Estimation of Primary Metabolites and Phenols in the Seeds of Five Species of Calamus and their Role on Germination

Effects of Seed Invigoration Treatments on Seed Germination, Seedling Vigour and Physio-biochemical Characteristics of Angelica glauca EDGEW –An Endangered Medicinal Herb

“…The beneficial effects of growth substances have been attributed in overcoming dormancy by causing changes in seed coat ultra structure (Solichatun et al, 2016), membrane repair, increased protein synthesis and more efficient mobilization of sugars and proteins (Srinivasan et al 1999). In addition underlying key Physiological processes like mobilization of (Yang et al, 2016;Tejavathi et al, 2017;Zhao et al, 2018). Improved germinability of seeds by invigoration is associated with a lower rate of lipid peroxidation and higher antioxidant enzyme activities (Bailly et al, 2000).…”

“…Significance of presowing seed treatments to break dormancy and improve the germination ability of seeds is well established (Thakur, 2008;Bhardwaj et al, 2016;Thakur and Himangini 2015;Negi et al, 2017). Key Physiological phenomena like mobilization of stored reserves, imbibitions phenol content and other biochemical changes play a crucial role during seed germination (Yang et.al, 2016;Tejavathi et al, 2017;Zhao et al, 2018). Therefore, efforts were made in the present study to test the efficacy of different presowing treatments to remove dormancy, improve overall germination percentage and vigour and also to understand the underlying physiobiochemical changes for boosting conservation.…”
