Germination and seedling growth of two summer vegetables influenced by aqueous extract of few ornamental plants

摘要

An experiment was conducted separately in pot and petridish to study the effects of aqueous extracts of few ornamental plants viz. Parrot tree ( Butea monosperma ), Indian Medlar ( Mimusops elengi ), Bougainvillea ( Bougainvellia glabra ), Powder puff ( Calliandra surinamensis ), Garland flower ( Hedychium coronarium ), Chinese honey - suckle ( Quisqualis densiflora ) on the germination and growth of two summer vegetables namely Cucumber ( Cucumis sativus ) and Yard long bean ( Vigna unguiculata ). In creased germination as well as root length and shoot length of both vegetables were found with the aqueous extract of Powder puff ( Calliandra surinamensis ) in compared with the control treatment. Aqueous extract of Indian Medlar found to decrease the germi nation and growth of two vegetables. The thin layer chromatography (TLC) test revealed the presence of five distinct compounds in the aqueous extract of powder puff at Hexane : Ethyl acetate (2:1 v/ v ).
