Effect of Heterodera avenae on the growth, photosynthesis and chlorophyll content in triticale

The studies on the growth of triticale as affected by Heterodera avenae revealed that the characters like shoot and root fresh and dry weights, leaf area, number of leaves and tillers and grain weight were adversely affected than shoot and root length with the increase in the level of inoculum. At 4 J2/g soil, there was significant decrease in these growth parameters but at 1 J2/g soil level there was stimulatoy effect. Photosynthesis, photosynthetic efficiency as also the chlorophyll content of leaves was found to be lower at higher levels of nematode density.
