“…Such metabolites are contained in secretory cells, epidermal cells, cavities, channels, or glandular trichomes (Yang et al, 2014). Liu et al (2011) clarified that the greatest accumulation of metabolites is attributed to the closure of plant stomata in the prolonged drought period. The effect of water stress can be observed in other studies, such as that of Jaleel (2008), where Catharanthus roseus L. produced more ajmalicine under stress conditions.…”

“…The availability of water changes the production of metabolites, and stress positively stimulates the production of some metabolites such as cyanogenic glycosides, glucosinolates, anthocyanins, alkaloids, and some terpenoids (Liu et al, 2011). Samples collected during winter showed the following chemical composition: β-myrcene (40.20%), germacrene D (14.09%), epicurzerenone (13.70%), 2-undecanone (6.05%), curzerene (5.47%), and ɣ-elemene (5.01%), as described in Table 1.…”

“…The fact that these plants are shrubs and groves that develop in the interior of the forest in an environment with low radiation is less relevant, differing from other medicinal plants that present higher production of essential oils in periods with higher radiation (Liu et al, 2011). The production of essential oils in the spring season did not show significant changes compared to the production in the summer season; however, it was observed that the content of β-myrcene in the summer (24.20%) was inferior when compared to that in the spring (34.67%), as shown in Table 1.…”

“…Therefore, a higher composition was found in the summer, even after taking into account the different quantities extracted throughout the year. Liu et al (2011) concluded that the amount of available radiation and the wavelength type are the factors that alter the composition of the essential oil; the incidence of UV radiation is a factor that contributes to the increased production of certain secondary metabolites.…”

The plant Siparuna guianensis is used in traditional medicine and has been the target of studies on the development of new drugs for the control of pests and vector insects. The present study was aimed to evaluate the seasonal influence on the content and composition of the essential oil of S. guianensis. The experiment was conducted for 12 months evaluating the yield of the essential oil of leaves throughout the seasons (autumn, winter, spring and summer). The chemical composition of the essential oil was obtained by gas chromatography-mass spectrometry (GC-MS). The highest oil yield was in autumn and winter, comprising 0.33 and 0.29% (w/w), respectively. The major compound identified was β-myrcene (48.59-24.2%), followed by epicurzerenone (27.24-13.7%) being the most abundant; germacrene D showed lower values of 9.93% in autumn and 13.5-14.34% in the other seasons, besides curzerene that had no production in autumn. The ɣ-elemene component had a higher production of 7.29% in autumn. Compound 2-undecanone did not show significant seasonal changes, with percentages being between 7.26 and 5.43%. The monoterpenes and sesquiterpenes showed similar levels in autumn; however, in the other seasons (winter, spring, and summer), the sesquiterpenes presented higher concentration, reaching 68.54% in summer. The components identified in the essential oil of S. guianensis exhibit interesting biological activities, making this essential oil a promising compound for the development of new biodegradable drugs, repellents, and insecticides. The knowledge about the yield and seasonal composition is fundamental to optimize and maximize the obtainment of compounds of interest for the production of new drugs.

“…In general, drought stress has profound effects on plant physiology, productivity and growth. Water stress can affect the growth of plant organs differently, thereby resulting in the alteration of the morphological traits of the plants, such as plant height, leaf area and dry weight (Liu et al, 2013;Sapeta et al, 2013). Plants have developed a wide diversity of morphophysiological drought tolerance mechanisms (Blum, 1996).…”

Water deficit is the largest limiting abiotic factor in agriculture and will increase in future. Evaluating the drought stress-induced changes in growth parameters as well as the leaves ethylene accumulation of medicinal plants to grow these in arid and semi-arid areas has particular importance. Chicory (Cichorium intybus L.) is a famous medicinal herbal plant which grows in most parts of Iran. A factorial greenhouse experiment was conducted to evaluate the effect of drought stress [100 (as a control), 80, 60 and 40% of field capacity (FC)] on morphophysiological parameters as well as the leaves ethylene accumulation of four chicory ecotypes. The results showed a significant effect of drought on plant height, leaf area, shoot moisture content and total dry matter production of chicory ecotypes which were reduced under drought stress. Under increasing drought level the Siyah Shiraz (Kh) ecotype performed better by maintaining more growth characters, thereby leading to more production of dry matter than the other ecotypes. Isfahan ecotype was the most affected by rising tensions and showed more reduction in growth traits. Drought stress also considerably changed leaf ethylene content, that made the leaf ethylene biosynthesis to be significantly higher under severe (60 and 40% FC) stress when compared to control (100% FC) and was significantly higher in drought-tolerant chicory ecotype (Kh). In general, it can be concluded that Kh was superior to other ecotypes in terms of growth and leaves ethylene accumulation, and can be suitable for cultivation in arid regions.
