“…Increasing the concentration above 80 mg L -1 resulted in a decrease in growth parameters. Chitosan oligomers have been reported to enhance the growth of fenugreek (Dar et al, 2015), eucalyptus (Ali, 2014), wheat and rice (Tham et al, 2001), orchid (Nge et al, 2006), and rape plants (Chmielewski et al, 2007). Darvill et al (1992) are of the view that plants recognize these oligosaccharides as elicitors, thereby regulating different aspects of growth and development and defense responses in plants.…”

“…Foliar applications of chitosan oligomers show biological activities (Chmielewski et al, 2007;Hossain et al, 2013;Ali, 2014) such as antifungal (Jeon et al, 2001), antitumor (Qin et al, 2002), and antibacterial (Zheng and Zhu, 2003) effects. These oligomers enhance growth in barley and soya bean (Luan et al, 2006), reduce the damage caused by vanadium in wheat and rice (Tham et al, 2001), enhance growth as well as essential oil (EO) content and yield in Eucalyptus citriodora Hook. (Ali et al, 2014), and enhance growth, biochemical, and yield parameters and alkaloid content in Trigonella foenum-graecum (Dar et al, 2015).…”

IntroductionDue to its considerable pharmaceutical importance, in addition to its use in food and cosmetics, Mentha piperita L. (peppermint) has always been a crop of interest. It has extensive uses in food, confectionaries, mouthwashes, chewing gums, toothpastes, herbal preparations, and various aromatherapy products (Lawrence, 2007). Its medicinal uses include antiinflammatory, carminative, analgesic, stimulant, emmenagogue, diaphoretic, antiemetic, antispasmodic, and anticatarrhal. It can also be used to treat anorexia, bronchitis, flatulence, ulcerative colitis, nausea, and liver complaints. Peppermint oil can also be externally applied for antiseptic, antipruritic, rubefacient, antimicrobial, and astringent purposes, in addition to its use for the treatment of migraines, headaches

“…Further, COS may perform phytohormone-like activity altering genetic expression and manipulating cellular signalling 76 . Earlier reports have also established the eliciting activities of irradiated chitosan on the growth and development of several plants such as Malabar spinach 77 , Brassica rapa 78 , Triticum aestivum 79 , Oryza sativa 79 , Cymbopogon flexuosus 44 , Glycine max 79 , Trigonella foenum-graecum 80 , Hordeum vulgare 79 , and Solanum tuberosum 81 under normal and stress environments.…”

Plant susceptibility to salt depends on several factors from its genetic makeup to modifiable physiological and biochemical status. We used lemongrass (Cymbopogon flexuosus) plants as a relevant medicinal and aromatic cash crop to assess the potential benefits of chitosan oligomers (COS) on plant growth and essential oil productivity during salinity stress (160 and 240 mM NaCl). Five foliar sprays of 120 mg L−1 of COS were applied weekly. Several aspects of photosynthesis, gas exchange, cellular defence, and essential oil productivity of lemongrass were traced. The obtained data indicated that 120 mg L−1 COS alleviated photosynthetic constraints and raised the enzymatic antioxidant defence including superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD) activities that minimised salt-induced oxidative damage. Further, stomatal conductance (gs) and photosynthetic CO2 assimilation (A) were improved to support overall plant development. The same treatment increased geraniol dehydrogenase (GeDH) activity and lemongrass essential oil production. COS-induced salt resilience suggests that COS could become a useful biotechnological tool in reclaiming saline soil for improved crop productivity, especially when such soil is unfit for leading food crops. Considering its additional economic value in the essential oil industry, we propose COS-treated lemongrass as an excellent alternative crop for saline lands.

“…Los estudios del efecto del V en la germinación son escasos, si bien se ha reportado que el tratamiento con 50 mg V/mL reduce el porcentaje de germinación de semillas de trigo, cebada, arroz y soya en 52, 65, 4 y 6 %, respectivamente. Además, el tratamiento con 100 mg V/mL redujo el porcentaje de germinación relativa en 90, 85, 5, y 6 %, respectivamente (Tham et al 2001).…”

“…La aplicación de vanadio (V) en el rango de 50 a 100 µg/mL disminuyó el porcentaje de germinación en soya (Glycine max), trigo (Triticum aestivum), cebada (Hordeum vulgare) y arroz, y redujo significativamente la biomasa total de las plántulas (Tham et al 2001). Así también, concentraciones de V de 2.5 mg/L disminuyeron la longitud de radícula en nabo en 49 %, en col (Brassica oleracea var.…”

Se evaluaron de forma independiente los efectos de los metales cadmio (Cd), talio (Tl) y vanadio (V) a concentraciones de 0, 25 y 50 µM cada uno, en indicadores de germinación y crecimiento inicial en tres variedades de chile: jalapeño, poblano y serrano. Las semillas fueron tratadas durante 15 días y se cuantificó el número de semillas germinadas en intervalos de 24 h para la obtención del porcentaje de germinación (PG). Al final de este periodo se determinaron el porcentaje relativo de germinación (PRG), las longitudes de vástagos (LV) y raíces (LR), el crecimiento relativo de radícula (CRR), el índice de germinación (IG) y el coeficiente de velocidad de germinación (CVG). Los tratamientos no afectaron al PG ni al PRG. Los principales efectos de los factores de estudio se observaron en indicadores relacionados con el crecimiento inicial. La tolerancia de las variedades de chile evaluadas a los metales en estudio fue, en orden decreciente, jalapeño > poblano > serrano. El Tl en particular fue altamente fitotóxico en la variedad serrano; por el contrario, el Tl incrementó la LV en las variedades jalapeño y poblano. El Cd estimuló la LV del chile poblano, en tanto que el V estimuló el CVG en el chile jalapeño y la LV del chile poblano. Se concluye que el Cd, Tl y V producen efectos diferenciales entre genotipos, mismos que son dependientes de la variedad de chile probada, la concentración del metal evaluado y la fase de desarrollo (germinación o crecimiento inicial).
