Studies on the impact of fluoride toxicity on germination and seedling growth of gram seed (Cicer arietinum L. cv. Anuradha)
Journal Title: Журнал ÑтреÑÑ-физиологии и биохимии - Year 2012, Vol 8, Issue 1
Abstract
The influence of 0, 0.1 mM, 0.5 mM, 1.0 mM, 4.0 mM, 8.0 mM fluoride (F) concentration on seed germination, seedling growth of gram seeds (cv. Anuradha) was studied under laboratory condition. At the end of 15 days of treatment, significant reduction in root length, shoot length, dry weight, fresh weight, % of germination, protein content, catalase activity, tolerance index, vigour index, germination rate, germination relative index, mean daily germination were observed at increasing fluoride concentration. Total soluble sugar content, proline content, peroxidase activity, ascorbic acid oxidase activity, % DFC, % phytotoxicity of root and shoot increased along with gradual increment of F concentration. 4.0 mM F concentration was found to be most sensitive for gram seeds. At 8.0 mM F concentration germination occurred but plants were totally dried after completion of treatment period.
