effect of safflower aqueous extracts foliar application on peroxidase enzyme activity and cell membrane leakage of hairy vetech

this experiment was carried out to evaluations the allopathic foliar application of safflower)carthamus tintorius) aqueous extracts on growth and leaf cell membrane leakage of hairy vetech (vicia villosa).  the experimental arrangement was crd in four replications. results showed that by increasing the concentration of safflower extracts, shoot dry weight and peroxidase enzyme activity decreased in hairy vetch. increasing the concentration of safflower extracts, increased malondialdehyde concentration and leaf electrical leakage in hairy vetech. the highest malondialdehyde concentration (0.202 nmol/fw) and the lowest shoot dry weight obtained from 15% safflower foliar extra application.
