the greatest proportion of biomass allocated to reproductive structures.Calendula officinalis shows promise as a medicinal greenhouse crop that requires low P levels for optimal capitulum (inflorescence) production (target tissue). Its xerophytic characteristics are best supported through modification of standard hydroponic systems; these modifications may be widely applicable to medicinal plants since many share Calendula's xerophytic characteristics. We conclude that discontinuous nutrient supply and relatively low ratios of P relative to N and K may enhance production of target medicinal tissues of Calendula officinalis. Les auteurs ont évalué l'utilité de Calendula officinalis en tant que culture de serre de rechange. Ils ont modifié les conditions de croissance (concentration de phosphore) afin de maximiser la production d'inflorescences (capitules), organe de la plante présentant la plus grande valeur marchande. Une concentration élevée de phosphore n'accroît pas la floraison, mais augmente sensiblement la biomasse des feuilles. Les plantes recevant la plus petite quantité de phosphore et arrosées de manière intermittente produisent le plus grand nombre absolu d'organes reproducteurs et la plus forte biomasse de tissus, à l'exclusion des feuilles. Les organes reproducteurs de ces plantes représentaient aussi la plus forte proportion de la biomasse. Calendula officinalis est une plante médicinale qui promet beaucoup pour la culture en serre, car il lui faut peu de phosphore pour donner un nombre maximum de capitules (le tissu visé). Ses propriétés xérophytes se prêtent particulièrement bien à la modification des systèmes hydroponiques habituels, qui pourraient alors convenir à la culture d'autres plantes médicinales, bon nombre d'entre elles partageant des propriétés analogues. On en conclut qu'un apport discontinu d'éléments nutritifs et une concentration relativement faible de phosphore, par rapport a celle d'azote et de potassium, pourraient accroître la production des tissus de Calendula officinalis aux vertus curatives.

“…Hydroponic production of medicinal and aromatic plants is a new trend in agricultural systems especially in organic agriculture 9,10 . Hydroponics provides many advantages, such as the standardization of the production process and the ease with which plants can be processed on an industrial scale 7 .…”

The research goal for the current study was to compare the essential oil composition obtained by hydro-distillation of aerial parts of Coriandrum sativum L. grown in three different cultivation systems (hydroponic, field and greenhouse). The Hoagland nutrient solution was used in hydroponic culture. The essential oil of aerial parts of C. sativum L. was obtained by hydro-distillation using a Clevenger apparatus. The analyses of the essential oils were carried out by using a GC-MS system. The major component of all oils was decanal; 25.8 %, 31.0 % and 34.77 %, respectively. Moreover, several mineral compositions (Na, K, Ca, Mg, Zn, Fe, Cu, Cr, Pb and Mn) in both field and hydroponic conditions were measured by flame atomic absorption spectrometry (flame AAS). The values of Pb and Cr percentage in two investigated samples of C. sativum were non-detectable.
