dc.description.abstractThe present research entitled “Studies on the effect of elicitors in Chamomile (Matricaria chamomilla L.) grown under abiotic stress conditions” was carried out in the polyhouse as well as in the laboratory of Department of Forest Products, Dr. Y S Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2022-2023. The seeds were sown in the nursery on 18th October, 2022. The seedlings were transplanted in earthen pots on 7th December 2022. The plants were subjected to water and salt stress conditions after 1 month of transplanting. The foliar application of elicitors was initiated at the vegetative stage and 2nd spray was given after 10 days of first spray. In water stress conditions, the plants without stress conditions show the highest growth performance and herbage yield- plant height (85.19 cm), no. of leaves per plant (476.67), no. of flowers per plant (316.45), fresh herbage yield per plant (303.47 g), dry herbage per plant (35.57g), fresh flower weight per plant (42.07 g), dry flower weight per plant (10.09 g), total chlorophyll content (3.00 mg/g) and total carotenoid content (0.94 mg/g). However, the maximum essential oil content (0.48%) was recorded at 50% FC with 0.5 mM acetyl salicylic acid and maximum essential oil yield (0.16 g/plant) was observed at 75% FC with 1.0 mM acetyl salicylic acid. In biochemical content, plants at 50% FC with 0.5 mM salicylic acid gave the maximum phenolic content (145.18±2.91 GAE/g), total flavonoid content (104.2±1.93 RE/g), maximum percentage of DPPH radical scavenging activity (64.11±1.95). Maximum percentage of hydroxyl radical scavenging activity (62.14±2.13) and maximum absorbance of reducing power activity was recorded at 50% FC with 1.0 mM salicylic acid. The nitric oxide scavenging activity (52.77±2.89) was recorded at 50% FC with 0.5 mM acetyl salicylic acid. In salt stress treatment, maximum growth and yield was observed in plants at 25 mM NaCl with 1.0 mM salicylic acid- plant height (99.84 cm), no. of leaves per plant (544.33), no. of flowers per plant (357.67), fresh herbage yield per plant (398.67 g), dry herbage yield per plant (40.87 g), fresh flower weight per plant (54.40 g) and dry flower weight per plant (14.08 g). However maximum essential oil content (0.55%) and essential oil yield (0.34 g/plant) were recorded in 50 mM NaCl with 1.0 mM acetyl salicylic acid. The maximum carotenoid content (1.13 mg/g) was found in 25 mM NaCl with 1.0 mM salicylic acid. Chlorophyll a and total chlorophyll content was recorded highest in control conditions. In biochemical content treatment, 50 mM NaCl with 0.5 mM Salicylic acid gave the maximum phenolic content (128.61±1.84 GAE/g). Maximum flavonoid content (106.13±1.95 RE/g), maximum percentage of DPPH radical scavenging activity (66.55±0.74) and, maximum absorbance of reducing power activity (0.844±0.012) was recorded at treatment 50 mM NaCl with 1.0 mM Salicylic acid. The maximum percentage of hydroxyl radical scavenging activity (77.19±2.99) and nitric oxide scavenging activity (67.12±2.01) was observed as the treatment of 50 mM NaCl with 0.5 mM acetyl salicylic acid. Saponin and alkaloids were detected in all the treatments under water and salt stress.
