Physiological Parameters of Barley as Affected by Stripe Disease

Abstract

Stripe disease of barley caused by Drechslera graminea (Rabenh.) Shoemaker is a widely distributed disease in many barley grown parts of the world, but it has assumed more importance with the introduction of some new high yielding varieties. The present investigations were undertaken during 2007-08 and 2008-09 crop seasons with a view of elicit information on effect of disease on physiological parameters particularly chlorophyll content, leaf area, photosynthesis, stomatal conductance and transpiration. Stripe infection resulted in reduction of all the physiological parameters at both the stages i.e. 35 days and 50 days after disease appearance.
