Effect of Benzo (1,2,3) thiadiazole-7- carbothioic acid S- methyl ester (BTH) on biochemical responses of wheat seedlings infected by Fusarium culmorum
Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 12
Abstract
Fusarium culmorum is a ubiquitous soil-borne fungus able to cause foot and root rot on different small-grain cereals, in particular wheat and barley. Wheat (Triticum aestivum L.) is among the oldest and most extensively grown of all crops. Systemic acquired resistance (SAR) is a pathogeninduced disease resistance response in plants that is characterized by broad spectrum disease control. The effect of the resistance inducer, benzo (l,2,3) thiadiazole -7- carbothioic acid S-methyl ester (BTH) was tested by seed soaking to determine whether this resistance inducer controlled root rot of wheat caused by Fusarium culmorum. Systemic acquired resistance is an important component of the disease resistance repertoire of plants. (BTH) is a inducing disease resistance in a number of dicotyledonous and monocotyledonous plant species. In this study we have examined the factors chlorophyll a, chlorophyll b, total protein, Peroxidase enzyme, Total phenol and phenylalanine ammonia lyase (PAL). BTH, which is an important chemical inducer of systemic acquired resistance (SAR), can Activate resistance to pathogen infection in commercial crops. Seeds treatment with Benzothiadiazole showed an elevation in the activity of defense related enzyme, peroxidase.
