@article{Ramalingam Sridharan_2015, title={Infl uence of indole-3-butyric acid and triazole compounds on the growth and antioxidant constituents in Ashwagandha (Withania somnifera L.) Dunal}, volume={1}, url={https://www.updatepublishing.com/journal/index.php/jmhe/article/view/2867}, abstractNote={<p>Withania somnifera (L.) Dunal belongs to the family Solanaceae and commonly known as Ashwagandha, Indian<br />ginseng and winter cherry is major ayurvedic medicinal plant cultivated specifically for its root portion, which<br />has medicinal and nutritional values due the presence of clinically important active compounds such as steroidal<br />lactones, alkaloids, flavonoids, and tannins etc. Ashwagandha root is the medicinal part of the plant and is used<br />in the ayurvedic formulations and pharmaceutical industries. The present study was undertaken to investigate the<br />influence of indole-3-butyric acid (IBA) and triazole compounds viz., triadimefon (TDM) and propiconazole (PCZ)<br />on the growth and non-enzymatic antioxidant content of Ashwagandha. Plants were treated with IBA 2.5 mg/L,<br />TDM 20 mg/L and PCZ 20 mg/L separately by soil drenching on 50, 90, 130 days after sowing (DAS). Plants<br />were analyzed on 60, 100 and 140 DAS and it’s parameters such as shoot length, internodal length, number of<br />leaves, total leaf area, fresh and dry weight of shoot, root length, root diameter, number of roots, fresh and dry<br />weight of root, ascorbic acid (AA), α-tocopherol (α-toc) and total phenol (TP) contents were determined. It was<br />observed that shoot length, internodal length, the number of leaves, total leaf area, fresh and dry weight of shoot<br />decreased, but the root length, root diameter, number of roots fresh and dry weight of roots were increased<br />higher level. Likewise, the non-enzymatic antioxidants constituents such as AA, α-toc and TP contents were<br />also increased by TDM and PCZ treatments. But IBA treatment increased all the parameters studied. Among the<br />treatments, triazole showed beneficial growth by increasing the biomass of root system antioxidant constituents<br />when compared to IBA treatment. This finding suggested that the triazole compounds showed a great significant<br />for the cultivation of medicinally important root crops, which is helpful to meet the needs of root production by<br />enhancing antioxidant constituents in Ashwagandha.</p>}, journal={Journal of Medicinal Herbs and Ethnomedicine}, author={Ramalingam Sridharan, Panneerselvam Sakthivel}, year={2015}, month={Nov.}, pages={13–23} }
