بررسي تغييرات مقدار فنل كل در واكنش دو رقم گندم مقاوم و حساس در برار آلودگي به PUCCINIA STRIIFORMIS

Study on the changes in total phenol content in two resistant and susceptible wheat cultivars in response to Puccinia striiformis infection

The total phenol content of two wheat cultivars Mv17 (as resistant) and Bolani (as susceptible) were determined at different times after inoculation with race 134E150 of Puccinia striiformis. Samples were taken at 24,48,72,100,144,and 216 hours after inoculation.The result showed a rapid increase in total phenol content of inoculated leaves of resistant cultivar. It was 3 times higher than that in susceptible cultivar at 100 hour after inoculation. There was no significant difference in total phenol content between inoculated susceptible cultivar and control. In general it was concluded that there was a relationship between resistance in Mv17 and accumulation of phenolic compounds.
