摘要：An experiment was conducted to investigate the growth regulatory activities of different extracts of Tinospora cordifolia on radish ( Raphanus sativus ), swamp cabbage ( Impoea aquatica ) and lady’s finger ( Hibiscus esculentus ) with the attempt for chemical investigation of effective plant extract. The chloroform extract of Tinospora cordifolia significantly increased and enhanced germination, growth of shoot length and root length of radish and lady’s finger whereas and delayed germination, growth of shoot length and root length of swamp cabbage seeds compared with control. In the same way, ethanol extract of Tinospora cordifolia significantly increased germination, growth of shoot length and root length of swamp cabbage followed by control and chloroform extract. Our study reveals that different extracts of Tinospora cordifolia contain growth regulatory active principle. Among the extracts, chloroform extract was shown better performance in terms of percent germination, growth of shoot and root length of radish and lady’s finger. To find out effective compound from chloroform extract, thin layer chromatography was done and showed five distinct compounds. Further study is needed to determine structure for finding growth regulatory compound for agricultural usage. DOI: http://dx.doi.org/10.3329/jesnr.v5i1.11568 J. Environ.
