“…Cultivar-specific differences are likely one of the reasons for these different findings. This is supported by other studies in which postharvest storage at 6°C reduced total phenolics content compared with storage at 18°C in only one of four different basil cultivars tested (Kalisz et al, 2016). Contrary to the observations by Fratianni et al (2017), this cultivar (lettuce leaf basil) responded with increased phenolics production.…”

Fresh-cut sweet basil (Ocimum basilicum L.) is highly sensitive to low temperatures during postharvest storage. This study investigates whether preharvest foliar application of different concentrations of abscisic acid (ABA) can increase tolerance of the commercial basil varieties ‘Di Genova’ and ‘Nufar’ to chilling injury (CI) during postharvest storage at 3.5 °C and at 7 °C. Experiments were conducted under greenhouse and commercial open-field conditions in southwest Florida during the 2017/2018 growing season. Our results showed that greenhouse-grown plants were less affected by CI during 9 days of storage at 3.5 °C when treated with 1000 mg/L or 1500 mg/L ABA and at 7 °C storage compared with the water control, but effects varied by experiment. Preharvest applications of 1000 mg/L ABA were sufficient in reducing CI during cold storage at 3.5 °C in basil grown under open-field conditions; however, at 7 °C postharvest storage, chilling-induced damage did not differ between ABA and untreated plants. Electrolyte leakage analysis of leaves confirmed the beneficial effects of ABA on alleviating chilling-induced injury. Under greenhouse conditions, preharvest applications of 1000 mg/L ABA were more effective when plants were harvested at 1300 or 1530 hr than at 1100 hr. Our results suggest that 1000 mg/L foliar preharvest applications of ABA in combination with afternoon harvest are an effective strategy to alleviate CI damage during postharvest storage at temperatures less than 4 °C and to extend the shelf life of greenhouse or field-grown, fresh-cut basil.

“…The highest activity of SOD and GPX was achieved in T4-48, while this treatment caused the highest reduction in the activity of APX and CAT. Kalisz et al 10 reported a negligible alteration in CAT activity in all studied basil genotypes except Thai basil which showed a decline in CAT activity. They also stated the highest activity of peroxidases in Thai basil exposed to low temperature.…”

“…In our investigation, most of the cold treatments except T10-12 led to a DPPH expansion, which the highest level of that was obtained in T4-12. Kalisz et al 10 reported significant increases in DPPH in the red, lettuce leaf and cinnamon basil cultivars treated with 6 °C. They also reported that basil antioxidant properties (DPPH) are largely associated with TPC.…”

“…Antioxidant machinery includes antioxidant enzymes like superoxide dismutase (SOD) and peroxidases and several non-enzymatic antioxidants. Non-enzymatic antioxidants such as phenolic compounds (Phenolic acids and flavonoids) can trap and scavenge free radicals 9,10 . Also, environmental stresses and different ecological conditions substantially affect the EO content and constituents in medicinal plants.…”

environmental stresses might alter the activity of antioxidant defense system and both quantity and quality of the essential oil constituents in aromatic plants. in the current study, a greenhouse experiment was designed to assess the influence of cold stress on total phenolic (TPC) and flavonoid contents (TFC), DPPH radical scavenging, antioxidant and phenylalanine ammonia-lyase (PAL) enzymes activity and content of phenylpropanoid compounds in Ocimum basilicum L. the genes expression levels of chavicol O-methyl transferase (CVOMT), cinnamate 4-hydroxylase (C4H), eugenol synthase 1 (EGS1) and eugenol O-methyl transferase (EOMT) were also investigated. Results revealed the highest TPC, TFC and DPPH at 4 °C for 12 h. Positive significant correlation was observed between TFC and DPPH, as well as TPC and PAL enzyme activity. The highest activity of superoxide dismutase and guaiacol peroxidase was recorded in 4 °C for 48 h, while this treatment caused the highest reduction in the activities of ascorbate peroxidase and catalase. In plants exposed to 10 °C for 48 h, the contents of methyleugenol and methylchavicol was positively associated with the expression levels of EGS1 and EOMT. A positive correlation was also found between C4H expression and eugenol, methyleugenol and methylchavicol contents under 4 °C for 12 h.Ocimum genus, belonging to family Lamiaceae, is a source of economically valuable aromatic oils with medicinal properties. This genus possesses an extensive intra-and inter-specific genetic diversification including 65 to more than 150 species spread throughout the world 1 . Ocimum sanctum and O. basilicum (sweet basil), two high priority species in this genus, are extensively used for their pharmaceutical and industrial importance. O. basilicum L. (2n = 4x = 48), originally from India, Iran and Afghanistan contains multiple terpenoid and phenylpropanoid compounds which are used in medicinal and perfume industries 2 . This compounds mostly produces in glandular trichomes on the leaf surface 3 . The most important compounds related to fragrance property are linalool, 1,8 cineole, methylchavicol (estragole) and eugenol. Basil essential oil (EO) has anticancer and hypoglycemic tuberculosis properties 4,5 . Also cytotoxic property of ethanolic extract of basil containing eugenol has been reported on human laryngeal cancer cells 5 . Terpenoids and phenylpropanoids such as eugenol, methylchavicol, methyleugenol and cinnamate are the main constitutes of basil EO 4 . The major phenylpropanoid components of basil are methylchavicol and methyleugenol. These compounds are extensively used in perfumes, aroma therapy, food and medicinal industries. Methylchavicol stimulates liver regeneration, shows hypothermic and DNA binding and spasmolytic activities. Phenylpropanoid compounds is produced through shikimate pathway. Phenylalanine ammonia-lyase (PAL), involved in the initial step of phenylpropanoid metabolism, deaminates phenylalanine to generate trans-cinnamic acid and ammonia 3 . Cinnamate 4-hydroxylase (C4H), a cyt...

“…The most important nonenzymatic antioxidants include such compounds as: glutathione, ascorbic acid, flavonoids, tocopherols, or carotenoids [14]. Kalisz et al [15] observed that chilling increased l-ascorbic acid content in most tested basil cultivars. Low temperature may also affect the content of phenolics and anthocyanins in the plant [14,16].…”

Kale is a plant known and valued since antiquity as a healthy vegetable crop, used for culinary, decorative, but also healing purposes. The aim of the study was to examine the effect of harvest date on physiological status and nutritional composition of two kale cultivars: 'Winterbor' F 1 (blue-green leaves) and 'Redbor' F 1 (red-purple leaves). The leaves were harvested in three periods: before frost (>0°C), after medium (−5.0°C) and heavy frost (−15.0°C). Content of dry weight, soluble sugars, l-ascorbic acid, carotenoids, chlorophylls, polyphenols, anthocyanins, as well as antioxidant activity and peroxidase activity were determined. Cold temperature significantly affected bioactive compounds of kale. The content of dry weight, soluble sugars, l-ascorbic acid, phenolics, and antioxidant activity increased after medium frosts for both cultivars. The level of anthocyanins also increased significantly for the 'Redbor' F 1 cultivar. After strong frost, most of the tested parameters (content of dry weight, soluble sugars, phenolics, anthocyanins, and total antioxidant and peroxidase activity) significantly increased. The chlorophyll a content was reduced by heavy frost in both seasons. Harvesting kale before and after frost may allow the level of biologically active ingredients to be regulated as cold also significantly affects the physiological status of the plants.
