Pot-grown seedlings of wheat cvs. Margalla
99 and Chakwall 97 were treated with water mixed with
extracts of sunflower leaves, stems and roots at 20 days
after the seedlings emerged. Data on physiology of wheat
seedlings including protein, proline, sugars, DNA,
peroxidase, superoxide dismutase and chlorophyll contents
were recorded; all increased with allelochemicals treatments
when compared with controls.
Key words:
Allelopathy, chlorophyll contents, deoxiribonucleic acid,
peroxidase, protein, proline, sunflower, sugar, superoxide
dismutase, wheat. |
