Abstract

Petri-dishes grown seedlings of wheat cvs. Margalla 99 and Chakwall 97 were treated with distilled water and with different extracts of sunflower roots. Data on physiology of wheat seedlings including germination rate, protein, proline, sugars, DNA, peroxidase, superoxide dismutase and chlorophyll contents were recorded; all increased with allelochemicals treatments when compared with the controls.

 

Key words: Allelopathy, chlorophyll contents, DNA, peroxidase, protein, proline, sunflower, sugar, superoxide dismutase, wheat.
